Another 60 vs 80 question.
Long story, short. I decided against all of my smaller upgrades, and put all the money in savings. I've been reading and reading about blown motors followed by blown transmissions. Since those will be my biggest purchases I decided to get the tranny first, atleast that way I will either get the core charge back or I can sell my tranny to recoup some of the cost since it wont be broken in half. Now for the hard decision, Speed Engineering's 80 conversion or FLT Level 5 65? In all of my horsepower hopes and dreams I doubt I will see 600HP to the wheels. But I do plan on going with FI preferably radix. Is the 80 coversion worth the extra $600, weight and extra work to install? Has anyone broken a FLT level 5 65 yet? I only want to do this once. Any and all information is appreciated.
BTW I still plan on LT w/ ORY, EFIlive or HPT, Detroit Truetrac

The only real difference between a 2wd and 4wd 80E swap is changing the input gear on the transfer case and having to have a second driveshaft modified to fit. I did the 80E swap after going through six 60E's, but I think my builder wasn't the greatest. I have yet to hear of anyone breaking an FLT level 5 65E.
My decision was to get something that would outlast the truck, I never wanted to mess with the tranny again after breaking so many 60's. Overkill? Maybe, but peace of mind? Definitely.

Yeah the big problem with the 4L80E is the 2.48 1st gear vs the 3.05 1st gear in the 4L60E. The problem with the 60E is that the 1-2 shift is a killer, going from 3.05 1st to 1.75 2nd, where the 4L80E goes from a 2.48 1st to a 1.48 2nd.
Once you're moving though, its sweet. 1st gear will take me up past 60 mph, 2nd takes me to about 105. It's nice being able to catch a 1st gear downshift when cruising at 50mph.
