Just curious if anyone has done this to their 3rd gen. Getting ready to start on mine this weekend or next, just depends on if my shoulder cooperates or not. I have all necessary parts except for the crossmember. I have the Spohn adjustable torque arm that goes between the differential and the transmission crossmember with a drive shaft loop incorporated. Before the swap I had a TH350 with 4200 RPM stall converter in it and the cradle that mounted directly to the trans. This also allowed me to use a stock 4th gen aluminum drive shaft. How much difference is there in mounting location between the TH350 and T-56? Spohn makes the T-56 cradle, but if I can just modify my current one I would rather do that.

Thanks in advance, any and all help will be greatly appreciated.

im running a t56/ls1, i like it, you might need to do the "drill mod" (google it). im not sure about mounting location, since i didnt swap the trans (previous owner). you should enjoy having 3 more gears, well, one more gear and 2 over drive anyway.

I feel as though I am taking the easy route, LoL, but I am going to call Spohn and order the T-56 crossmember for my torque arm. I could spend the time and modify the one that I have from the TH350, but I really want to get the car together and running as soon as I can.

check into the "drews" crossmember, look around there on ls1tech or TGO, it has two humps in it to allow exhaust pipes to go through....very nice

If you have the LT1 t-56,you shouldn't have to do any mods for it to bolt up to the engine.I used the Spohn cross member,and didn't have any problems (besides the cross member hanging down a bit,and my car was slammed.So speed bumps were a *****)

I'm using the LS1 T-56, already have all of the components for that part of the swap. All I am needing to do now is get it into the car so that I can figure out what I need to do to modify my existing Spohn torque arm from the TH350 mount location. I would like to modify the current mount instead of buying the T-56 mount, at least save a little bit of money.

Plus with air ride on the car I am not too worried about scraping anything.
