Are you throwing any codes?
I'm running the Delteq -- using 4, dual-terminal 'waste-spark' coils off of the Cadillac Northstar motor. I was one of the few rare cases that had a HELL of a time getting it to work right, but in the end, it finally worked.
Bob Bailey's LTCC uses 8 LS1 coilpacks, which has more dwell time, but they are literally half the mass of the Northstar coils. I believe the LTCC also has provisions for a rev limiter and retard feature, but only one can be used at a time.
There are pros and cons to each -- just have to read up and decide which one you like. These kits will only help if your cap/rotor is wearing out. Both will require a working optical-portion (rear section) of the optispark in order to function. A lot more wiring is involved with the LTCC -- the Delteq is strictly PnP.
Then of course, there's the Dynaspark unit, the new MSD unit coming out, or you could go with an aftermarket computer & machine the intake manifold to run a standard SBC distributor...

Although I have not had any problems with my Opti, with over 157,000 miles, I don' see why anyone would really want to go with something else. Think about it, why pay the money to $hitch to something that still uses part of the original Opti. Its not the cap and rotor that is causing "all" the problems with the Opti that everyone is having. I think it has just gotten a bad rap and that has been the very first thing people blame for their problems. I have never touched mine, maybe I am just lucky.

I have never touched mine, maybe I am just lucky. good point. im waiting for a true crank trigger type setup that uses the stock pcm. Joe O still uses a stock opti w/ an msd 6al (with gen 7 dfi) on his 8K rpm 383ci low 9 sec NA LT1. |

The theory behind switching to an LTCC, Delteq, or a distributor in the rear while still running the opti for triggering, is to remove the high voltage from the Opti. If spark distribution takes place somewhere other than inside the opti's housing, it's life can be greatly increased, or at least, this is the theory. If high voltage damaging the opti's aluminum trigger wheel is in fact causing them to go out, then this theory seems to have some validity.
I was having problems with mine when it would rain, or when it was very humid, so I've decided to eliminate mine alltogether with a DFI dual sync distributor.
Who's running an LTCC or a Delteq? If so, how is it working out?
