ProComp/Speedmaster aluminum heads

I'm not even sure what it wants to shift at.. it spins to the rev limiter (7200) so quick it's hard for me to feel a layover point. I obviously dont want to spin the sucker into Oblivion either.

I doubt 7200 is the sweet spot............ I also don’t think it’s 6000.
My guess is, best ET will be somewhere in the 63-6500 range.

You just have to experiment and see what works best.
