Single plane vs dual plane intake

I agree. Trying to eek out every last ounce of power/torque that might be in an engine means that there are trade offs. Tire height, rear gears, vehicle weight, cubic inches, camshaft, compression ratio, intended use of the car, etc..... You have to look at the entire picture to make decisions that work in harmony with each other.

Doing that is a lifelong process and you find the end of the fun real quick. That's why I always say "pick one and go" when people ask for a cam recommendation and everybody is telling them the same thing within a few degrees and lift range. Once it gets narrowed down "that much" a dyno is the only tool that will tell the difference and we don't all have one of those in the back pocket. lol

That is not a small block but it is a 600 horse daily driven 12 valve Cummins that my son and I put together last year

It took me a year to study up on that one

Sounds like me when I decided to build an early Hemi. I did over a year's worth of research before I even found one. They are quite interesting engines.

AND!!!! AND!!!!!

On top of it all, the OP is being insistent on a Definitive answer when there is none because it such a flexible option. We also have ZERO information about HIS particular combination which would be an extremely helpful.

As usual. LOL
 
RRR. I’ve never even seen one of those. Read a lot about them and a lot of the old timers where I live have plenty of stories about them.

4,6,3, and 7 ? 7? It all depends on how your carb is tuned.

Mis typed. Meant 4635
The shorter ones ram less maybe, maybe runner shape/sharp bends. Regardless, it needs to go on the bench and be tuned.

Your results might vary. 340/360 intakes.

Went with a 340 victor single plane here. 292/508 cam and 3.91's out back. Hope it will be good. 9.5" FTI 3400-3600 stall converter. So I think it'll be good to go. Fingers crossed.:eek:

Why would a stroker have to be a reason to use a dual quad tunnel ram? :thumbsup: :lol:

I started out with the tunnel ram on my stock 318 no matter how much tar and Feathers this forum through at me..
You could hear a pin drop when I said I went a half second quicker in the quarter mile..

This is why I have this question. The jump in cubes. Would it not need more volume. But most here have said that the low end will suffer. Which puts you back to the dual plane(air gap just because I have one). Let’s ask another ? Then. What would be the best single plane intake for a stroker motor that is 85% street. Maybe there is no such animal.

Thanks for all the replies by the way

Trust me if you get a stroke he won't be suffering from low end problems. The only thing that will be suffering are the back tires...

That one works good once you deep port match it and do some plenum work at the port dividers. Lol
Stock heads and it works bitchin.hehe

What do you do in the plenum?

First off make sure it's sized for the gasket and or the barrels cuz most of the time they're not quite there and then blend down below the flange a lil. I know it's not fixing it completely or bringing about the ultimate potential if only there was more material cast..but that's what you do when you're not a machine shop. Iq52 made a plenum insert, member? On an m1 perhaps or was it a super ..either way im saying you contour the entire induction system IF you want it all to work right.
Of course you can get lucky just bolting **** together like 60% of people and go on to tell stories of "that one motor" that ran like no other... lol ... bang.

I did this, still debating if rounding or "bull nosing"? the runners outer wall junctions would be worth it in my case. Doubt it will hurt, something to do at worst.

My dad used one on his 340 years back when he had it. He says it ran like taz on speed! He doesn't recall if he did any work to it. He does think he port matched it. It was on a 340 with a racer brown cam similiar to my 292 mopar cam.
