The motor is basically stock with the exception of a slightly larger cam (don't exactly know what size) and headers. The car is auto with a 4:10 rear. I am thinking of upgrading to a performer rpm air gap intake and a new carb (has a stock intake and Holley 750 vac on it now).My first question is with the minor engine mods is the intake upgrade worth the cost? My second question is what carb should I run with this combo? (I prefer Holley) Thanks for any input. 1970 Challenger 1973 Satellite 400 1974 Barracuda 1988 D-150 (LE-150) SWB 2010 Crew cab Hemi Ram 2019 Crew cab Hemi Ram
