I'm a little biased, and perhaps a little more capable than some. Don has a decent product, but to be honest, the biggest improvement is a result of the right ignition curve. And that can be done by someone who knows a little, has $20, and $10 worth of timing tape and advance weight springs. I ran the Std Ignition modules for years with 175hp NOS kits and factory distributors. Nothing fancy, but he gets a premium price. I consider it a well scienced out factory ignition system. The MSD, Crane, Jacobs, and other multisparks are way ahead in terms of potential. Add in an rpm limiter, and the choice is clearer. The old stand by for me is a Pro Billet distributor, MSD6AL, and Blaster II coil. Many setups in action for years. Stable, and money well spent.
