So thinking about having some headers made for my 392 hemi in my 3/4 ton, I have a BGE with .025 off the heads .020 off the block deck and a 5.7 truck cam, I am borderline thrilled with the TQ curve but would be thrilled if I could get just a little more at 2500ish RPM... what would an ideal long tube header look like that had maximum tuning lengths and diameters to boost low RPM TQ from say 2000-3000 RPM? Long and skinney I would imagine but what would the computers like pipe max suggest?
