Holley: "Carburetors are dead" Edelbrock: " Hold my beer" - The New VRS 4150 Is The Ultimate Carb

[@benjaminpendley6116]

Our shop and all around us have had none, I repeat, NONE of the new tbi fuel injection systems last or work at all. Not from any manufacturer at any price point. Our first recommendation to shit running cars is “take that damn efi off”

Ben, I'm going to pin this comment, because I think what you're saying holds true for many people, and I think this would be a good point of discussion.

[@rustybritches6747]

I'm not a fan of the Holly EFI stuff but I can tell you when it first started getting big my buddy bought a holly sniper system hooked it all up and two of the injectors were dead right out of the box! they did send him a complete new setup with the handheld touch screen and everything they didn't just replace the injectors they sent him a whole new kit and he has had it on at least two different engines but I'm still not a fan even though driveability is great cold starts are great but it's just not for me! so carburetor all the way!

[@sixtyfourchebby4507]

It's amazing how many people's projects sit after an efi failure. It was a lure to alot of people nearby because of the drastic elevation and temperature changes we experience. It was 54°C (129°) for over a week in my community in Canada and I drove carbureted vehicles everyday. No undrivability problems. And then 3 months later.... foots of snow and again no carburetor issues... maintenance is key. Take care from Quasi Mofo The Hunchback of Canaderp

[@Freedom_is_better_than_safety]

I have to be honest here, making a blanket statement that there isn’t a good TBI aftermarket fuel injection system available now sounds like you’ve written them off without ever installing, tuning and maintaining them. Their early systems had a high failure rate, and the use of overseas sourced parts hasn’t made them flawless, but I’ve had a FITech and a Holley Sniper both perform very well over the last few years without issue. Are they the solution for everyone? No, there isn’t one way to do things. But to condemn the idea of adding EFI to an originally carbureted car as unreliable or too problematic simply isn’t true. Keeping an open mind and accepting that innovation happens doesn’t mean there’s no place for a mechanical carburetor any more than saying there’s no use for an older car now that we have airbags, ABS, and other important safety features. If you learn the systems and work on them they have their merits, as well as some drawbacks. But I will say they’ve kept more than a couple of my friends driving their classic cars because they don’t seem to need quite the same level of constant tuning as many old carburetors do. But maybe I’m just seeing it from one angle as well.

[@74stang2togo]

The 650cfm Edelbrock on my Mustang sat in my parents' garage, getting crapped and pissed in by rats, and clogged with rat nest material for seven years. When I finally gave up on the MSD Atomic EFI that I'd been running, I picked the Edelbrock up, dumped the rat debris out, sprayed it out with carb cleaner, bolted it onto the engine, primed it, and started it... and haven't touched an adjustment screw or anything else. It's the AK47 of carburetors, it doesn't care how it's been treated, it just works.

[@Thumper68]

What? So many people struggle with them I see it’s ridiculous. In my opinion the Holley is kinda the ak47 of carbs. Really a new Quadrajet is the true ak47 of carbs becuase you can easily start vehicle with one of them on extreme sidehill or angle and others won’t.

[@WilleJamesHuff]

Love edelbrocks. Got in a pinch for a big truck show I was going to and my carb got some trash in it. Bought a 600 edel off the shelf at parts store, out of the box bolted on and drove it 3 hours to that show with no issue. I like Holley but I really doubt you’ll do that with one

[@DieHolden]

I've bought both Holley and Edelbrock and installed them out of the box and they ran fine. What we like about the old holley's and well autolites for me was how easy they were to tune. The AFBs used to be what they called cat's pajamas. But recently I was looking at one of the newer Edelbrock carbs that have improved on their old designs. I have thought about going to an aftermarket fuel injection. I cut my teeth so to speak on mechanical fuel injection and Bosch fuel injection and then afterwards learned carburetion. So I have the skills to do the aftermarket injection if I decide they have the longevity that a simple carburetor would give me. I'm only considering it because I don't like Ford's ridiculous batch fire injection on an old truck I have. I might never be happy with it and just sell it and get something that might make me happy later.

