1968 GT500KR carburetor tuning
« on: June 21, 2022, 10:22:30 PM »
Hello all,

New to the forum here and wondering if anyone has some input on this. Iím restoring a 1968 GT500KR and attempting the tedious process of concourse. I am currently in process of restoring the Carburetor but before I put the metering blocks on want to make sure Iím putting original size jets and power valve in. Does anyone have information on what these front and rear were when the cars were delivered?   :o  Thanks for any help/direction you can provide.

Justin

66 front. 79 rear. 6.5 power valve is stock. I run 68, 81 in mine. Seems to like it better but I do have a slightly bigger cam in my car.
