Thread: I have mis-matched parts where to start?

Without knowing gear ratios, how much the truck is weighing. Still stock or lightened up, etc. What's your compression? So, still missing some vital info, I'm gonna tell you to run the comp cam. That particular grind has a nice pulling rpm starting lower in the band. Especially if you advance it 4 degrees.

Your lack of low end probably comes from A) Having a cam that doesn't start until 2500 RPM, and B) You're most likely running a stock converter, which will stall no where near 2500. You'd be better off to run that Comp cam. I'd bet that it will make a difference.
