Love to have those heads - w /the 28s and the 3.90 gear your only turning about 5700 rpms thru the traps and those heads are just starting breath there. What RPM are you shifting at?

6800

6800 now your talking and things make a little more sence - my 355 is is very close to your compression & cam w/ RHS 220 heads. It's shifting @ 6800 and goes through the traps @ 6800 pulling 530 HP. If it's in the cards you need to up that gear, am I correct with you traping @ 5700 ??
