Hi Bill,

Thanks for the suggestions. Yes, it is an MSD 6al, MSD distributor 8594 and MSD coil 8222. The backfire occurs when first accelerating from a stop - the engine runs rough for a couple seconds and it is during this time that it sometimes backfires loudly through the exhaust - always driver's side. Once the engine smooths out after about 2 - 3 seconds it runs fine and continues to run fine until returning to idle again.

I put a new dist. cap on, although the original was still in good shape - I've cleaned the cap contacts and rotor regularly and coat with dielectric grease. Will start checking all the above.

Thanks again,

Kevin
