My slightly informed judgement on the stall was based on your DD peak tq spec at 4000. I've heard that you want your stall to go where your pk tq is...

I would have to defer to the cam grinder as they should know best.

Where do you shift? 7000?

Seems from your specs this is intended as strictly race vehicle? What compression you running (I'm guessing pretty high 11-12+)? Pardon my ignorance but are the 390 heads rect or big oval?

I'll stick with my mid-11's prediction maybe into the 10's with a good tune. Should be a fun trip!

You might get more top end out of it with a bigger primary on the exhaust(?)
