Hey guys, any of you using the SHP Pro block? What are the pro's and con's? Anybody take one up to 1,000HP yet? How is stroke clearancing? I would like to go to 3.875" myself, if I get the block. With a BBC cam bore how is rod to cam clearance? I plan on using one of these to build a forced induction 421sbc. I scrapped my stock block build in favor of picking up one of these blocks :yes:. So I will be offering up both my stock 400 (511) blocks once I order the SHP Pro block. Any help and info would be greatly appreciated. Thanks again guys!
