I'm sure you'll enjoy the power. What's the compression? Which BTR cam? Why the small heads?

BTR cam is the LS7 STG3 238/250 - 652/632 - 113.
Had the heads and Brian Tooley said put them on they won't hurt the overall result. Appears he was right as the motor put out more rwhp than a similar motor with larger heads.
I suppose I should start saving for a new differential now.

Was the similar motor tested on the same chassis dyno? Do you have any track results yet?
