Scored my 74 with a Goodwrench 350 and po had swapped late version tpi on. I ran mine with a nos painless perfect ecm. It's a reboxed GM mefi4. It's a hoot with the 4spd. You just can't shift fast enough. Next up is a set of vortecs, vortex tpi base and a cam. Not sure whether I go GM 395 roller of comp 260h. It'll be a blast right up to about 5k. Ought to make torque for days.
