LS1 conversion .. which trans to use?
LS1 conversion .. which trans to use? 79 z28 getting an LS1 383. Options are the th350 it comes with, a 1970 Camaro Saginaw 4 speed, t56 or a 700r4.
The th350 and 700r4 I already have, the Saginaw is $100, the t56 will be a hunt for a deal.
What would be the better option and why? All would need to be rebuilt anyway to handle the 383.
I would need the pedal assmeblies as well for any standard trans that gets stuck in.

As always, just my $.02
Transmission selection depends on what the plans are for the car. I would rule out the Saginaw first. They are the weakest 4 speed gm ever used. If the car will be mostly street driven, with occasional track time, go with something with overdrive.

Going to cost some $$$ to build a 700r4/4l60e to live behind a LS1 383. Not that I'm against it. Personally, I'd be looking for a 4l80e....but some people don't like the gearing difference when compared to a 4l60e.

T56 all day long..yes its worth the money to get one and have it built ..you would have 6th gear for that really nice overdrive for long hauls..get better MPG..and can flog it if you want to..that and i hate having a computer tell me when to shift..

If MPGs matter to you at all, go with the 700. There are people that know how to build them right...one example...http://www.bowtieoverdrives.com/cata...SUBCAT&CATID=B
