1977 Pontiac 400 Engine Block with Crank. Block is currently .0 30 over might clean up at 40 I have rods and 40 over Pistons to go with it. It will definitely clean up at 60 Crank is 10 on the rods and 20 on the mains should clean up with a polish.
Number two cylinder has a sleeve in it. I looked through the front water jacket, and the side where the freeze plug goes. I do not see any damage. It must’ve been due to pitting at one time. also have other engines 455, 400s stroked to 455.
