Ignition problem
I recently installed a new 454 in my 71. The car runs pretty good except when driving for about 30 min I start getting a hesitation. I also get a mild poping aout the exhaust. My guess is that my ignition is dieing. I have installed a new alt, coil, points and cond., cap, rotor, wires. Everything looks good. One question I have is with the resister wire to the coil. What happens if the wire is bad or over heats? Could this effect the ignition while running?

Re: Ignition problem (conway62)
Could be, but BBs tend to develope a little stumble or hesitation after they get hot. This is usually carb related, and occurs on both Holley and Rochester equiped cars.

Re: Ignition problem (conway62)
Ok that resistor wire is the positive lead to the coil (from the ignition switch). It prevents the coil from burning up under continuous use. But I think the HEI set-up did away with this for some good reason. I guess what I’m trying to say here is not every year shark used a resistor wire and I apologize but I’m too tired to research this tonight. BTW I don’t think Chevy used a ballast resistor on any shark (in case you wondered). :rolleyes: Anyways the other wire to the positive side of coil is from the starter and is not a resistor wire. It provides a full 12VDC to coil only when starter is engaged - to help start things up.
That popping sounds like a vacuum advance problem out here in California. But then everything sounds alike an advance problem from this distance. :jester Just can’t explain why it wait’s 30 min. to begin unless the choke is in on this conspiracy. Using the stock EGR?
Ya know I had a 350 once that missed badly enough to take to Chevrolet. I had shorting/grounding plug wires due to a sharp-toothed tool I used to remove the wires for tune up. Didn’t expect this so close to spark plug connector. How are your plug wires? Could headers be burning them up?

Re: Ignition problem solved
Solve the ignition problem. Put in a MSD Corvette Tach Drive Dist, 6AL ignition and blaster 2 coil. Problems solved. The car runs awesome. Now if I can just get rid of the Edelbrock and replace it with a Demon, I will be all set.....
