I remember from my days bracket racing that the 'B' Mopar engines had a distinctive sound that I always liked. The drag strip is the final dyno test,lol.

[@gristlepounder]

Mopar's have a unique sound because the exhaust valve is so close to the port exit than the others.

[@livewirebio-medical9082]

@@davenichols5156 My 440 6bbl RB factory motor would disagree with your "B motor makes more power than RB motor" post. I am a big fan of the 383, and the 400 B makes the best FACTORY BLOCK to use for a stroker build if block strength is the most important factor. I have a 572 being built (4.5" bore and stroke) but to avoid any block strength issues or cap walking, I am using a Bill Mitchell Products aluminum RB block w/4 bolt mains. Like the owner of this motor, I am using the Holley 3x2bbl "Six Pack" that came on my 70 V-Code Roadrunner, but the Indy ModMan intake ported to Max Wedge port size (Trick Flow 270s). The carbs have been modded with Promax parts for easier tuning.

[@tint661]

I was on a chat line the other day. A guy on there wanted to swap his modified Edelbrock carb for a stock Edelbrock carb. He said the guy he got his carb from had modified it and it was running rich. I told him about the Edelbrock kit you can buy at the local Advance Auto Parts, Summit Racing or Jegs. Who knows if he believes me, I told him they are easy carbs to change the metering on. Don't have to drain the gas to change the metering rods or springs. I have had some luck right out of the box also. I put an Edelbrock Performer and Edelbrock 650 Carb with an electric choke on a Dodge Truck with a 318. He said the cold start stumble stopped and it idled so well that with the stock muffler he sometimes tried to start the truck when the engine was already running. He was happy that on cold days he could just hop into the truck, start it up and go with out sitting for a couple of minutes until it warmed up.

[@pjimmbojimmbo1990]

About 30 yrs ago, my cousin dropped one of those setups on a 383 he had in a Dart. I watched him run it up and down the Alley, of all places, as he was complaining it wasn't using all 8 throats. I shook my my head, and discovered that one of the carbs had the Idle Mixture screws completely shut, and the linkage between the carbs was way out. Eventually he just used a Single 4bbl and was much happier

Back in the day I had a 4-speed 70 Hemi Cuda and I ran two Carter 750 cfm competition series carbs most of the time wile on the street. The motor had Cylinder Head Service modified heads, roller cam, and12.5 compression. It was an old SS/D motor that was run in a SS car out of Ohio. I used a stock intake for the street that had been extrude-a-honed and the car ran strong with no breakage besides valve springs from time to time. Love the videos Nick keep it up.

[@396375a]

I always had SBC or BBC in my cars, but seeing how easy changing an intake is on a Mopar big block makes me wish I could go back in time and gone to the DARK (Mopar) side. I use to dread putting distributor back in if I was alone, so much easier with two people. But Mopar's look so much easier to work on, and similar power too.

That intake manifold was first used on the 1958 350 cu. in. Fury. It’s funny that the 350 turned into the 383, and eventually the 400, and not a BowTie to be seen.

[@dinadaughtry8993]

Best thing is that they are the same stroke and the 383had a Forged crank that was pilot bearing ready to go in the 400s big bore to really handle the RPM, but of course a stroker kit makes that point moot and it being a short deck saves weight and room also a very strong block

[@mikestackhouse9001]

Another satisfying Dyno video Nick and George! That Carter "Strip Kit" takes me back. I had a 1978 Dodge Magnum that I swapped a smog 400 for a fresh 440 that had lots of goodies in it. Atop the stock HP intake manifold was a Carter Thermoquad. I used the strip kit to change jets and metering rods til I got the perfect seat of the pants launch from the 8-3/4 posi rear end. No Dyno back then. It ran well and the Thermoquad had the phenolic base that kept the fuel cooler on hot days. No thermal lock ups.

