back to getting on the build. Reminder...mild performance 350...carb, cam, headers,intake. debating on what trans would be best for my application. Got a donor 700 r4...no history on it and it needs a converter. Was looking at the possibilitiy of a shift kit and maybe a brake. I see alot of turbo 350 and 400 already done from reputable people for decent prices....are the 350&400 better or easier to work with?...seems performance parts are more accessible..what do you guys think?
