i thought all GMCs had the old tails? anyways, looks pretty f-n sweet. when are you going to put some 4.10s in that bish? helped my lil 4.8 drop .5 in the quarter. are those 22s? if so i'd go with some 4.30s
I plan on leaving the the 3.23's I am gonna turbo it and put on forged 20's so thats my plans.

God created turbo lag so nitrous trucks could have a chance.
