Its been to 3 shops and none of them can tell me anything I HATE LT1 IGNITIONS!!!!!!!!!!!!

But, I am going to replace the ignition control module, the computer, and get it retuned. If that doesn't fix it then I'm parting out the engine and doing an LS1 swap.

 

just the fact that so much ionized air and humidity build inside it with that much rpm. especially on the non-vented units. and adding a high power coil adds to it, like MSD or 300+ modules. plus the coil is limited in how much spark can be attained from just one coil. it doesnt have time to fully charge before discharge. i dont remember where i saw it but i know i did...which is one of the reasons why i bought the ltcc setup in the first place.

also, i'm not saying that the opti isnt capable, just the majority of them arent. there are a few freaks out there...like some said about my 14 flat bone stock with a paper air filter wasnt possible...i did it and i know i did.

with rotor removed you remove everything bad about the opti. you remove the ionized air, you remove the crappy coil that loses discharge capacity at high rpm, you remove all the misfire issues when there's high humidity or water involved, and you remove the fact that there's only one coil vs 4 or 8.

 

if you get rid the the LT1, PM me and let me know a decent price, and you may have a home for it

 

Check your dowel pin length on that hotcam?

 

Bad ground connections can cause all sorts of gremlins. I would disassemble the stack of ground lugs on the stud on the passenger side wheel well, and clean each one. Also, remove the stud and clean that. If this doesn't solve the problem, at least you've removed one possible cause (and it doesn't cost anything).

Also, perhaps you already did this... go to a shop that has the ability to scope your ignition. This will give you a complete diagnostic of the high-voltage portion of your ignition, including the individual plugs, wires, etc, everything. You can probably get this done for $50 - $75.

If these two ideas don't turn up anything, then I think chasing thru the steps in the factory manual is probably the best bet.
