Any suggestions on a what camshaft I can purchase to uprade my performance?
I have an 01 silverado with a 4.8..I installed a cat back flowmaster dual exhaust..put on some shorty headers, cold air heat sheild intake, and max energy performance chip already..Im a newbie to all these upgrades so Im still learning..Ive been thinking of my next move..Ive been reading about the LS7 camshaft..is this a good choice and if I swapped out OE for this camshaft, should a replace the springs as well in order to see an actual difference in the performance..thanks for any input
