MSD Opti Spark
I seem to be having the same skip/miss/cutout at about 5000rpm. Sometimes i do get enough to get it to 5800rpm so it will shift but more times then none i have to lift to get it to shift. I'm not getting any codes, could the opti be some of the problem??
Non vented I think was 93-95 lt1's ,vented 96-97??
Yeah I have burnt up 3 optis in my 396 stroker in 3 months , so the boys at Rev xtreme have made som adjustments to it and we will see. Either way I plan to convert to coils by year end!

Can you upgrade the vented into a 95 LT1? My friends Caddy with the LT1 seems to be having a problem and I have a feeling it's the opti. I had the damn near exact problem with my 94 Z. Just wanted to know if they are interchangeable.

The caddy will already have the vented. To convert a non to a vented, you need a new cam, timing cover, distributor, harness, and vacuum line.
So, has anyone even received the MSD Cap & Rotor yet? I freaking doubt it since MSD is not showing a release date until March 31. I ordered one through HPE here in Houston after I called MSD to find out it's the whole unit. Internal sensors and all. I have been waiting & waiting only to have MSD put it off again. If anyone has received their MSD unit, please reply to this...
Thanks,

I have a couple of spare optical pickups I keep aside just incase one goes bad I can replace just that part.
