Now I have done lots of reading but I really can’t understand or wrap my head around motor performance, I have a 1997 gmc truck with the 5.7 vortec? So what I have on my list is set of long tubes, and am gonna run either duals or 3 inch out straight, next I’m gonna upgrade spark system , now the hard part for me is cams I want an upgrade cam but don’t want to upgrade the springs and stuff like that and would like to upgrade the intake manifold if it’s worth it , what do you guys recommend? And am I on the right path?
