Hi:
I've had a long, on-going saga on my '93. Dropped a rod after buying it and putting about 3000 miles on the original engine. After pulling the engine, my tech said it was really not salvageable, or practical cost-wise to rebuild. Found a '93 LT1 engine with 52k miles that my tech inspected and listened to before buying for me and he's getting ready to drop it in.
He's asked me if I want to do anything with the optispark while he's in a position to do something. The 52k engine is running great with it's current stock opti; my old engine (103k) looks to have an optispark my tech thinks is a 2nd generation or model from the model number as my old engine has some serious mods and I bought it from a guy who was a gm tech.
So I'm wondering if I leave well enough alone keeping the opti that's on the 52k engine going in, and have him make sure the water pump on the 52k engine is sealed well, or to replace the seal. Or, I could swap and put on the opti from the old 102k engine. Or, I could go with that $500 aftermarket opti which seems to get mixed reviews. Or I could go GM replacement opti.
Thoughts? My tech is in Milwaukee, I'm in madison - thanks
