It has a large cam, ported heads and Headers.Another note. I also have the MSD coil but still use the stock opti spark distributer.one thing that makes a big difference is using the correct oil seal on the distributer once I finally installed the proper oil seal that looks like a standard oil seal all the problems with the opti spark went away after cleaning the oil out of the inside. Don't need to waste money on a 595.00 MSD distributer. Iv'e only heard bad reviews about them. this opti spark distributer was only 45.99 ### ⭐⭐⭐⭐⭐ Awesome product *by on Reviewed in the United States June 13, 2013* I received DOA MSD control boxes from Amazon, however the third box I received finally did the trick! At first, I believe it was the installation or how my car was pre-wired, however after calling MSD and troubleshooting with them, I was convinced it was the MSD box. I have a smoother ride, more power/torque felt in the low/mid range, starts easier and faster (it already started great, but you can feel/hear the difference with the digital 6AL). Gas mileage, surprisingly, increased. Well worth the investment.My car is a 1973, Datsun 240Z with triple weber carbs, headers, and pertronix 1 elec. ignition. Please note I changed my Pertronix Coil to an MSD coil during troubleshooting before realizing the Box was the culprit, so not sure, but I doubt if the Pertronix coil is compatible with the 6AL. ### ⭐⭐⭐⭐⭐ buen articulo por su valor *by on Reviewed in the United States June 2, 2026* muy buena trabaja correctamente ## Frequently Bought Together - MSD 6425 Digital 6AL Ignition Control w/Rev Control - Red - MSD 8202 Blaster 2 Hi-Performance Coil - MSD 85551 Pro-Billet Distributor --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/81800542-msd-6425-digital-6al-ignition-control-w-rev-control-red](https://www.desertcart.in/products/81800542-msd-6425-digital-6al-ignition-control-w-rev-control-red) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-08-24*
