Looking for what to plan for next. I have a 1997 C1500 350 5.7 ecsb. I have a kn cold air intake, e-fans, long tube headers with straight pipe no cats and a x pipe, upgraded spider injection, 373 gears, 8mm Taylor spark plug wires, msd coil, ngk plugs, 100 shot nos wet kit, and a blackbear tune for this setup. It is my dd and I just wanted to make a little more power when I am not using the nos and I haven't did work on my truck in awhile. Feel the need to take.something apart.

 

Sounds like time for a cam and converter
