Re: Big Block Chevy Main Bearing Caps
Those are the later main caps but work on all two piece rear main seal blocks. I'm not sure when they started that casting number. I'm guessing in the late 70's early 80's but that's just a guess.
964 is the more desirable caps as they are correct for the earlier blocks.
