Stumbled across this while gathering safety equipment for my half ton, bolt in parachute mount for the Silverado's. Fits half tons but the bumper bracket to frame holes is the same I believe on the 3/4 tons...
Ideally, with a hot bottle (1200psi) a .67 jet is right at 80-100hp. with your injectors you have plenty of fuel on tap so I'd start small .040 range and work your way up. I didn't start giggling until around .067 jet, so I ran the .105 :rofl:
