porting intake questions

I would not bother with porting the intake myself. Your not in a race effort arena. You'll also not feel 10HP or TQ. That particular intake is very well designed by Holley. You'll note when you look into the plenum the runners have dam's built into them.

At one time, Holley was making some of the absolutely best intakes. They did a lot of R&D before they released the intake as to be sure it was better than Edelbrocks offerings.
