I have a new 383 to go in my 91 coupe next week and am looking for recommendatons for a solid ignition system. I was thinking of a DUI distributor and some sort of MSD box. Let me know your thoughts, thanks!

There isn't a thing wrong with the stock HEI ignition. If you have money burning holes in your pocket and you absolutely have to get rid of the money, the only better ignition system would be a multiple spark capacitor discharge system. MSD makes them and you will need to replace the center button on the distributor cap because the stock button is carbon and the increased spark current will heat the stock button up and destroy the cap.

I thought I would replace the original distributor because it has 180,000 miles on it.

At that mileage I would replace it as well.

I drive my 87 vette every day and it has 212k miles on it including the distributor and it works perfectly. I did have to replace the spark module.

Damn. Over 200,000 miles.... My car wont make it that far.

Race Prepared

MSD6AL with Blaster Coil - available as kit from TPiS. Stock system is weak & you will find those weaknesses with the 383.
