Just bought a one-owner 71 Datsun 521 pickup for $100, it runs but with carb trouble, and needs a new master cylinder also. I was going to rebuild the motor and was wondering if anyone knows whether or not performance parts are available,.. looking for larger diameter pistons preferably flat top, bigger cam, etc ANY HELP WOULD BE GREATLY APPRECIATED!
sorry,. Im a noob,. accidentally posted in 520
