I've got an 81 z28....i know what ur thinking not the same body style...but you guys prob know more about somethin that my 2nd gen brothers don't...and that is the th700r4...i've heard some of you 4th gen guys downgrade it but you just don't know what its like to not have od...my question is about the gear splits... my camaro has a 3.23posi in it now and i just put the tranny in...i can drive it for awhile cuz the body needs work....but i was wonderin if any of you have the th700 with a 3.23 posi and i would like yalls input...well heck i'd like input from all yall if you will.. i was just wondering if i should leave it the same or go 3.42,3.55,3.73....i know the th700 has a lower first but will the 3.23's make it run like a dog in 2nd and 3rd or are 2nd and third not split too bad and will it accelerate nice. i've got 375 early hp and nice torque ...only think i need to remember is the large weight difference...thanks camaro brothers i always liked the fourth gen...lata
