If a guy had a good standard 327 block and a good 283 crank laying around that would make a pretty sweet little screamer for honest money.
I was just at my neighbors place today, in his shop was a ‘69 Z28 with a 302 and M22 Just under 12k miles. Yes, many live a better life than I do!
Picked these up a short while ago 4.030 with a 283 pin height. I have an extra 283 crank and rods. Might just do it when I run across a SJ 327 block
