Ok ay i am 17 years old and i got a 62 chevy c-10 fleetside last october but didnt start driving it till january of this year. I rebuilt the carb, and got new wheels and tires for it, but i want somthing new under my hood, the engine is the orgianal stright 6, it still has the oil fillter and everything is stock. What would u guys do as a first step to giving this truck more power ? thank you.
