I am looking to buy a th350 out of a 78 oldsmobile. The guy says it has a bop adapter for a gmc. I was just wondering if its worth dealing with the adapter plate to fit an ls engine or just find a th350 out of a chevy. Also i am pushing about 480hp to the wheels now and am going to spray a 250 shot. Will a th350 hold up to this hp? I was going to take it to cooks in sc to have him rebuild it.

Anybody, at that power level is it just worth throwing in a th400?

we ALWAYS recommend the TH400 over the Th350! Much stronger and more reliable unit! Especially if your going to be throwing 800+HP at it....

If you have neither and are buying a complete unit...Agree....th400

Yea I'm doing a t56 to th400 swap, trying to figure out about how much it's gonna cost me. And if I should just buy a th400 and have a local shop build it

Just had my th350 done (pulled from my car) and it was cheaper to build than have them supply one, and me turn in mine for a core, but only by like $50-$100 ?

Anywho, I stayed with a th350, mainly due to it's what I had and no swap costs....plus it will be fine at my level and being a comp manual build.(higher line pressure/better clutch holding)

So, I guess you could go either way (ask them if they have ready to build).
