Re: Best highway RPMs

i dont have my LS3 going yet...but all the other swaps ive done i try to shoot for 2000rpm at 65...
it is more than my 13 z71 turns...but the 2k seems like its my sweet spot for power,mileage and noise
but my LS3/tr6060 was in front of 3.31s but when i get it in the truck, ill shoot for 2k at 65 on it as well
