Just give Speartech a call he'll answer all your questions. A th350 behind an LS1, good luck.....

As far as wiring speartech makes direct plug in harnesses, or you can go through the FAQ sticky or get wiring diagrams and modify your own harness

To bolt up a TH350 you either need a torque convertor with a LS1 face(most aftermarket convertor manufacturers have no problem doing this) or you can by the GM crank spacer and longer bolts.

Built my own Harness, have it in 2 cars now that run, and I am doing everything else that is needed to drop in a Stroker LS2 into mine. It's not that hard really, it's all there and pretty straight forward.

why do you say that? not a good choice for a tranny?
the tranny is gonna be very well built to handle some power. trans brake and stall are gonna go in it too..

ls1 is just better matched with a computer controlled transmission. Easier to get shift points and **** together.

No the trans is fine it just seems a bit archaic (no overdrive) to put behind an LS1 unless your building a track only car that's all.

Do not do it. My friend did this swap and he's still ironing out the kinks after well over a year.

You can go ahead and give it a shot but it's gonna take a lot of work.
