Reading "cam Choice" below has me wondering what do you use as a basis when you are picking available lobes off a chart for a custom cam?
My combo is as follows:
428 "C" block .025" over, decked and line bored (guess deck will be near 0)
SRP flat tops (-5cc relief)
4.25" Scat cast crank (to yield 461 cu in)
Scat H-beams
Blue Thunder small bore heads, having chambers profiled, minor port work as needed - targeting around 80cc but as req'd to achieve 8.2ish DCR
solid roller cam
Victor Dominator
Hooker race headers
68 Mustang with wide toploader and 3.91 at this time, will go deeper if req'd
The application is mostly radical street, 6500 rpm max. Because I have not finalized my combustion chamber size I am really not locked in to a certain duration to achieve my desired DCR but where do you start? thanks
