oh ok,i just tought they were diferent,ok so if the 1st gear ratio is diferent will it screw me in my ets,or help me,the tranny he did say its new but i dont know how he got it built,only way to find out is for me to put it in the car,cause when ever i try to run that car n step on it it chocked out,well so the rest of the gears are the same as a 302 t-5 right??i'l le tyou guys know when i part it out,i probably just give most the stuff away,caus ei just want the tranny and a few parts
