1976 C10 with 454/400 has a problem maintaining the speed consistantly. If set at 60 it drops to 55 or less than surges back up to speed, drops back down, then accelerates back up, and repeats the cycle.

Can anyone tell me what might be causing this (calibration perhaps)?

Any info is greatly appreciated.

Thanks!
