If RPMs is what you want:
Big heads
Alum. rods
Lots of spring pressure
and a big stick
is what your looking for.
GOOD LUCK :?
Thatsw what I have exactly, Except 7" Oliver rods. Heads flow 520ish, 288*,298* @ .050, .883Int, .833Exh at the valve, The new Brodix Intake design. I upgraded a couple of things along the way also. Dry sump, .904" lifters, Curtis did some more touch up on the heads and intake. So if this thing likes 8500+ thats what it'll turn.
