Throwback Automotive (formerly Petris Enterprises)

Chris went out of his way to get me my part. His shop was actually closed for the holidays and he made a special trip to put the part in the hands of UPS. It works fantastic, highly recommend Petrie Enterprises and their brand of Opti Spark. The LT1 in my Buick Roadmaster runs like new again. Couldn’t be happier.

The customer service is fantastic and the distributor I bought for my 95 Corvette LT1 works great! This is the only Opti Spark distributor to get once the original wears out. Highly recommended.

They carry many parts that nobody else still does for our LT1/lt4's, customer service is 10/10 they make sure you're happy and try to get you what you need, if they don't have it they'll see what they can do about getting you what you need.theyre knowledgeable and know what they're talking about. Fast shipping they took the stress out of finding parts that even gm dealer discontinued and don't carry

I recently purchased the complete optispark kit for my 1994 Corvette. I received it two days after it was shipped and all parts were included, just as advertised. After installing the complete kit, the car runs better than it ever has in the six years that I’ve owned it. I highly recommend using Petris Enterprises if you plan to replace your Corvettes optispark.

Ordered Opti-spark distributor complete kit for my 1995 Lt1 Corvette. Did job myself. This is the “opti” to get and all the other parts of the complete kit were first rate OEM or better parts. Great stuff and I’m running great again. Thanks Petris. Just want everyone to know that three years later my 1995 LT-1 Corvette is still running great! I’ve had absolutely no issues with the Petris “Opti-spark” or any other parts I purchased with the complete tuneup kit. The Petris “opti” is absolutely the one to get…..I believe it’s far and away the best on the market and probably better then the original. Spend a little more and get the good stuff. It’s worth it!
