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

I'm just sitting back looking at my original plan and saying why not go 440-1's or big easy with a modman that will fit them with EFI, on something like 570" 11.5-1, and a stick around .700 274-282. What are my plans biggest flaws? No problems with that plan. It's an 800hp motor with a 700hp induction on it....... should work fine.

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...

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.
Have a great day Iowan

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.

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.
it's ok to butt heads, just don't do it with a butthead

I just pulled out the invoice from Hughes and it says Stage II porting. From the outside there was definitely no welding or material added.
Paul I was thinking a max-wedge port, not sure what a stage 2 port is, is that just gasket matched and cleaned up?

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. 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.
