LTX --> LSX Conversion Sticky
TH350 and TH400 are 3 speed 4L80E is a 4 speed. A TH400 is stronger than a TH350. A 4L80E is essentially a heavier TH400 with overdrive and an electric valve body. As far as which would be best, that depends on what you want to do with the car. I personally wouldn't entertain a TH350 behind a TT 408.

Well its gonna be a street car and track car so basically as you quoted somewhere on this forum a race car with license plates lol but does the 4L80E have overdrive and does the TH400 have overdrive too? on a side note what would be the best option for the TT 408 Lq4 build?

well I'm gonna be driving on the street 75% of the time and the track about once every weekend, i wanna have the driveability of the O/D so i can not cruise at a high rpm and get crappy mpg even though i'd still have crappy mpg lol
I just scored a LY6 longblock for pretty cheap, and most-likely have a buyer to take my LT1 stuff. So that leaves me with some questions. Besides the LS1-style T-56, what other 6 speed options are there that will work? I want to go with a T-56 magnum, but I'm guessing that would not have a way to mount the torque arm. Do I just get a trans cross-member that relocates the torque arm off the trans?

Verdad Gallardo The T-56 magnum uses different electronics, although I'm not sure on what's different. Another 6 speed option is the Richmond 6 speed. As far as mounting, you can go to just about any of our suspension vendors and get either a trans crossmember with a torque arm mount on it, or you can do a short torque arm that mounts in place of the factory tunnel brace. I'd recommend Midwest Chassis.
I'm looking at putting an LY6 in my wife's 96 Ta... that being said , when it comes to the knock sensors should I run the ls1 style and drill and tap the block ? Or should or can I run the ls2 style knock sensor ?

I'm stuck on the fuel lines. Car getting swapped is a 93 formula. I have the corvette regulator, I'm just trying to figure out the best way to adapt the lines to the regulator. It looks like some people spliced them with rubber fuel line, but is there a better way or is this acceptable?

Same here! I got a complete LS set up TBody to Flywheel, harness PCM everything cheaper than switching over to the EFI 24X setup. I know I have to buy clutch pieces - front plate input shaft and hydraulics but that's right at a grand for it all!

Thanks again for all the help from everyone and I should be getting a build thread up soon - would be finished by now but like all things I do I went WAYYYYY overboard! I went all tubular A Arms and powder coated the upper A arm mount to match the UMI ones I purchased along with Koni Shocks and Strano springs. Spohn adjustable torque arm w/ds loop. New braking system from LS car - new EBC brake rotors and pads - stainless steel with teflon coated lines - Had the harness prepped by current performance with Nylabraid etc..... I'll get a build and assembly - tune run thread soon.
Any of you running LS3 top-ends with Cable throttle bodies? What did you do to mount the cables on the LS3 throttle bodies, and what cables did you use? LS1 brackets don't look like they'll mount. Thanks.
