I have two 1999 suburban 2500's both with the 7.4 vortec, both 4:10 gears , one 4x2, the other 4x4.
I'd like to give the 4x2 just a little more power. I don't want to go crazy. Will a cam upgrade help? And exhaust?
I was going to go simple. A 285 /75/16. Maybe one size bigger a 305. I just need enough to clear those tires and look aggressive.
I also need to keep the lift cost under $1k
