Only thing bad about the 80e is the gearing. I think i'm going to stick with a 60e just because of that....I guess i'll see how long my stage 3 ls1speed tranny lasts.

the 80E supposly has gearing similar to a TH400. like the 60E its comparable to the TH350 as for gear ratios. from what i read ppl with the 80s are stepping up in gear to help make up the difference. also the 80E will rob more power then the 60E
build that 65E you have up on the hill to handle that beast

an 80e doesnt use a band like a 60e and the clutches are alot stronger and built differentle.
if you put the 80e in and then you step up on the stall probably 400-600rpms higher you will probably not notice a difference. I have a buddy with a 408 in a trans am and he is on his 6-7 60e becuase he doesnt want to loose the power. He is now looking at buying a conversion kit from speed engineering.
