RE: 427 overbore
By David Thayer - 01/17/2002 9:11:47 AM; IP 158.52.254.238
The 427 was really strictly a race motor, the thin wall casting did not allow much margin for overbore period. That is why you will see a lot of guys use custom pistons and try to clean them up a 10 over, using the 20 over is good as you can use the BB Chevy pistons. 30 over is proably the max and may not always be doable.
This thread, so far...
