Gen V Upgrades choosing a cam
I have a GMC Denali Truck 2017 with 6.2L 8L90E
2.9L Whipple 3.75 pulley 12~lbs boost
Stainless works headers
True Dual Exhaust
X Pipe
Venom 250 Mufflers
I have ordered a Circle D 258mm Pro Series 2800-3000 Stall
Rep said it would drive pretty much stock if I stayed out of the gas. Would not need any extra cooling and would maintain if not exceed the stock tow capabilities.
What I'm having trouble with is deciding on a Cam
I like some chop to my cammed Vehicles. But this is a truck and I don't want to lose all of my low end.
The factory cam is
200/207 .551/.524 116.5 (DOD/AFM)
I was looking at the BTR Stage 1 Blower cam
225/240 .64x/.62X 116+6
So I called BTR and had them put together a couple of cam specs for me.
The first cam spec
215/240 .630/.648 116.5 +3.5 (Noticeable Idle)
221/247 .638/.645 117 +5 (Rougher Idle)
I really dont know what the sweep difference in the torque and HP curves differ. My rep says he would go with the first cam but I think I would like the second one thats slightly more aggressive. I feel that BTR knows there stuff. But I crave a bit of the rump at idle.
Opinions?
