Stop in for a cup of coffee

Hey keuth want to help a guy troubleshoot a car in york? FBBO guy

I'm Curt from Red Lion, PA. I recently bought a nice '67 Plymouth Satellite w/'78 400cid w/Edelbrock Performer intake and 4bbl carb. Shorty Headers. Mopar Performance (Orange box) Ignition. Compression is good (and even) all 8 cylinders. Problem: Car has an unidentified miss and stumble. Apparent across the range.
I went through carb thoroughly; floats, jets, metering rods. I replaced spark plugs, cap and rotor. Still has this miss. I've been advised to look to the wires as the issue, or next step tracking the elusive miss down. Currently running Taylor Pro 8mm wires. You are highly recommended. Can you help? Do you have suggestions? Do you make-up wires? Thoughts?
Much appreciated.
Maybe , but I would call you! :rolleyes:
