I don't have the faith in MSD that I used to have. It seems I hear more and more fellows complaining about the product and since I retired, I no longer have my hands in the hotrodding sport, so I have no alternate to recommend other than using an HEI. If I had to build a motor today, I'd probably use an HEI from Davis Unified Ignition (Performance Distributors) products.
