L99/6l80 swap

Yeah that’s what I was afraid of, and why I was trying to stay away from any trans tuning. Well I’m going to be changing the rear differential anyway to a limited slip, so I could always go down to the donor car’s rear gear. With the tire diameter being the same, it should behave exactly like a Camaro. (At least from a tuning standpoint.)

Not to mention, the 3.27:1 rear gear would be a welcome change. With the 6L80 having a 4ish:1 first gear, the 3:73’s would be a handful in a pickup with no weight in the rear
