Good thread guys! Very spirited!

Remember, headers ADD torque at ALL rpm's. A difference you can feel.

I'm also of the compression-over-flow crowd. BUT, I never install 516's with the 1.60 exh. valve. Always add the 1.74 valve and a quick bowl/intake/exhaust template porting and YOU WILL feel a difference in the whole rpm band. 13.08 at 106 mph with a 3600 car with my favorite "boat anchors.




Here! Here! Lets start a boat anchor club and compare it to the book worm club!

I absolutely agree on the 1.74 upgrade. I did that with mine and kept the intake size. sometimes bigger is not always better...especially for the B blocks.
