I have in my shop right now a 70 with a 327 and a 3ott. I am heavyily thinking about adding a t-5 5 speed to have a overdrive. The auto thing has been done to death. I have two others of this style truck and one is a big block and the other will have a smallblock both with autos. So, to be different , I am thinking of the t-5 to the piont that I have bought one from a v-8 camaro and a S-10. Look ath the FAQ section there is a write up on it. But, if driving much in town with a teen driver is gonna happen I think you might want to go auto. Look into a 700R4 or a 200r both have the overdrive that will be neded to get better mpg. The tune of the motor is impearitive to get the best mpg's timing set right valves set right carb set up right andas mentioned the rear gearing is factored in as well. If you have 4:10 gears just to drive around do you really need it? your son may think so when he romps the throttle. Higher gears like 3:42 or even 3:08 make more sense. Welcome to this site!
