Thread: 350 chev vs. 400 chev

Check with your cam manufacturer to see if the one you already have will work in a 400. I used early 327 heads and just drilled the steam holes myself. You may not want to increase the compression that much. Quite a few late seventies chevy heads were prone to cracking not just on 400's. Hank
