Woodstock motor junk

Woodstock motor is JUNK. After disassemble and rummaging trough piles of Pontiac parts, putting it all together, installing it, we fired it up only to discover a cracked lifter bore. (lifter and push rod exited out sideways. Good thing for crags list found 400 motor & 350 trans & headers for $395. I talked to him about lemons and got it for $200 and he kept the headers and trans. It hasn't run in 20+ years and he says its out of a GTO . Casting numbers says 69 ram air III heads and 400 big car ( Bonneville) block. I put in a oil pump and checked the bearing clearances. I will start it up today if time allows.