Such a good, simple reliable carb. They just work.

A holley carb is known as a plain tube carb eldebrock is a air valve carburetor. Holleys have a more dense charge below the throttle plate then edelbrock or carter's because there not pushing on a spring loaded door.

[@chrisleggett685]

About 15 years ago I was putting my #1850 on my rebuilt engine and I broke an ear off the baseplate. Went and bought a 600 Edelbrock and used that. It had lean stumbles and just plain ran poorly. Took the truck to the local hot rod shop. Put it on the Dyno and spent a day trying to tune that carb. Never did get it perfect. We were down to hand sanding the metering rods to try to get it to work. Did the best we could. I drove it a few weeks untill I found a used baseplate for my Holley so I put that carb back on. Went back to the chassis Dyno and the unmodified Holley with a used baseplate put out 60 more HP and 90 ft lbs more than the Edelbrock. That sold me on Holley's.

[@ColdSmokes]

I recently purchased two different Holley's. The first was a Slayer 600 and the second was a 4150 Demon which used to be the Barry Grant deal. Engine runs @180°F with 1/2" heat insulator under carb. Both would boil the fuel out of the accelerator pump circuit leaving it dry when you needed it. Both would pour fuel from the secondary throttle shafts and leave puddles of fuel on the intake manifold. Both required heavy throttle for hot starting due to fuel percolating into the engine. Both went back to Summit and I put on an AVS2. Tony is right, the thing just works. I purchased an 800 AVS2 to see if it would run any better than the 650 and it really didn't. The 800 fooled you because it felt quicker because the primary barrels are a lot bigger but overall, 800 was not worth keeping so I sold it. I recently installed a basic but Blueprinted 600 cfm AFB Performer and it works even better than the 650 AVS2. Go figure! I am quite convinced the silly red annular boosters on the AVS2 are marketing hype.

The first Holley trick I learned from a couple of mechanics who had a shop I worked detailing next to all through high school and showed me how to make the secondaries work circa fall 1970. I had built my first hot engine a 273 and it had a 290 degree crower cam cam, TRW 10.5to 1's ,cyclone fenderwell headers a mallory dual point dist.and a D4RB edelbrock manifold with a holley 600. I had broken it in carefully and now wanted it to run now . Echevaria and Rodrigues ,the two mechanics smiled at each other and said "The sheet metal screw trick" One of them disappeared into the shop and came out and inserted a sheet metal screw in the secondary pull off slot that closes the secondaries .They were about ten years older than me,had set up my mallory dual point and told me they wanted to hear me get on my 63Valiant v100 coupe in all four gears on the expressway next to the shop or they would severely punish me (They were Chevy guys). I did and could not stop grinning for about a hour after. It ran bitchin compared to the 170 and 225 slants I had the previous year after getting my license. The sheet metal screw gets rid of the vacuum secondaries control and makes Them open NOW.

This is awesome! I’ve owned both Holley and Edelbrock. Both are iconic brands, but most of my old trucks are/were daily driven or weekend cruisers and I agree, Edelbrock is just the best for that kind of operation. I’m a former diesel technician but have minimal experience with carbs but I can setup and rebuild an Edelbrock with ease. My last carburetor I had on my Chevy K10 was an Edelbrock 1408 and according to Edelbrock it was from 1992 and it just went bad! 30 years! I replaced it with the 1406 for a mild 350. I’ve daily driven Edelbrocks for years and through winters and never had to touch them, so easy to setup once you take the time to learn. Very disappointing to hear about Holley going away from carburetors, I’ve owned around 20 vehicles and I’ve had more issues with throttle bodies and EFI than any carburetor I’ve owned. Again, former diesel technician, big killer for those engines are injectors and injection pumps. I’ll gladly stick with the old school and reliable carburetors!

Check out 2020 screen, or "pet resistant" screens. Very hard to tear. Also, they are fiberglass, not nylon. Some screens even keep out no-see-ums.

Nylon/fiberglass took over for a few reasons.

