Auto trans choice for 67 Chevy II Hey guys/gals,
I'm in the process of acquiring a LSX based motor/trans for my 67 chevy II and I think I'm set on going the auto route at the moment. My question is should I go with the 4L60 or 4L80E transmission? Given the light weight of the car, I was thinking I should be ok with a 4L60. However, if I can get away with running a close to stock 4L80 I would be fine with that as well. I'll likely be running a stock bottom end with LS6 heads and a "street" sized cam, heh. Nitrous is a strong possibility as well. I'm trying to stay somewhat budget minded as all of these mods ad up!
Here are some details on the car:
Currently running a TH350 w/ 3500 stall
9" rear narrowed - may swap for a 12 bolt
Checkered racing front clip (QA1s, tubular a-arms, rack and pinion) - significant weight savings here
Fiberglass fenders and hood
Car at the moment is full tubbed - the trans tunnel has been modified so I've got LOTS of room to work with
Thanks for your help/recommendations!

You'd probably be OK with the 4L60E, since plenty of fourth-gen F-bodies (which usually weigh quite a bit more than your shoebox) are running them. Honestly though, if it were me, I'd be more comfortable with the 4L80E, especially given the possibility of nitrous use.
Just my 2c...
