compression
my motor is a 67 327, 4bolt mains 9.75:1 compression camel, hump heads(2.02x1.64) the cam is a Speed-pro 291`-.447� lift cam.. it makes 350hp and 370ft. lbs. any suggestions on the most efficient way to boost compression on this without actually changin pistons. ALSO if anyone has any thoughts on what cam i should stuff in the motor.
