If my memory serves me right :confused: stuffing a small journal 327 crank and rods in a 283 block, is what chevy did to make the 302 cu in motor. eek I found the head article in august 1978 street rodder mag. It is a very detailed explanation of the heads out there. Go to you're profile and send me a private message and we can get the info to you.
