Re: High compression head and timing?
I have a 7:1 alloy head on my car and the motor is very quiet. Consequently when it does ping, it sounds very loud.
With just a fraction too much advance (9:0 o clock on the advance lever), it will ping readily with just the tiniest bit of too much wellie.
The 41% overdrive F150 gearbox tends to exaggerate this problem too as it will pull up quite steep hills in overdrive, but one has to restrain one's accelerator foot and treat it very gently.
