Blown alcohol small block?

Cope said

550? Wow thats not much. I was hoping i could get 650 or so out of it. For some reason i thought their limit was much closer to 7 or 800.

Thats kinda a bummer...

Im definitely going to be north of 550HP, I didn't spend all this money to make what a NA Chevy dose. I told my engine builder if it comes in under 650 i will not be happy and that was my number on pump gas. I guess there's really no reason to spend the money on injection if im that hamstrung by the block.

Thanks for the advice!

At 500 HP N/A you are asking the block to do things it can't. You'll need studs, you should have better main caps, you have to run way more oil clearance than you should because the main line goes oval. The bores move all over and ring seal goes to hell right quick.

The decks are so thin it's almost impossible to seal the head gaskets. The main webs are too thin and the tend to fracture at the oil feed hole up the the cam bearings. That's telling you the block is spreading.

Many guys get by with a stock block. But they are giving up power because of all the issues noted above.
