Good fit. No issues. Comes with adapter cable that you may not need. Didn't fix my issue, but doesn't seem to cause any issue. This has the vent and vacuum line to prevent the oxidation

I used this Opti on a 95 LT1. It fit and worked perfectly, except for the pigtail to the PCM. I had to use the old one. Possibly, the connector is current for 96/97 applications that use OBD2. Nonetheless, it's an easy fix. Send it.

I never used it and returned it. I’ll give it 5 stars anyway since it looked like a quality unit.

Unfortunately, this has turned into a nightmare. I believed I had made a good purchase until I got a P0372, weak timing signal. Only to stall out and get stuck. I would not recommend this. I am on the verge of spending $350 on a Delco Reman.. not sure what else I can do at this point. Good luck to anyone else with an LT1.

Looked like a good solid optispark. But wrong wire harness for 94 LT1 and no spark once installed and I can't return it for a new one. Can't call it junk but definitely defective.
