yea but as long as a rod didnt let go the block is normally worth saving. as long as the bottom end stayed together.
whats beat is your in alabama. i have 3 blocks, 2 cranks, some other misc stuff you could do a pretty nice motor with. all GM stuff too.
i have a 010 4 bolt studded main block, a stock 010 4 botl main standard bore block, 2 factory GM forged steel cranks, ones from a 327 the other is from a 350.
see if you were to build a bottom end, you could have a forged crank which will hold 650hp without a problem, could get eagle i beam rods which will hold 550 easy , hyper pistons which work great in a daily motor. run a set of cast piston rings, m55hv oil pump, stock style pan, double roller chain, nice little dress up kit and a set or smaller iron eagle heads. would be a good motor probably around 350 hp depending on cam. just run a regular flat tappet cam and be done.
crate motors scare me. companies try to rush things to much and stuff gets overlooked.
