3.08 gear
Yes it is a 700R4....As to rear end gear, it depends on what you want to do with it....Street car?? Drag car?? Daily driver??(doubt it with a 383, but I've seen crazy stuff) Road racer?? Top speed contender??
3.42 is generally considered to be the best all-around gear for the TPI motor, but if you want a little more punch and don't mind the slightly lower mileage and top speed, 3.73's are a great gearing too.
