hey guys, i need a new block for my y8 and i found a y5 block for free and its in good shape. i want to put in new rings, seals, and bearings and then boost it. i would put my y8 head with y8 head gasket on it however, what kind of compression would this give me. any issues with this setup? how would the block hold up to 6-8 lbs of boost?
