How would a comp 212/218 .522/.529 114lsa do for bottom end? And would springs be a necessity with it? That cam is the one that ive been comparing with the tr220 trying to decide which is the best for me. I really would like to have some good torque around 2000 rpm so i can pull all these hills in va without so many downshifts and stuff. But when i hit the go pedal i want it to come alive and leave my brothers 6.0!!!
