Flowmaster Super 40 vs Super 44?
This is my Silverado. I am debating installing the Super 40's or the Super 44's. What do you think? The engine is a 86-95 350ci block, four bolt mains, roller cam.

Comp XR276HR-10 cam, 1.52 rockers. Air-Gap dual plane, 1" four hole tapered spacer, Mighty Demon 750cfm annular Boosters. MSD ignition, Summit dist dialed in for 36 degrees @ 3000rpm. 18 degrees initial. +12 vacuum advance on manifold vacuum.
