Default What trans for a supercharged 68 lemans?

Working on some cancer repair before the build really takes off currently. Figured as I do thatvid collect parts and see what deals I can get. The question I ask is do I go with a 4l60e or a 4l80e. Thanks to hooker I have either option with some help from a bfh. The plan is a supercharged 5.3 with a custom ground cam. Torq storm supercharger at 8 to 10 psi. Mostly street driven. Just looking for opinions on which trans you would run. Just don't wanna have to do it twice or be way overkill for what I'm running.

transgo shift kit and a converter should be good.

Look at how many miles on it. If over 200k, rebuild it plus the stuff above.

Transgo HD2 does the job on a stock trans.

CK Performance sells great kits for cheap too if you feel like opening the trans up a little.

Thanks for the replies. I just wanted to make sure that a basically stock 80 was going to get the job done b4 I decided on a trans.

IIRC the sloppy mechanics colorado has a 150-180k mile 80e in it with just a converter and shiftkit and it made over 1000 tire. he routinely beats that thing on lower boost making around 4-500 though.

In my experience i would suggest go with an 80e and be done with it. Circle d makes an affordable converter that has worked well in ls combos with our supercharger.
