GMPP Cams (Hotcam, LS6, ASA, Cup), what lobe?
#2
OK, I think I found one for the Hotcam:
Intake: 279-219=60
Exhaust: 287-228=59
Not as slow as I would have thought (quite a few Lunati lobes check in at this range).

well, getting married soon so modding has taken a back seat! Alot of people trash talk the asa. For this reason i would like to see what its capable of. The more i read on here the more i want to put a huge cam in. But i think the most important thing is having a setup that works together. Hence gmpp cnc ls6 heads + asa. I would rather have the asa that may make 15 rwhp less than the huge cam but never have to worry about valvespring maintenance or having to take my stock bottom end to 7k rpm to make power. I think this combo would work well together and your engine will live for a long time.