[@mitchburk5112]

Chrysler engineers of that era understood manifolds. The long cross rams with the carbs on the fender liners were done for torque not so much horsepower. Was designed to give heavy cars like Chrysler 300 letter cars better acceleration. When they started putting the big block in the lighter Dodge and Plymouth models for drag racing with the Max wedge in 62 they went to the short ram for better top end performance.

[@loboheeler]

Yep, the long cross ram intake was designed for mid-range torque. Friend of mine had a 1962(?) Dodge Polara with that 413 version. It would push you back in the seat with a 60 MPH full throttle kickdown.

[@BuzzLOLOL]

Chrysler siamesed the outer ends of the long ram tubes for higher RPMs HP in the race engines...

[@vipottaja]

I used the same intake in a mild "Christine clone" build up based on a 400 block. Nothing special there, 440 source heads homeported, comp 21-227-4 cam with factory rockers and 1 3/4" primary hedman headers with 3" exhaust and mufflers. The intake was modified some, it was opened under the carbs cutting the four hole portion out and curved to the ports, making the plenum a bit higher. And then tapered four hole 1/2" plywood spacers were used under the carbs. It surprised me, making the best power of similar build ups I have done with that cam and with different intake manifolds, RPM, Torker2 etc. Close to 540 hp.

[@jimjungle1397]

Originally Edelbrock made them for the 440, but not for the 383. With the stroker kits becoming popular, there was a demand for a low block version. Edelbrock claims the low block Performer RPM has improvements over the 440 version, because they had learned more about the intakes by the time they came out with the low block version.

Goooood EVENING!!!! Ha, there’s a switch for ya!!!! 😀 Great video, Nick and George!!!! It is interesting that the dual quad manifold didn’t lose THAT much performance: I was thinking it probably has slightly smaller passages, therefore mixture velocity is a little higher, and having two carbs sorta takes advantage of that.

The top camera angle watching those carbs pull fuel is just beautiful, that motor definitely liked the longer intake runners. That was a lot of power to give up from the dual quads.

[@Welcometofacsistube]

Had an original offy dual 4 barrel spread bore intake for a b engine from the 70's that was never on an engine. Put 2 thermoquads on it but never did get to put it on an engine. Some guy gave me a offer o couldn't refuse for it. Still kicking myself

[@OlSgtLove]

I remember those intake setups . They were really nice intakes . Had a friend with one in an 68 Chevrolet Nova ....Ran like a scolded Dog ....Those were the days !!!!

[@ThePaulv12]

This particular intake Nick was designed to compensate for the fact that at the time there were no large CFM 4bbl carbs yet. The only easy way to get around the problem back then was to run 2x 4bbs. IIRC this intake was set up to run 2x WCFBs. The adapter plates on the intake point to that. Tuning dual quads for the street with a dual plane dual quad intake is a bit of a dark art these days but they can be made to work. Really what I feel you need to get them to work is a single plane dual quad intake of modern design. A pair of those Edelbrock Thunder carbs are actually better than true Carter AVS carbs were and certainly more adaptable than the Carter/Edelbrock AFB for dual quad. Over a single 4bbl the effort to get the dual quad to similar power is high and the rewards probably not worth the effort for most. On a 440 I got excellent results from a dual quad Edelbrock CH-28 intake with AFBs but it took a lot of mucking around and it only made maybe 8hp more than an 850DP, a well modded Thermoquad on two single quad intakes ie a Torker II intake and a M1 single plane. The TQ on the Torker was fantastic combo. It was just so simple and easy with little effort to get power from the TQ but I digress. Back to my dual quad adventure, to me it was well worth the effort but ideally as mentioned, you need a single plane dual quad like you can now buy for a Gen 2 Hemi from Edelbrock but none is made for the Wedge. I did get a bit more power with a dual quad dual plane intake with 2x 500 CFM Edelbrock AFBs but I wouldn't recommend it unless you like a challenge - which I do. I really learnt the limitations of the AFB style for dual quad and at the time wanted something like a hybrid of a TQ and and AVS. The Edelbrock Thunder wasn't born yet at that time and it is indeed the hybrid design you need for dual quad tuning ease. I found for my setup opening the primaries together worked really well but I tuned it for that after much trial and error with the staged arrangement. Fuel economy was still acceptable when it was all properly set up that way. Re low deck dual quad intakes, unfortunately except for the rare Edelbrock cross ram there isn't much in the performance stakes for the low deck dual quad aficionado these days. Part of the dual quad tuning is recognizing Venturi vacuum at WOT is halved over 8 barrels vs 4. There are two philosophies and both seem to work. One way is 2x small carbs because it pulls a stronger vac signal thereby compensating for the Venturi vacuum drop over a single 4bbl, the other is 2x large carbs with big jets to compensate for the reduced Venturi vacuum signal over a single 4bbl.

