How do I dail in spark plug gap?
I have a 89 350 TBI and have upgraded the ignition. Now, stock calls for the plugs to be gapped at .35. I am finding that just with a MSD coil people are gapping up to .55. How do I know where I need to be? Do I just start opening up the gap until power starts to drop off? This is not a high performance motor but I am building up performance for increased fuel economy. ThanksFriends dont let friends drive fords!
Damn, that's something I didn't want to hear. I'm glad I got to meet him and Rosie and Rick. I'm proud to have had him as a friend, RIP Johnboy