@@Face2theScr33n I meant to say fiberglass instead of nylon. Will have to check out the pet resistant. I have an old house and wish to continue with wooden screen frames. I don't need any rollers or splines, just some tacks. I remember people thinning some black oil paint and recoating the screens after the galvanizing wore off. Also they could be patched with a scrap of screen if something did make a small hole.

[@wynniepopspeedshop3193]

Carburetors aren't dead. I couldn't agree more because I do the same thing. For quick and easy street use I use edelbrocks. For maximum tuning I go for holleys. I used to be a hard-core holley guy but like you said you can't beat the ease of a Carter style edelbrock. I say screw holley for giving up on carbs. Carburetors forever!

[@Zerinsakech]

I had an edelbrock on a chevy 350 pickup truck, so reliable. It amazed how boring and simple it was. My daily driver slant 6 had a Holley 390. So much tinkering. I liked both but for different reasons. Mechanical carbs are just cheaper and simpler in the end. EFI everything doesn't always make sense, but when it comes to today's fuels it can really gum them up when you don't drive them daily. I've had to fix so many scooter and motorcycle carbs just because the fuel in the carbs messed them up. When it comes to Fuel injection it's great but it has it's place. doesn't mean it should go everywhere.

[@finscreenname]

There is a reason I use Edelbrock on all my boats. Not sure how any Holley carb was ever marine certified. Bowl gaskets, metering block gaskets, etc, etc all are leaking points and most boats sit for the winter or a number of months, gaskets dry up and leak.

[@SloGN]

The biggest problem I have encountered with the Four barrel TBI style injection units is the type of intake it’s bolted to. The fuel injection unit tends to like a open plenum style intake. If using a dual plane intake the divider wall needs to be machined down. The engine masters did a episode on this . Check it out! Now I still use and tune carbs. I don’t know near as much about tuning them as efi. But I have mostly worked on efi .

[@albertgaspar627]

thanks for making this point! it's quite important. one of the problems with aftermarket TBI is they try to be a single solution to many engine setups, and that's going to lead to issues.

[@GorillaCookies]

I've ran a few different Holleys, a couple different Edelbrock avs carbs and a Edelbrock AVS2 on my 401 powered 74 Jeep CJ5. All new carburetors. And The best it ran with a carburetor was by far the Edelbrock AVS2 . I switched to Holley Sniper EFI and it's never had more power , ran smoother or been better off road. I've had zero problems since installing it 2 years ago. And it's running better than its ever ran before the EFI . In fact it was still getting better and better after 3 months of installing it. It's been a game changer . Better mileage and performance today than it ever got with a carb. I will admit that the Edelbrock AVS2 had excellent throttle Response and mileage as far as carburetors go. Best carburetor performance as far as power was with a Holley 650 cfm center squirter but it wouldn't stay in tune and was a leaking pig after just a couple months of use. The Holley Sniper is excellent if installed correctly. The directions aren't difficult to follow if one can read. Best thing I've ever bought and installed in my Jeep

[@jeffjohnon4223]

The old Edelbrocks really rip if you put in the HP needle and seat and the performance accelerator pump, put a 4 hole spacer under the carb to really boost the signal, then use a velocity stack type air cleaner or one of those triangle Edelbrock air cleaners.

[@flinch622]

I like the look of velocity stacks on some rides but... it's show. They can [in a few extreme cases] work against you at the top end: air bleeds find themselves referenced to something less than atmospheric pressure - depends on the carb and surface area of filters. Would I give up 500 rpm and 2hp on a street car? Yeah - wtf.

[@jeffjohnon4223]

@@flinch622 I'm only talking about a regular Edelbrock carb, not anything with air bleeds. As far as a velocity stack, it doesn't have to be very high, like the triangle air cleaner, as long as the air comes in from the top and flows downhill into the carb. Saying that makes no difference is like saying head porting makes no difference. The speed of air coming into a carb is massive, directing it is essential, especially on a Edelbrock carb.

