Reused standard rockers when i went to EZs. Also no header issues. -1s have a raised exhaust port. Plus EZ heads are pretty cheap

Ray, were you able to open up that Weiand TR to MW size without building up the outside?

No problems with that plan.

It's an 800hp motor with a 700hp induction on it....... should work fine.

Fast, it needs to be welded. I bought it from a member here welded up

Two good reasons, that's the kind of info I am after- thanks.

Rick:

You should find this righteous piece of machinery up your alley:

'70 Cuda, Black Series


The car belongs to John, jbc426 on here.

Thanks Grizz, John's got a great car there and pretty much what I'm going to do with mine (the previous owner had already started down that path in 82) The guy interviewing/hosting though....that's another story...

World block 4,32 bore
Ohio crank 3,76 stroke
Molnar rods
CP 10,5 pistons.
BIG I mean BIG roller cam
T&D 1.65-1.7 rocker arms
Jesel belt
Max ported Mopar stage V heads with 79,5cc chambers with stock size intake and exhaust runners. 2.08-1.74 valves
Custom sheet metal intake
Revers cooling
"Stock" sixpack carbs

738hp 652lbs tourqe

Thank You!

I've heard that above 650-700 HP, RB blocks go boom! For the power level you're trying to attain, you may need an aftermarket block, or at least some help to stabilize the bottom end (Girdle). Good luck with your build.

They go boom only if you use them........crank likes going on vacation through the pan.

I don't know of any crank girdle that reinforced the main webbing
It is the main webbing between the bottom of the cylinder walls and the main bearing bores that fails on the RB,440, blocks, not the oil pan rails or main webbing ribs from the oil pan rails
The girdles can't fix that, new better race block do that well

Would you be willing to put an Indy block in this project? Many advantages, if you will. Weight off the front is a huge advantage for starters. On top of that, 35 less HP should mile an hour as fast.

Yeah, It certainly seems like I would be pushing the blocks longevity and that a mega block would be strongly advised. I would like to ultimately go that route, it will just mean that I'll have to wait longer to do this buildup- I'd rather only have do it once though.

The girdle will keep the main caps from moving around which I would think would put less stress on the webbing ribs. Tying everything together, pan rail, main caps plus a half fill on the block should stiffen things up. But, your still working with a 50 year old block.

I was thinking a max-wedge port, not sure what a stage 2 port is, is that just gasket matched and cleaned up?

I was wondering about that as well as the website does not say anything about a stage 2 port.

IMHO a megablock in cast iron will put a lot of weight on the front, making it very hard to hook. The traction difference for unpreped surfaces is huge!! Go aluminum, or at worst a low deck with a lowdeck sixpack, my opinion on this. If you are also going to have a less than optimal suspension, the situation snoballs some more.

Why a lowdeck Greg? What is the advantage?

If you go to the Hughes website on the tab "Instructions & Tech Articles", then "Intake Manifold Articles" and then link #4 you will see a bunch of manifolds they flow tested and give the flow numbers for stock, Stage I and Stage II porting.
