If it were me, I'd go with the MSD.

I don't have an engine with an "Optispark" distributor, but I do have other engines which use MSD parts. I have an MSD distributor in my Big-Block along with other MSD parts in the engines of my other three Vettes. I've always had good performance from them. While MSD is not what I'd term low-priced, they are not over-priced and are good values becuase of their performance and durability.

your so kind to reply

I'm hearing MSD, e.g. ABITS, and "Petris Enterprises" that sells a vented version with Mitsubishi guts

You have experience of an Optispark replacement ? Can't tell what is best from the car craft article

Back when I had my 94, I replaced with a Delco Opti. Within a year I started having problems, "It can't be the Opti, I just replaced it with 'good' parts". Guess what it was? I chased that problem for weeks, even had the resident masters here scratching their heads. Ended up, the Delco cap was crap. I bought an MSD and had it installed and never had another problem with it to the day I sold it. Go MSD!

Before installing water pump, modify the water pump by drilling and tapping weep hole for a hose barb, then route rubber hose from hose barb down to below engine block. That way, if the water pump should blow a seal in the future, the resultant water will not hit the Opti..

PS search all the forums about the Opti reliability from the various sources.. apparently experience / opinions vary widely..:ugh