[@pmotorsports8276]

Triangle air cleaner ?😋🤣😆😅😂 car/carb fire with first backfire. Pieces drop in carb when filter ages

[@jeffjohnon4223]

@@pmotorsports8276 Ok the "Pro Flo" air cleaner. If your car is backfiring through the carb you are not ready for a air cleaner yet, as far as pieces falling into the motor with age, hmm,do you leave your air cleaner on for decades until it desolves? Yeah those guys at Edelbrock don't know anything about what air cleaners work on the carbs they make.

[@davidkeeton6716]

The new Edelbrock 4150 you described sounded an awful lot like the Speed Demon 850 I bought 20 years ago. It had all the features you talked about except the mount for the TPS. It may have had that, but I didn't need it or look for the mounting bosses. Anyway it sounds good. I have a 1413 Edelbrock 800 that I am just now getting started with on this 401 FE Ford build. Promaxx heads, Howards hydraulic roller, 10:1 DSS forged pistons. Building anything other that a SBC, BBC or SBF, you have to wait FOREVER for parts. I'm over a year into this build thanks to having to do it again because of a failed Comp Cams flat tappet cam and lifters. I'm in that club now. Thanks Tony, great video as always.

[@alfredotrivinopineiro2870]

Never had Edelbrock, yet hear good things about them. Our '1985 Dodge B350 one ton van has the Rochester Quadrajet and works great. Cold start, one pump and three seconds of ignition and boom! Just wait 30 seconds for the oil and fluids to pump around and good to go. Warm/hot starts are immediately starts. Fuel lines close to engine have heat shields around to protect some from vapor lock. So no reason for EFI for us. Only thing we don't like much is the mechanical fuel pump. Any suggestions? Loooking into the Facet Cube 4-7 psi electrical fuel pump, just don't see any good mounting spot near and low at the fuel tank.

[@Spudderr]

Hopefully summit keeps producing their holley 4010 copy. I really like it for a mild daily driver. Annular boosters, top plate gasket for no leaks and all holley interchangeable parts. They have been my go to for years and have only had one fail when the shafts wallered the body out and started leaking no matter what I did. Excited to see 4150s continue to be modernized though

[@calebkey2050]

I really hope Edelbrock cooks up a vacuum secondary version one day. Even on a daily driver, I’m a Holley guy through and through. I’d snap up a vacuum Eddy 4150 in an INSTANT!!

[@dawnmclees]

Aren’t the vacuum ones 4160??

[@calebkey2050]

@@dawnmclees Nope, a 4150 is just a carb that has a metering block on the secondaries, as opposed to a metering plate on a 4160. Both styles come in a very wide variety of flavors. The HolIey that I run on my car currently is a 600cfm vac. secondary 4150 If you look closely at the old crusty Holley “4150” Tony has in this vid, you’ll see it’s actually a 4160.

Nice report. I've been experiencing an issue that had me scratching my head. After a 5 minute run, then a shut down, 10 minutes, and restart, flooding. I found a video that showed gasoline boiling at 170, surrounded by water. Well found my issue. I use 750 Holleys on my big block Fords. My boat has no issues- 150 deg. My F100 gained 1 quart of oil in 4 months. When I turn the engine off it raises temp around 190. Lower float level didn't seem to help, but a fiber spacer plate did. Arizona summer kind of brought it back. Seems like something is trying to move us to efi. I'm trying a 2brl to see if 1 fuel bowl means less fuel. 3 750's all did the same thing... Like you said, with a 350 cm holley, its like of like running my Edlebrock 600... but after 40 years I don't need to be running that hard. Thanks for the info.

[@pauberrymon5892]

Great video and info UncleTony, I have 1 of those Carter/AFB Carbs, on my old 318 Poly with the front sit screw. Its 1 of the best long lasting carbs I have ever owned. They are tough as a hammer just like you put it.

[@rotaxtwin]

For the most part I agree with everything you said here regarding the Edelbrock AFB/AVS clones. The fact that they only make the air valve secondary is very limiting. I look forward to their new carburetors because I have always liked the way Edelbrock rolled as a business. They test the snot out of everything they offer, and they support it. Too see them beat Holley at their own game does not surprise me at all. They have their shit together and Holley should have been improving the 4150 since the 50s, not just sitting on them with the minor improvements that they did.

