Intake Choice for 400/512 Stroker

-
If these are anything like the small block versions, it would probably be every bit as good or better than a TM6. Notice the lack of bolt intrusion on #3 and #6 runners. The old Weiand Xcellerator. This would be an earlier P/N without the Xcellerator name but it is otherwise identical to the later model.

And the TM6 for comparison

I'm running a weiand team g on my 440, cause I have it. It did have the bolt intrusion in the inside ports, but nothing a die grinder didn't fix.
From every comparison test with the team g in it that I have seen, it is not great manifold.
 
I would stick with a single plane to avoid the distribution issues that come with a dual plane intake.
The Holley street dominator intake will support 600hp at 500"+ no problem. That's a fact.
 
In my opinion, design alone torker isn't good for your application. 4 choke points where bolt mounting intrudes on the port, core shift is very bad on the few I've had.
The Edelbrock rpm would be my choice for your build. You can lower the divider in the plenum & pick up extra. The runners are nice and big for standard port.
Although it's a dual plane I'd say it would work.
There's other single planes that would do well also, just not the torker.
Probably trickflow intake best for 600 hp
 
The Trick Flow or Victor B intakes would no doubt provide the most all out power, but that whole under the stock hood thing probably negates those choices. But that Weiand I posted the pic of is one of their early funnel web designs. Lost's of plenum and runner volume with symmetrical runners that taper evenly to the flanges. They're soft on bottom end torque on most B engines, but work well on a stroker.

I like the Weiand Garrett talked about in post #26 or the Street Dominator. I believe either will be sufficient. Either one of those, or the Edelbrock RPM.
 
Any of the low deck Weiands I have seen have horrible bolt clearance intrusions on the runners

Yeah, they newer ones really suck. The earlier one I posted the pic of has none that going on. The stuff Phil Weiand help design up until his passing in 1978 was much better than the crap Holley turns out under his name. I’ve seen several cast at the Winters foundry. Even the better designed intakes like the action plus and the stealth dual planes are known for having core shift issues.

Three 'key' numbers are going to eliminate some intakes:
- 11.00 sec
- 512 ci
- 4000 lb
 
5? A catch 22-ish item maybe? IMO, the cam is small for a single plane intake. Though at 500+ cubes will it really matter?
Bewy nailed the big ones.

@Walker434 , did you find out or figure out what intake will fit under the hood nicely?
 
The 4.25 inch crank lets you get by with quite a bit of too much induction. Almost no such thing as too much manifold. If you could find one of these, have the plenum divider milled out and port matched, and add a pair of 650 AVS2s, it may be your best option.

There was an older style you may could find used that was made for spread bore carburetor LD, in case you wanted to run a pair of ThermoQuads on it…

Slap an edelbrock ch-28 dual four intake and a couple of 750 carbs on it.Fits under the hood and has style points as well.

Low deck motor. That’s why I gave a nod towards the Offy. But no doubt that CH28 with some port matching and the plenum septum milled out of it is a real animal. If one of those could be cut and welded to fit a B engine, it would no doubt put the car into the 11s.
 
TM6 works excellent on a 512 on a street car. My roadrunner is 4000# with me. I went 10.90’s in street trim with a 4150/1050AN and one of those intakes.

Thanks for posting, this is the real world info I was looking for. Maybe I’ll sell the Yorker I just bought and start looking for a TM6. How tall are they?

Not tall at all, it would fit under a flat hood no issues. They’re better intakes than the Torquer. I’ve even ran a dominator on mine using a 2” adaptor and it flat screamed. I don’t have any data with it though, I could only get away with running the car on “no et” days because it has zero safety equipment. Absolutely great street manors on the big motor. Even with the dominator you could daily it if you wanted. I’ve ran a few other intakes on the car including an Indy single that’s M/W ported. The Indy was a little stronger midrange and top end but it’s a big intake. It still wouldn’t be what I consider a blow out difference. For a old school intake the TM6 holds its own.
