I have a 2000 Silverado 1500 4x4. It has a 6" RCD suspension lift with a 3" body lift. I had the 5-speed manual transmission regeared. It also has 4.56 gears with auburn posi. I have 315/75/16 Baja Claws. I am also running true duels with high flow cats and cherry bomb extreme mufflers(they are loud but sounds great). The hypertech programer does help a lot with power and it doesn't effect gas mileage.
I installed a 6.0 LQ4 and now I bought a powerdyne bd-11a with intercooler. It didnt come with the right mounting bracket. Does anyone know where to buy just a mounting bracket for the supercharger? Also I was told that the engine could hold up to the 6lb pulley but didnt say anything about the 9lb I have. Anyone know what the engine can hold up to and should I change the cam out?
