Trans just got rebuilt prior to the trans swap. Maybe 600 miles and I have a 2 year warranty on it. Engine is running OK now, but I'm looking at being prepared and would like to spread the cost out over time.

I didn't know that I would need to run a fuel return line, so that's something else I need to look into.

Basically looks like my list is fuel delivery system, vortec intake manifold, probably a new carb, flexplate plugging the crank sensor hole, timing marks, and long water pump (I have a short one now, which is new) and making a rear AC bracket.