[@gitchermotrrunnin]

I believe you said the 2x4 bbl manifold was a single plane, and it is low profile. My understanding was single plane manifolds are best for hi-rpm performance as opposed to the dual plane which is more for street use. The Performer RPM manifold is light years ahead in design so it is better all around. The Desoto Adventurer cars were the top line Desotos and they always had hi-po engines and the 1959 Adventurer had a 350hp 383 with the 2x4 bbl set up. I have photos.

Yes, that dual 4 has very very short runners, which makes for top end HP or at the very least extended RPM range.

I was talking to my friend about 2 4s on a BBC he said exactly what you said. Very informative video

[@scottkovacs7634]

You can tell that Nick is in his happy place.

[@davidwood1923]

I Enjoyed Your Video... Thanks for Sharing

[@nativenation3296]

I like the first setup, single quad 👌

[@douglasb9105]

HAPPY BIRTHDAY, BLINKIE!!! You're catching up to me!

[@blinkie1523]

Thank you Douglas B

[@bullast2046]

I appreciate the fact Nick puts the effort into squeezing all out of the dual quad he can even though HE KNOWS that single carb dominates

[@chriscatarcio2983]

Tunnel ram rules. Over a single four.

[@BuzzLOLOL]

You mean high rise dual plane single carb. intake...

[@jimkillen1065]

I think that this is a example of what a set of cylinder heads not sure how good they are , I noticed they had some port matching or I think so . At any rate I was told a long time ago you can run more compression on aluminum heads . The cylinder heads here support more horse power or that my option. I rather have a really good set of heads and a little smaller cam . But still carry out and not lay over . Years ago I had heard of the b block and rb crank build . May be the bigger bore pulls harder on the cylinder heads . I appreciate the videos

Had a 413 back in the day with the dual four setup. The one with those odd football shaped air filters. It was pretty fast when viewed from the HiPo stock POV of 1962. At the time, I didn't know enough to try and tweak the AFBs on it. About ten years later when I started fooling around with it after being in the Army, my quarter mile times improved with a single four aftermarket manifold and a big Holley (780 I think... might have been in the 800cfm range). Those dual fours sure looked cool, though!

[@chrismadaj8751]

keep it up Nick and George you doing a great job and the rest of the crew most of all God bless

[@NicksGarage]

Thank you! Will do!

[@karaDee2363]

I'm impressed that this engine makes that much power

[@tatdexter2334]

Sounds like someone found some ancient alien tech. ;) - good to see that

[@jimmyturbeville8753]

rock and roll Nick you are the mopar man i love those big blocks thanks for sharing

[@johnfitcheard7112]

I wonder if a modern dual quad set up make any difference. Very respectful power even after the loss!

[@ecleveland1]

It might sound strange to some but sometimes it's about the "Coolness" factor instead of getting every last HP out of an engine. You have to admit that dual quad set up sitting in the car looks "Cool"!!

[@StrokedGT]

Yup that’s why I’m going with the same intake, you’re never going to be the fastest out there anyway!

[@BuzzLOLOL]

Even kewler in a '62 Dodge!

