I like how flat the HP is from 6,000 to 7,000 and TQ is still up there at 350 at 7,000.
What compression ratio are you running?
What spring, lifters and size valve are you using?
Looks like you have great valve control at 7,000.
What spring, lifters and size valve are you using?
Crane dual springs (no shims, .075” preload)
Stock lifters
Steel valve seats, 2.05 intake, 1.60 exhaust
BTW I saw a set of those Rapid heads and they look pretty sweet. Mikey's heads always perform.
