## Description

.

Review: Very nice and works - I mean these have been around for a long time and have been proven to be worthy.
Review: Fantastic performance - I installed this on an older 95 LT1 v8 it really helped give it a boost in spark and car runs well. Note this was not a stock engine. 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 C***O on 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.
