| New 428CJ with high RPM miss... |

I recently installed a 428CJ in my 67 Shelby (25 miles ago). I am experiencing a high RPM miss (around 4300 rpm on up). To me it feel/sounds like ignition looking for advise to solve the problem.
The specs are: 428CJ bored 40 over with Edelbock heads with autolite plugs with a gap set at .042. FPA headers, Blue Thunder single four intake with 750 Holley carb (1 year old). Stock mechanical advance distributor with Pertronix ignition, Pertronix coil, 8.8 Accel wires. Most of the ignition components and carb are around a year old. timing is: initial 14 with total set at 34. Dont think its carb related and during the rebuild installed a hi volume cater fuel pump and I am showing 8 pounds of pressure at idle. I checked the air gap on the Pertronix last night and replaced the rotor and cap. Miss is still there.
Any help you can provide would be great.
Morgan
