Ls1 Third gen guys Im going to put a TH350 into my 3rd gen ls1 car, what crossmember do I need to use, can i use the stock from my 700 r4 or do I need to buy one, I need to know Im gonna do this in about a week, swap out my 4l60e for a th350
Might give Spohn a call... Are you going to still run the torque arm? If so you will need a way to mount that. TH350's dont have provisions for a torque arm...as far as I know.
Anyway, here is his TH350 crossmember/torque arm combo.

It doesnt say if it will work with the LS1 set up, but since the LS1 sits in about the same position as the regular SBC...it should work. Its pricey, but it will offer you a bolt on solution and adjustability.

Well...Im not real real familiar with auto trans clearances...especially with the TH350, so maybe someone else will chime in. Or do some searching. But I will tell you that the spohn crossmembers tend to take up some space for the exhaust.
You can always build your own... then maybe just get his toruqe arm and mount it on your x-member. Thats what Im getting ready to do, except I have a T-56.

I bought a torque arm for my th350 conversion that has a plate that bolts up to the floor pan. The arm is probably two-thirds the length of the factory arm and is double adjustable which "should" help move my instant center back and hit the tires a lot harder. I'm not sure about the transmitted noise to the car but with spin-tech duals I'm not sure it'll make a huge difference anyway for noise. I'll need hearing aides in a few months anyway!!
