[@mynameis63]

Based on the tight EGT spread between cylinders...perhaps the most reliable route for a lil street engine that makes good power...go EFI. Yes more maximum power using a Carb; however, the wide spread of EGT suggests less long term reliability. Pretty interesting stuff. I considered going carb when I built my 6.1...but wanted to make good long term power. I've now put nearly 50,000 miles on this engine in 5 years. Stock gen 4 bottom end, 30 over flat tops, split profile BTR .593/.631"lift cam ...Trickflow 225X heads that flow 348 cfm at .600 92mm throttle body , 40lb injectors and 1 7/8" long tube headers. Black x racing built me a stout 4l60E with 3600 rpm stall converter , and 3:73 rear gear. Pretty tame compared to what the boys run, but runs strong...smacked lotsa asses with it...often get well into the 20s for mpg, and all I've ever done to it is Uncle Buckos favorite thing...maintenance.

The engine doesn't care *that* much about the egt spread. You'd lose it if you saw the egt spread on a Continental O-470, and your life literally depends on the reliability of one of those.

[@enigmacamaro]

I 100% agree with you, the spacer with a single plane would work quite nicely on that engine. what a lot of people don't understand is whether it's a small block, big block, ls, ford, or even dodge. you have to remember that they are just basically big air pumps. With that it's hard to knock on a stock engine with a cam making over 400. got to love that flow from those ls heads.

[@alanmeyers3957]

They are not air pumps, at all.

[@enigmacamaro]

@@alanmeyers3957 explain to me how they are not. They suck air (and fuel) in, compress it, power stroke, and then press air (exhaust) out.

[@horsefly1020]

He can't explain it.​@@enigmacamaro

[@ShawnGilbert1967]

Look up the term volumetric efficiency ( hint it's how the efi works and why they are air pumps)...with overlap and headers for scavenging you actually can get more than 100% volumetric efficiency and it all depends on baro at intake stroke I just cant understand how people, though it's cliche, can't see engines as air movers...everything is rated that way including gasp port cfm....

Loved you throwing the E85 carb on and showing the numbers... Crazy that the E85 made so much more power than the gas on an engine with just 9.5:1 compression..... I think a set of flat tops to bring it to 11:1 with the same combo dialed in it would see 450hp and 410ft lbs.... I love these videos of the in depth carb tuning😢

[@jeraldhite9744]

Super interesting!! Thank You. Good to see Bob doing well.

[@darrensaunders3694]

Love the content! I use a msd 6014 box on my carbureted ls engines. The key is time them like a standard small block! Just because you have coil on plug does not make a difference. Then once its done you can do individual cylinder timing and even create a timeing curve for drive ability.

[@ShawnGilbert1967]

You would time them like the combustion chamber efficiency dictates thru every standard practice to find optimal timing for a given cylinder head design and induction package.... You go tossing sbc timing at SOME ls designs especially higher compression ones on stock pistons and have a bucket close... In his example what showed little gain at 33 via EFI needed 36 to replicate with the increased droplet size ( there are other factors involved too ), just take an LS engine that has knock past 24 degrees and toss 36-37 locked out in it at peak torque LOL bring a broom....

MY FAVORITE GARAGE CHANNEL ! 😁👍🏼 Bill I have a 5.3L LS aka: 327 Ci and I love it. Chevy made their small blocks last a lot longer and get 3-4X more miles outta them before a rebuild after they came up with the LS. I’m a old school guy from the 60’s 70’s & 80’s But Chevy took their engines to the next level with the LS as far as ENDURANCE & LONGEVITY goes. I was also hesitant to give the LS a try but once I did I really like the LS 5.3L & the 5.7L small Block LS’s they’re great engines.

[@ShawnGilbert1967]

I agree for the most part but I've seen several I mean several 350 Vortec engines over 300k in trucks ect.... Maybe 1968 tech but there is not inherent problem with the geometry of the sbc when done with modern metallurgy and build practices...id postulate drop the ring size to as thin as LS and there ya go... Now stock block isn't gonna hold the power the skirted crank LS will hell no...but endurance shouldn't be an issue with proper fueling and cooling...

[@sanger440]

I love back to back tests. I remember decades ago Pat Musi was an early adopter of EFI. His race engines with carbs always made more peak HP than EFI. But he proved EFI was faster on the track than his carb combos because EFI made more power throughout the power band (under the curve) . Cool video, thanks.

[@TheSargeGX43]

Great video. Reverified what I already knew, but it’s good for the younger generation to see it on the Dyno. Carburetors make more power than EFI, always have and always will! I would love to see few pulls with a 750 and a 850 on gas just to see how much power they would make vs the 950 on the 5.3.

