OK overqualified guys!!!....lets be real. Gapping at .045 will have no noticeable effect on his engine power. The theory is right, but it's not something one can feel in the seat of the pants. At least, I never have been able to tell anyhow. Matt, you lost power because you retarded your timing. The higher initial timing you had before is where you picked up power. Im assuming your 8* btdc is without the vacuum advance? Im certainly more into big blocks than small, but we usually run 16 or 18 initial timing. Im not sure you can get away with that much, but if you can, it will run really strong. Maybe more small block guys will chime in. I would think you could run at least 12* without problems. Running the best fuel you can? Yes, messing with your mech. advance is your next project. You want your total timing all in by about 3K rpms. If your mech. advance picks up quicker, it will help with your power problems too. I would re-gap the plugs too, but in my opinion, that's the least of your problems. John

All I can say is, you will notice it in the seat of your pants when it does it's mis-firing thing

You know I was just bustin on you, right? I am well aware that you know your stuff. By the way, I have a good Ford joke. When the time is right. And what do you mean by 'mis-firing'?
