Hey everyone,



I recently bought a 1992 Camaro Z28 with a 305 (TPI) V8 and an 700R4 automatic transmission. This is my first build, so I’m still learning as I go.



My plan is to do an LS swap and pair it with a 6L80 transmission. I’ve been researching different options and wanted to ask if anyone here has used a 4x4 version of the 6L80 and modified it to fit in a third gen F-body.



If so, is it worth it and what all was involved? Tail housing swap, output shaft changes, driveshaft issues, crossmember mods, tuning, or anything else I should know before going that route?



Any advice, build threads, or lessons learned would be greatly appreciated. Thanks!

 

Here is "any advice": Leave the car alone. Make that TPI 305 run as good as you can, keep the 700R4, and just drive the car. Enjoy it for what it is: a cool piece of 1980s history.

 

Automatic 4x4 to RWD conversions require a complete teardown to replace the output shaft and then use a RWD tail housing
The output shaft is one of the first pieces installed into a trans case

Same for 700R4, 4L60, 4L60E, 4L80E etc

If you're rebuilding the trans when going in, sure it's fine for a core as long as the trans shop can source the missing pcs
DIY, I don't recommend it

Also, the 6spd case is enormous compared to the earlier 4 spd autos. Controller options are also limited, so it's not a great option for 3rd gen LS swaps

 

Test drive a 2007 truck and a mostly identical 2009. You'll be able to decide if the 6 is what you want. My vote involved buying an E38 5.3 6L80 truck years back because it wasn't a 4L60.

As with all swaps, the closer it is to a complete production power train, the more likely it will drive nicely like one.
