So I’ve been tweaking the tune up on the 422 for a week or so now. Got things pretty much in the ballpark as far as timing and fuel. She likes to idle right around 950-1000 rpm at 20* static timing with an FBO plate limiting the mechanical advance to 34*, all in by 2200rpm. I’ll be attempting to use full manifold vacuum for the vacuum advance tuning to try and maximize fuel economy and drivability on the street.
Planning to spend a day this weekend at the drag strip to do some more tuning and have some fun. Really anxious to see what numbers it can lay down. Any guesses? Previous best with the tired old 318 was
