'68 302 4bbl 4 speed.
Took the family to the inlaws today, approx 20 miles, engine ran great.
When we started to come home 3 hours later, the engine hesitated and missed real hard, at all speeds. It felt as if several spark plug wires werent connected, but I checked, and all were connected properly. The car has been great since I installed the distributor about a month ago, I have put over 500 miles on it since then, so I dont understand in a matter of hours why she went from running great to running like crap.
It has a Holley 600cfm , which was purchased new about a year ago.
I checked and didnt find any vacuum hose problems, nor any loose wires.
Anybody got any ideas??
