I have been talking with him and he has not produced one in a while he needs more interest in this item.

There's probably a good reason there is little interest in them.

I thought the "1500 hp stock block" statement would bring more conversation....

I know next to nothing about big blocks but I might start by looking in the 9 second and faster thread. Might find some real high hp guys over there with some info on those.

Wish I could be more help!

The four bolt means little when the webbing above the crank and the bottom of the bores are weak.

I don't care what you do to a stock block, it's not going to take over 1,000hp for very long. If you want to make over 800hp, start shopping for an aftermarket block.
