You need to modify a 4 hole,..2 inch tall spacer by ,leaving the holes alone on the drivers side, but cut out the divider between the holes on the pass. Side so that it looks like an oval race track, this equals out both plenum sizes.will need slightly more jet. With jet change and this mod, honestly, my 406, with air gap dart 200s, with 2.05s .654 lift, ft. Sounded different, and went up 20 HP. Dyno man said he had not seen this .

Not always. On a 440 Mopar, I put a Carter TQ on a Torker II with quite a lot of blending (I was committed) and the results exceptional. For example the off idle throttle response was brutal. Now I played around with a few intakes including an M1 single plane, and a MP dual plane both with an 850DP and the Torker + TQ was the pick. It howled up top, had awesome midrange in fact the best of the lot and the throttle response fantastic. Afgain the off idle punch was hilarious - you wouldn't think from a single plane but sometimes they work well. Torker II's were known to be pretty good on BB Mopars though.

With only basic tuning it ran low 11s @ 120 in a 3500# Duster and it was totally streetable. Exellent throttle response and and torque and it pulled hard to 6500 rpm.

I installed the Holly.. all it took was a kick the choke on and the engine would fire instantly.. never had any more starting problems after .

Mr. Vizard; this has been a wonderful video for me to not just watch, but also to learn about tips for the BBC two plane manifold. I just recently built a 454 and it is now 496 that went into my 1978 K20 Suburban. I am going to be pulling trailers and also doing off road driving with it. I went with a Wiend dual plane and a Quadra jet carburetor (partly because I am on a very restricted budget as a Disabled Vet). I then added a one-inch spacer that mimicked the carb outlets (two holes for each side. I also smoothed out the crossover gap for better balancing (that was what we called it when I was learning to do mechanics) of the cylinders. I am very interested to hear more about your work on the two-plane manifold as I would like to optimize it as much as possible. I also plan to put a Thermo-Quad on in place of the Q-jet as I think it will provide better atomization and flow. I will be looking forward to seeing the rest of this series. God Bless you and all the work you do to help the less fortunate ones to get the best from the equipment that they have.

On my mildly built AMC 360 powered CJ5 I port match my Edelbrock performer intake, reduced the divider and added a 1" phenolic carb spacer. I then added a brand new Edelbrock AVS2 carburetor. I chose the AVS2 carb for its drivability and possible added fuel economy because my CJ5 inevitably had become my daily driver simply out of enjoyment of driving it. But the performance increase over a non modified Performer intake without a spacer and with a excellent working AVS carb of the same CFM is shocking to me. I knew there would be some increase understanding the physics and operation of Internal combustion engines and the different flow characteristics between single and dual plane intake manifolds. But I didnt expect the performance increase to be as substantial as it is. It's easily noticed in the midrange and upper range of RPM . I would surmise its gained a measurable minimum of at least 15 maybe 20 hp at peak rpm and a easy 10 to 15 maybe on average hp throughout the 2000-5500 range . The bottom end while not losing any power seems to have a bit high peak for torque production allowing for more torque across a broader range of RPM. The next improvement is going to be a increase in air intake at a much cooler temp by installing functional hood scoop of some type. Which should also aid in the cooling of the engine itself by adding cool air increase to the engine compartment as well. Just working that dual function design out on paper and trying to make it both function and look good.

The early design intakes had a sqaure corners in the ports purpose, to induce turbulence for mixing purposes as shown in countless early publications about manifold design. Remember they were factory intakes, designed to run smoothly by creating good atomization from that turbulence. Sure performance was compromised. But they were not stupid. Look at the Miller offy that dominated racing for uphteen years! When we didnt care about engine smoothness and focused in power, yes designs reflect that now.

I could see milling out the plenum of the manifold. And welding in another made from 1/4" and 1/2" aluminum plates, welded together. With extra weld to allow it to be milled and hand ground to appear as cast. A needle scaler can go a long way especially with a wire brush and some sand paper. Weld the floor into the manifold! In pieces first. So the porting can easily be done. The the top portion. It would be a great time to port the whole manifold. I wouldn't mind if the carburator flange area was about 1"-1.5" thicker than needed, (over where it ended up) so the manifold can be milled down if required. Possibly etch in lines in the dividers to allow them to be cut keeping the manifold performance near equal after being cut. Even tap the bolt holes extra deep. So nothing else needs modification! I love heavy modification of about anything. Especially engines! And engine parts. I wish I could get a job doing it. I need to learn some stuff. But I have ideas. And imagination. Can figure things out. Always worked on cars since I was a little kid! - id do it for about free, if I wasn't poor id pay to have a job like that! Have an AWESOME DAY, D.V. and everyone! ✌️

You, David, are a true 28:54 master of Research Engineering and very literate and well tea😊d. Should have a nickname for you, how about Sir Dyno? Would like to do a 289 c.i motor based on a Mercury 5.0 block with long rods. Would it be worthwhile? Also would like to do another one with a 351 Cleveland block, 302 crank, and long rods, basically the Boss 302 Ford should have built! Another one would be a 5.0 using a 9.2" block with Windsor heads and manifold. How would I sell a KZbin video to pay for parts, machine, and dyno? Love your decades of knowledge and would like your wisdom on these projects. Sorry for the loss of your daughter, an angel now.

I'm curious, have you ever experimented with vaporizing the gas so it runs on fumes to maximize it's use? I was thinking about a simpler way than Smokey's way, and perhaps better than running a bubbler. By running a stainless steel very fine mesh under a carb spacer, or the carb. sandwiched between two gaskets to help give the gas more surface area to evaporate from the temp and air passing through the carb before entering the manifold... if the mesh restricts, then just give it a shape to counter the restriction with more surface area, like how one can use a larger air cleaner to counter any restriction from the media.

Hello, What a boutique dual quad manifolds? I've always thought they were the best.

Dominator series 460 Edlebrock Performer manifold? And or BBC version Idle to 5,500 power band? Yes King David R&D fun - fun - fun If only we had the mini foundry set up to cast the carb base ourselves:) Then do some nice welding… O’ when it’s done Polish the entire outside finish:) Lots of flap wheeling and sand rolling:) Hand work too:) Anyone can buy expensive parts and bolt them together. But to properly do all the bowl work and area ruling on the cast iron heads… That’s the real test of the craftsmanship. Budget minded - Sleeper engines

Very interesting, I just bought the Hughes Airgap FI for my Jeep 5.9. Does it make sence to cut out the devider for Fuel injection? I know its not a race engine...

Hi David will be fitting a holley sniper on to a dual plane manifold and the general consensus is that you have remove some of the plenum divider to make them run well (hood clearance may be a problem with a spacer) can you shed some light on this and how to figure out how much I will have to remove from the plenum divider if i need/should have to make this modification.
