Having what I believe is a miss in the engine when the engine is under a load. It sputters slightly and I can feel it in the car. Went throught he fuel system, changed plug wires, change plugs and now am at the distributor. The motor is a 292 with the stock cam, Blue Thunder intake and an edelbrock carb. 5-speed manual trans. The distributor is the original from the 292. I wanted to upgrade anyway so based on what I have, what distributow would work best and hopefully take care of this miss I have? Thanks!
