The truck is back on the road and running EXCELLENT!!! However, I did change the compound turbo setup from HX35/12cm over HT3B/26cm to something I've been wanting to try forever He351cw/9cm over S480w/race cover/1.32ar as well as went to a .010" thicker head gasket so compression is down right at 16:1.
The truck runs much cleaner in the mid-range and top end, idle haze is less as well, probably due to the 26* timing hitting the bowl now instead of the lip....
I haven't beat on it yet, want to get a few more heat cycles and then do a re-torque on the ARP 2000's. So far at 70 psi, it pulls well, I'd say 575 HP to the tire, clean out the tailpipe, S480 loping along at 30 psi.
Did I mention spool-up is excellent!!!
