64 1/2 D Code Coupe,
I pulled my #1 plug to determine TDC using the Kelly tool that she posted. I haven't put to tool together yet but I thought I'd post a picture of the plug after 2000 miles. The gap is at .035. I have a Pertronix Flamethrower III coil and Ignition module. The plug is an Autolite Platinum AP 45 in my 289, bored .040 over, 1.94" intake, 1.6" exhaust valves, on stock C4OE heads with threaded rocker studs and a Crane energizer cam with .456 lift exh/Int. 110 lobe sep, Autolite 4100 1.08 carb.
