No need to pull the engine. Should just have to pull the radiator. If you don't want to attemp this I fully understand. The other upgrades should be fine. The rear is probably a 2.76 so upgrades won't make as big of a difference.
That’s really good to know about the radiator pull! In that case, it seems like a fun summer project - and more justification behind throwing that higher CFM carb in there :D
