Sorry to ressurect an old thread... got a 3.42 gu6 in my envoy xl and found a tb ext with a gt5. I'm thinking of trying to get it for 2-300... I drive mostly stop n go and hills and like I stole it. Even with a 5.3 and stock tires it doesn't get out of it's own way fast enough for my taste. My 3/2 lift and wheel adapters are sitting in the garage and I'm probably putting 31.5s or bigger/heavier on in the next 2 weeks. I already drift it wet but it's gonna need much more pull to merge easier and drift dry with the bigger heavier tires/rims. Hoping to have tq management lowered and 4.10 in by end of sept. Down the road a bit low lift truck cam/springs and LTs catless Y and nice exhaust. Mainly looking for more fun driving. Will the 4.10 g80 be ok for some fun.? I won't be doing doughnuts or launches testing for wheel hop regularly. There is a rolled tbss near me I'm hoping to get some parts from eventually but for now hoping to go budget for a bit til at least my current parts are installed got a big alt and stereo waiting to go in
