Bad idea man really a turbo 350 is just a 4l60e without overdrive if a th350 can handle what your doing a properly built 4l60e can to trust me if you saw the internals of each you would understand ,Stay with the 4l60e and get a good one and you will be happy .

a 4l60 is WEAK, even built, its gonna wear clutches on the 2-3 shift like crazy. the th350 isnt god by any means, but its gonna hold a shitton more abuse than any 4l60.

Yea LOOKING at the parts....it's the way it shifts that makes the difference. Meaning the 4L60E applies clutches on some shifts and applies/releases on the 2-3 , this is the weak spot. The th350 just applies clutches during shifts. A stock th350 is stronger than some performa..nce builds.
You need a converter spacer, crossmmber mods, etc to use a th350 in an LS1 F Body.
