I am about to order the dizzy upgrade with 8mm wires, a 4.0 head with valve cover, and haven't quite decided what carb. probably going to be the 2150 so I don't have to bother with swapping intakes like I would have to do to place a 390 cfm 4 barrel on there. is there anything else I should plan on doing while replacing the top end ? water pump, alternator etc. is all new( ish ) so I really have no reason to replace those at this time.
