It will work but require a tune to calibrate the MAF tables. Plus I would get am 85mm since that is what it came with. Get a truck 85mm off e-bay for about $50. I am not positive the truck MAF is calibrated the same as an LS2 MAF so may require a tune. If you run the LQ4/9 part #'s and they are the same as the LS2 MAF you are golden.
