Good luck!

note: the delteq still uses utilizes the the "opti" part of the optispark
Well yes, that's true, but it eliminates the cap and rotor which are from what I understand the main problem pieces. I highly doubt a delteq setup with a sealed up opti to keep water out of it would be any more problematic than a gen I or gen III ignition setup. Maybe I'm way off base and if I am I would like to know.

HHHHMMMMMMM, i heard i can somehow use a LT1 pcm and convert it to a GEN III without a PCM swap, is this true??? Hell, if i can use a EFI setup on the bastard with a GEN I i would even do that...any suggestions??? Think i will use a ZZ4 cam, they are only 90$ and would be great for a DD.

For those who are not quite in tune with the LTx system I will say one thing. The OPTI "IS" the foundation of the entire system. With out it the system is usless

Delteq and LTCC have been tried and semi successful.

The DELTEQ would not run in any way shape or form for any period of time and Bret(PEPE') had the same issues with the LTCC.

BOTH of which still need the OPTI to work.

the best alternitive is to convert the intake to use a MSD short Crab cap for crank trigger. The down fall is most times you can not get the distributor back out with out pulling the intake or Engine.

I am still looking at this option when i install my Hogans

Well, we will see, i am just going to do whatever works for me that is convenient. **** on the opti, i am done with it, i heard you can do some splicing into the stock PCM with a LS1 distributor setup, but i dont know the details.

You mean the LS1 Coils?
The Signal for them comes from the PCM..there are 4 wires on each side from the PCM.
Pink goes to the Coils for Power, then the different color ones are grounded out through the PCM, that completes the Circuit when it needs to fire that Cylinder.
I don't see it happening with the LT1 PCM..

hes just looking for excuses to bitch about his bad luck with his car, unfortenatly almost all of us had bad luck. When i first build my motor, i was braking it in still only 400 miles, idling in the driveway my crank snout snaped due to too much blower belt tension. First thing that came to my mind thats it i'm going to ditch this Mother fing lt1 for another small block just like it but with no opti

Guys this is an incompetent wrench who keeps blaming the parts he messes up, simple as that.

Far as the ZZ4 cam, had one for awhile, with cats on the car most people mistook it for stock as well as it idled. I really would not bother with it though, especially not in an f-body. The Lingenfelter 211/219 is about as small as I would recommend, that cam WORKS and is far too often overlooked.

Not trying to bitch, just telling it like it is, i am done with the opti AND i have a GEN I 383 laying around so it is a convenience to me.

Seems to me you put the heads on just weeks ago? Perfect opotunity to get dirt in the engine.

What do I know though, I just manage to keep my car up and running FAST. A big part of being sucessful in modding cars is admitting when you make a mistake and learning from it.

Yeeaaaa.....too bad from past experience and learning from mistakes i actually cleaned the top of the engine before i ever took even valve covers off. Nice opinion though. I love admitting to my wrongs so i can share the info with others and keep them from having the same trouble.

Well, i might go back LT1 if it seems to hard to have a distributor in the back, what is the minimum mileage of a used LT1 you guys would recommend for installing a hot cam. I will definitely go with a bit more ***** in the valve train area while i am in the process.
