I took my '73 Dart w/318 out for a spin tonight and noticed I have a miss above 4,500 RPM only when at WOT. If I keep the throttle below 1/2 way, it runs fine at the same RPM range. I verified the fuel bowls and accelerator pump adjustment with a feeler gauge thinking it was a fuel delivery problem. It had no effect on it. Below is some info on the car. Any suggestions on what I should check next? Thanks!
- Original 318 bored 0.020
- Original heads with larger valves (1.88/1.60)
- Classic Holley 600 (68 main jets, 4.5 Power Valve - 10" of vac at idle, #31 Pump Nozzle)
- Weiand Stealth intake manifold
- Comp Cam 20-223-3