[@ldnwholesale8552]

I had someone telling me recently I need fool injection on my road racecar. Asked why? It will make more power, as this just proved it will make less power. A passenger intake may make some more with efi,, but a single plane will make a LOT more with a carby. As will the right size carburettor also. I am happy with the efi on my road cars, start ok, drive ok and reasonably economical. But power? No.

@JBAutomotive794 I'm not certain on fuel tech ( but I mean Bob should invest in a carb retrofit tps many sell them, ive used them for carb 4l80e applications) but just off the top of my head wouldn't speed density go pure map... Though TPS is probably telling the ecu that it's at idle... For a bush work around a $12 oriellys ls tps plugged in, scaled, then laid to 100% walk out cell? Just for that day.... But yea a retrofit carb TPS would probably be useful there...could go carb to efi testing and selling.....

[@petemcpeterson6205]

Holdner had similar results. Made the most peak power with a carb. He made more power at lower rpm with efi but was using the FAST intake.

[@travispeoples]

I don't have anything against carbureators... but I wouldn't give up the efi for a little bit of power. Drive ability... instant tuning corrections for changes in conditions... fuel economy... engine longevity... the reason manufacturers have gone away from carbureation isn't due to lack of skill or user ability.... it's just simply hands down better. I have a carbureated hot rod and a fuel injected hot rod, and I love them both. Tinkering on both is a lot of fun.

[@justinhromek73]

I’m not in to changing jetting, accelerator pumps every time the weather changes. My Edelbrock pro Flo on my 406 is maintenance free for the most part and self corrects for any change of altitude/weather conditions. If there is any loss of hp with efi it would be minimal, benefits outweigh any negatives in my opinion

[@wydopnthrtl]

100% true. For a street car and yr round operation.... FI w/a feedback system cannot be beat. On a INDOOR dyno.. and considering costs... a carb might inch out a FI. But... my engine is in a car... and I drive at part throttle 99% of the time.

I can watch people testing on a dyno forever and never get tired of it! Hence why engine masters is my favorite show! And no matter how many I've seen, a carburetor always sqeaks out a few more horsepower than efi everytime! And now with todays electronics you can do anything with a carb as you can with efi except for fuel tables, which you really don't need to worry about with a carb, it is what it is.

Great video Bill! I have a 13 Silverado with the same 5.3 with a Procharger and a couple bolt ons and last time on the Dyno it made 479hp to the wheels. Great little motor. Actually I have been on Big Chief’s discord since he started it and he has given me tons of advice and information on cam options and some other things for this motor. I’m your age so I love old school SBC but I have had my truck since new and I have grown to love these little LS 5.3.

SBC should hold 490whp just fine, I suspect if your truck had a vortec 350 in it which also go 300k miles for that long you would be fond of it as well... I don't think most would say LS isn't superior, just at some levels not required depending on goals

Think a 5.3l LS is great for torque shit unchoke a gen 5 LT with a small cam and headers...

@@ShawnGilbert1967 I have a 1 ton Square body with its original 454 and it is a great motor even stock. What impressed me with the 5.3 is the power it makes for its size.

I'm just saying it's mainly heads...get some 15 degree heads on a SBC ( or hell 18x like many ran that used the 24 valve train) and there isn't that much difference below the max power of the stock block... Then the reason why the LT Gen 5 runs better is the 11 degree ( vs my ls7 12 degree ) valve angle with GDI.... I'm not putting LS down at all its just that the over hyping has driven them up to not quite the deal they were or even close and actually ironically made room for the same money to make BIG power NA on say BBC...I paid more for my LS7 heads than I did for fully ported AFR BBC heads flowing 420cfm lol....its NUTS half the aluminum.... It's a good time to be a gear head but damn 4l80e are getting harder to find and im not having anything I can't drive in....I got one spare left after I let a friend have one....remember when they were $100 a core and now it's 1000 for a builder haha nuts

GOOD JOB, most people do not know max Hp, Carb vs Fi is very similar but for the record where Fi shines a carb is great at low and high-speed mid-range as you know can be a compromise, then tuneability for individual cylinders, Fi gives you that ability to move your powerband around much easier and for those looking for milage and ease of tuning the computer is just hard to beat, the time it takes and not getting your hands dirty. Now I am a carb guy ran them for years in off road racing no floats, check valves, #4 line on the float bowls, full flow system, regulator on the return line and it works much like fuel injection it will not stumble in bumps or hard braking but its is touchy to set up.
