Hi Steve, my name is Doug Duhamel and you did a rebuild on my sons 79 trans am (great job) question I have the turbo 400 out of my 68 gto it had sat for twenty years. After filling up it did work but leaks about every place it could . So what do you suggest I can drop off to you and I want keep it close to stock maybe mild BM shift kit maybe not, have the dyno numbers on engine that I'm putting in so help on torque converter selection would help.
