4.10's
turns out i have 4.10s.
also found out that there used to be a sway bar, different lid, and it has a fuel cutoff valve on the end of the driverside fuel rail where im guessing it had nitrous from the first owner cause the guy i bought it from didnt know a thing about cars. also i can tell it had completely different exhaust on it so now im scared **** is gonna fall apart. it had a stock tune on it and it runs great still but with the 4.10s and signs of nitrous, im worried the first owner beat the crap out of the car.
anyways im also curious as to what mpgs i should be getting with the car tuned for 4.10s in the city? i got 150 miles in a 1/4 tank of gas doing 70 coming from back home on the highway but since then ive put about 90 miles and burned a little under a half a tank. granted ive gotten on it a little bit when an 05+ gt wanted to race (silly horsey)
my main concerns are the rear end, tranny, and getting the rusted manis off lol. im afraid to unbolt everything for the lts cause they are pretty gross.
