Thumpr Cam?
When are you going to FayettNAM track again? Sounds awsome and runs like it sounds. I almost bought a thumpr cam for my G8 but worried about tuning it with the HP Tuner....maybe I need to reconsider. Ended up with a custom Lunati cam that I am running/tuning at Fayetteville Sunday T-n-T. What rockers are you running with the cam?
I'm running the stock ratio but they are the Scorpion non adjustables. They were cheap and pretty. Checked them last week and so far they are good.
The Thumper cam is not that hard to make idle. Raise idle speed to 750-800rpms, set base timing to 30-35*, add some air with RAF, raise Park air a little and make sure commanded and actual AFR agree.
Actually I'm going tomorrow but not with the truck. The lockup in the converter quit after 3 years of puishment so I waiting for it to show up next week.

Damn! That truck Flyes!, Great Job, Gives me Motivation to finish mine!, Thumper cams work well for they're intended application just like any Camshaft, FWIW Wide LSA Cams allow More Static Comp Ratio than Narrow, the Later Closing Intake valve is what determines that
