| Compression ratio on stock '67 410 |
| By BOYD - 12/19/2001 1:30:08 PM; IP 67.24.140.128 |
| I had my block bored 30 over and had my heads resurfaced but not milled. I'm trying to get to about 10 to 10 1/2 to 1. I'm using stock cast pistons. I took my heads and pistons to a different machine shop to get the heads done to achieve this but they had two different books, one says 8:2 to 1 and the other says 10:5 to 1 for stock piston and heads. Does anyone know the right C/R? |
