I've never had a problem with the opti sparks on my LT1 engines though it is the weak link in the entire design. I'll probably add an MSD box and coil to the system though just to ensure I'm getting a good hot spark.
So you think I'd be fine using 93 octane with a tight quench and a DCR pushing 10:1? That's basically what I'd have with an SCR just under 12:1.
I've emailed Ai to see what they will say as well.
Thanks Scott

Trey, I think so. Keep in mind that the tighter the quench, the more efficient the chamber, the more compression you can run. Of course you have limits on how close you can get the piston to the head, and if you get the quench too close, you end up with piston to head contact. .030 is about as close as most builders dare to go, even with top tier crank and rod assemblies.
I'd go with it, and play with ignition timing as necessary. My plan "B" would be pulling up to the pump that sells E85...
Let us know what AI says. After all, they sold you the stuff.
