Will, is there an updated build list for this truck? wanting to know how much boost you are running and if its o-ringed or fire ringed? what studs?
Thanks
The only real changes since a year ago has been the transbrake VB and the HT80/364.5sxe compound setup. I'm running 28* timing on the same Farrell 215 based pump. To keep the head glued down I've gone back to ARP 2000 "cheaper" studs torqued to 150 ft lbs on a regular 041" stainless oring wire in the block on a stock gasket. We've done a little bit of wastegate fine-tuning on the dyno with the PDD turbo tuner and picked up 40 HP in the mid-range by correcting a problem where the 40psi internal wastegate was opening too early and causing a dip/plateau in the HP curve between 2600 RPM and 3000 RPM.
