Stroker info ??

[dwc43]

Wanting to build a 426 wedge. I have a 383,400, and 440 blocks on hand. Also have a specific RB intake I need to use as well. HAte to use spacers to make it work on a b block, but I may have to. Would like to get it as close to 426 as possible. Any suggestions, before I look into this further ?

All the info can be had @ Indy or Hughes etc....
Port match the spacers if need be and it'll be fine.

alright, im still confused dwc, the 426W is a RB right?, so, you would have to de-stroke or sleeve your 440 to get 426.
stroke a 383/400 to get 426, but, the RB manifold is wider than the B, so how would spacers help you?
or am i just too stuffed up and stoned on cold medicin today?

The RB manifold is too wide for a B, not too narrow. I think MP offers a cylinder head that uses RB manifolds on a B but they are pricey. The 383 with a RB crank is 426 CID (4.25 X 3.75) but special pistons are required for this combo.

dodgetkboy78, destroking or sleaving a 440 is going backwards. Sleaving is not recomended at all to achive a certain cid.

jelsr nailed it. I got it backwards. He was thinking of MoPars Stage VI heads. The use of these heads are not striaght foward. On a B block, you use a RB intake.
If they were not so expensive, I'd use a set on my 400 and use a RB single plane intake.

That's what I was thinking of when I mentioned the intake. Stage V's and VI's. Do you have any info on the pistons? Thanks.

[rumblefish360]

Stage V's are stock heads and the Stage VI's are aluminum castings. The Vi's are not a replacment head.
Pistons can be had from most any manufacture for this. Most any comp. ratio can be had as well. Here speed-o-motive has been doing it for decades;

KB has several varietys in cast hypers and fordged;

A write up on a 451 can carry over to a 426 stroker wedge project.

Heres a place that has a better handle on big block strokers.

Sorry, nothing exactly specific on a 426 cid build. But I think it's Indy and Muscle motors have kits and speced parts for it.
I was doing some looking around on a stroker. I have a 400 looking to grow up. I was thinking 500 cubes, but a 451 seems a tad cheaper. Non the less, I shelved the project. It can wait.

[dwc43]

Yeah, this will be the 1st stroker for me, but it has a specific purpose and I'm just starting to gather up some info. Thanks.

how big of a pain is a 4" stroke in a 318?
would make some torque! and is around 400 cubes right? (400M ferd is 4"x4")

[rumblefish360]

I think it's Hennsley (SP) thats doing it. There also taking the 318 out to a 4 inch bore.

Already sent a PM. 3600 sec delay between PM's so you'll have to wait or give me an e mail addy. Are you a Music City Mopar Club member??

Thanks, I sent one of them an e mail and we will see what kind of pistons they can come up with for this idea.
