RHS head 416 at the track...part 'tree

Dusterdoug, now what are you running for jetting. What did you start with and whats does it(did) run best with.

Every time iv'e been to the track the car smokes out the exhaust. I still have not been able to get a proper tune out of this car beacuse of lousy track prep and suspension tire adjustments thrown in. Anyway it seems to run best with 75 primaries with a PV and 81 in the rear without thru 3" flowmasters at the diff. It seems these heads don't respond well to overjetting?.
