So tired of my old sbc in my 72 camaro. So going to really get on looking for a ls. Si from what I understand the 02-06 6.0 are best to use with a 6 speed and as for 5.3 same? Thanks
02 they did away with EGR 03 they started drive by wire 05 had the better rods/pistons not sure when gen IV started but expect a bit better gas mileage with them
