I need to see if anyone has a non-vented Opti-spark for sale. I'm really frustrated with my LT1 right now and I'm it is really testing my nerves. The last thing I HAVE to try, from looking on sooo many forums and having my car in several shops, is the OPTI...what a dumb invention...(no wonder the LS1 went to individual ignition) But anyways I gotta start somewhere, so please reply if you have a new/GENTLY used Opti-spark for a 1994 LT1.