The AFB comp carbs were way better then the early Edelbrock carbs, we did the switch on 2 drag cars that had comp series AFBs and both went about 3 tenths slower, and jetting didn't help, the newer ones seemed better.

[@flaircraft]

I've been very happy with my new Thermoquad (er, I mean Street Demon). It takes the latest and greatest factory carburetor design before the OEMs started f*cking with the designs to meet government standards, and then makes evolutionary improvements to it. It's been perfectly reliable, gives good fuel economy, smooth idle, flows enough to make the horsepower, and is far simpler and cheaper to install than an EFI setup. And, tuning the mixture with screws is so much easier and quicker than having to pull out your computer or smartphone and hook it up to the EFI and fuss with all the numbers and buttons. In contrast, I put an aftermarket computer on my 5.2 Magnum engine when I did a 3.9-5.2 swap; even after 3 years of screwing with it, the damn engine STILL doesn't run for 5h!t. The cost to buy an aftermarket computer and harness was as much as it would have cost me to just buy the carburetor swap components (carb, intake, distributor and fuel pressure regulator). The time it took to build the EFI computer from the kit, custom build the wiring harness, and install the parts was the same as it would have been for me to pull the EFI intake and put the carb'd one on. So, for equal time and money, I could either have something that's a PITA to tune and still doesn't work quite right after 3 years of trying - OR could have a setup that would have just worked right out of the box.

[@darlenegeorgeboyd8493]

I removed the factory throttle body injection form my 1990 Suburban. Replaced it with an Edelbrock 1906 carburetor. MUCH better acceleration and driveability with no loss of miles per gallon. I did change the metering rods to slightly smaller diameter ones.

I’ve personally installed dozens of sniper units here in northern Va where the weather changes drastically all the time. Never ONCE have I encountered an issue. I’ve also corrected or fixed the install of at least 20 systems that other shops or “installers” did simply because they can’t read instructions or think they are smarter than Holley. I love when people want to blame the brand instead of the installers and I’m tired of dinosaurs shitting on tech they refuse to accept for childish reasons. My point is if it doesn’t perform to your expectations it’s not always the products fault. Most of the time it’s incorrect fuel supply or ststem install or tune files set up very far from correct. I also love carburetors and know they have a place and I’m thrilled to see them still growing and getting better. There’s a lot of people now that want an old school hot rod that can’t tune or have the time to play with jetting their carb every few weeks or want to be under the hood at all. They want to drive their car and enjoy it. That’s where the sniper is ideal. My customers that don’t mind an occasional jetting or squirter change can rock an HP 4150 and love it. Both have their place. Period. Don’t shit on things you don’t 100% understand because you don’t like progression.

I’ve noticed the last few years that carbs for small gas engines have actually gotten cheap compared to everything else in the world. Between all my chainsaws and lawnmowers and 4 wheelers I’ve probably got a dozen or more small engines with carbs. I normally just order up a carb kit when something starts giving me trouble but lately as I search around I can find complete whole brand new ready to go carbs for very little more than the cost of a rebuild kit. It’s like they’re just trying to get rid of them all.

And how about those modern plastic carburetors? I've done a B-string rebuild on a few of them now, but was surprised at the first one I came acrossed. You can still get a car battery for less than $60 at Walmart! Today I got a new group 35 for $57! They had a better one for $149, but I've had good luck with their cheap batteries. My previous one lasted six years! O'Reillys wanted like $200 minimum I believe.

On my performance cars I worked with Holley carbs for nearly 10 years , never was I satisfied with all categories of performance : WOT , mid-range , transition , idle , vacuum , fuel economy , leaks and ease of working on them ! For PURE quarter mile the Holley was king , but only by a small margin ! The AFB was a great carb for EVERYTHING except pure acceleration in my experience !

[@richardprice5978]

probably non it's just easier to change the 273 intake manifold or adapters/fabricated a new one or modify the old manifold to fit , in the long run i think the dominator pattern/carb is going to be the winner of Darwin awards with the holly's 4500 being 2 place or at least for 🇺🇸 car's/down draft carbs that or EFI wins completely out and gets 1st place
