I have a new crate engine for my 76 camaro. I am putting in a rebuilt TH350. Is there a better option than a "stock" torque conver the rebuilder wants to sell me? He will be installing the transmission and I can take my choice of Torque Converter with me. There is no fancy cam installed, and I don't have time or money anyway; but I'd like to put the best TC I can in while the tranny is out. What can I get away with in my mostly stock ENG/Trans?