[@yianniyianni8158]

Bravo Nickos good job levendi !!!

Nick I love your shows

[@kevinwoolmer5478]

Thanks guys,another great show

[@NicksGarage]

Glad you enjoyed it, Kevin!

[@v1-vr-rotatev2-vy_vx31]

Totally cool,lots of fun.

[@Cletrac305]

Theres more in it! Never surprised by what the old guys knew! I always found those older 383s and 413s would spank later engines including 6bbls That intake on a '59 desoto 383 was 350 hp. Roadrunner was only 335! I have ran this intake (mine was cast in 1957) on 383s and 440s with spacers along with alot of other stock and aftermarket multiple carb setups. I never use progressive linkages (except 6bbl) I have found that non airdoor early afbs (2797s) bored out for the new larger accelerator pumps and with larger needle valves worked the best partly due to the longer booster venturis. I keep a logbook of jet and rod areas for all aspects of tuning including modifications to intermediate tubes and air bleeds rather than size because .010 takes more meat out of a large jet than a small one. Then log the the primary side, high and low rod, the secondary side, and totals so I knew exactly how to add to the top or bottom without affecting the total. I gasket matched it and cleaned up the inside radiuses to balance port flow, blocked crossover, milled the 8 holes into 4 oblong retaining the center divider and made 1" aluminum carb spacers to match. The bottoms of the carb holes were relieved in the direction that would direct the fuel to the rear and front ports. I am positive that set up like that it would easily beat the edelbrock from 5500 to 6500. But loose bottom end torque. I would suspect that due to lower cyl pressure at low rpm it may want more timing No one who drove it on syncronized linkage wanted a single 4 back! All my cars were C bodies and my only transportation year round in Northern Indiana (4.10 to 5.13 gears) then to drag strips on weekends no breakages in 20 yrs! BTW my absolute favorite intake is long rams with 2 thermoquads I have a TF bellhousing that was split when they flashed past the rev limiter to 7500 rpm! Properly set up they will do that on a mild 383 in high gear at 120mph in a newport! Fun to go back and see black marks where they come in every 800 rpm! Tried to catch it by shifting into 3rd that was a 1959 imperial 413 with a special cam and reworked 4 bolt VC (according to "common knowledge" those are all junk right?) "509" heads which i have found to be superior to 516 and 906s. later cup style freeze plug "324s" are also better. My wife and I really love your show it has been very relaxing during hard times. After my brain tumor disabled me, and my father passed from one I had to get rid of 130+ engines and over 250 heads including every mopar B series casting made save some max wedges from the 350 on up including -3 413s. And 361s even some left hand rotation marine engines(the cranks are different at the rear seal knurling) Keep up the good work!

[@romper4444]

Wow that's a lot to take in, nice work! Now I need to go absorb all that

[@Sonic30ss]

Glad you did this test, I have one of those dual quad manifolds on the shelf. Been wondering how it would compare to a modern one. All in all pretty good, wonder if some 1 1/2”- 2” 4 hole spacers would help?

[@craigg4925]

yeah, I just asked that question, do you know that HP gain for spacers? I'm thinking it something like 3% HP per inch but just can't remember.

[@dinadaughtry8993]

@@craigg4925 suppose it depends on material and design of the spacers,I would like the answer to that question also

[@ottokerkhofs6762]

Hey i see a nice riviera in your shop, nice. I have a 68 riviera

[@pappy017]

Pretty impressive with the old school intake!! Have a Great week Mr Nick!! Missed Ya this morning. Had my coffee in my Nick's Garage mug, without Ya :(

[@NicksGarage]

Sorry, Pappy. We know you were aways a loyal morning viewer.

[@pappy017]

Thanks Mr Nick!! I hope to be able to look you up, some day!! I don't cross the "border" too often. If I do, you'll be my First stop! Enjoy Every Day!! If you're able to make the trip down to Columbus for the Mopar Nationals, I'll see ya there!!
