Best cam specs for low end torque What would be the optimal cam specs for low end torque? I've got a 6.0L in my 71' Suburban 4x4. Pretty much never see's more than about 4k rpm so top end power is useless to me. I've currently got a 210/218 551"/551" 114 LSA in it now. Do I have much room for improvement?

For Specs at .050:
Set IVC up around 35-38 ABDC. Place EVO at 40, or more if on stock manifolds. Open Overlap to -8 if stock manis or +8 or more if on headers. The quicker ramp and more lift of aggressive lobes will only increase output.
Depending on if you have headers will justify whether to increase overlap. You have room right now, if that is the case. As for the other specs, the existing cam is close to a touch conservative, assuming on a +4 advance, which is what Crane does all the time.
Wind'em up and watch them go!!!
