Sam, if you don't like the way the 4 speed is installed, I would go with a T-5. It is a fairly easy changeover and the shifter comes up in the middle of the floor (which means patching up the previous hole from the 4 spd) Headers are nice on these and the 2 carb should be a nice setup. I went with a single Holley from Stovebolt on mine. Runs excellent in the shop as it is also going thru a rebuild. Ready for primer and paint now, hopefully in the next month or so we will see how it runs. Just don't go ripping the truck all apart before you get a chance to drive it or it will end up sitting in pieces and you will lose interest in the project. Good Luck
