[Jim Downard]

Hey Ron,
Jim Downard here. Did you choose to ues the Ford Duraspark because of the CR wiring harness. I was running the Duraspark II ignition and dumped it because of various problems. Screwy timing advance kept making my engine run hot. I would pick up a miss (sometimes) under a heavy load, but always on the right side. I found a loose ground in the distributor, and I also found that the Duraspark II required a specific coil. With those items remedied, I still had a hot running engine. I bought an MSD 6AL ignition, MSD pro billet distributor, and an MSD coil. Problem solved. Engine runs cool, never misses, and runs stronger than it ever did. It's a tough pill to swallow, but dump the Duraspark and go with a quality performance ignition. You'll never regred the change.

Good luck,

Jim
