Pick the one u want, then go two sizes smaller! Hah. Seriously. I love this forum and all the extremely intelligent people here. But for a heavy truck with a small motor go a little small on the shaft. Keep in mind who your asking when posting here. Most of us want max power and don't mind sacrifices in drivability. So your going to get suggestions for 240 ish @050 cams with 600 plus lift. But is that best for your daily driver? No. Will it dyno higher? Yes. Will you wish you hadn't? Yes. With that said. No stall. 3.42 or 73,s on a 4.8 look for something 218/224. In the 550 range with 114 or 115. You'll get torque and drivability with very minimal compromises.
