I have been very lucky with my t-bucket build so far... I've had very generous people give me some fairly expensive drivetrain components and I'm very grateful, since I don't have a whole lot of $$$. So here's my issue... a good friend gave me a 350 SBC and a transmission. The engine is very straightforward but the transmission was a mystery to me, not being a transmission guy and all. But I could visually see that the tranny bolt-hole pattern wasn't going to match up with my SBC. After much internet searching and education, I've come to find out that I have a TH400 BOP (Buick, Olds, Pontiac) transmission which happens to be in very good shape. I've also learned that I need to buy an adapter to make it mate up with my SBC. Have any of you had this issue and used this type of adapter? Summit Racing sells a nice thick adapter that seems would work ok, especially since I have not yet welded my engine and tranny mounts onto my frame. Since the adapter pushes the tranny back about 1/4" to 3/8" from the engine, is there anything I need to worry about with regard to the torque converter and all? As I mentioned, I really don't have the $$$ to be swapping this tranny out with a Chevy version so I really want to make this tranny work on my t-bucket. Thanks for the help!
