Course, a 40hp gain on 500 doesn't look quite as good as a baseline of 300

Coltsteele your truck is going to be insane when you finally get it back, it will be very hard to wipe that grin off your face. I can't wait to see what it will run down the track.

BTW the A/F at 12.5:1 is very rich for N/A. Target is 14.7:1. Not unusual for vehicles to be rich on the dyno, the stock computer likes to feed additional fuel to keep the cats cooler and from melting. A few more miles of driving should get the A/F leaner and more power.
Head work ( hone, port ) is freeing up an additional 40hp on other trucks with your mods. It comes at a price tho! Sweet numbers any way you look at it

12.5 is only slightly rich for an NA car/truck

ktm, The 6.1 cam has a little more than what we had thought in the past. With all the contraversy going on with the 6.1, AB and AC cam's, we took the liberty to measure them both. The AB and AC have the same numbers. However, the intake has a .547" lift and the exhaust has a .529". I don't have the duration numbers in front of me, but from memory, the LSA is correct. In otherwords, this little stock cam is a whole lot bigger in the real world.
