I have a question about 440 timing... I have a friend with a 440 and the book he has (stock mopar book) says 10°-12° at 2200 rpm although everyone else says run 34°-36° total timing, that mark is not even on his timing cover. All I know is I set it at 12° at 2200rpm, idle ends up being 0°. His car is a mild build 440 with a mopar purple cam equivelent and my magnum 318 with bolt-on will beat it easy... something isn't right... Can you guys help out??
