Gump is correct. Under section 8 for Stock in the rule book:

DISTRIBUTOR
Any battery-operated, stock-type ignition permitted. Crank trigger systems prohibited unless OEM distributorless ignition. Distributorless ignition must retain OEM number of coils. See General Regulations 8:3.

In this case for your LTjuan the Opti is considered distributorless and a crank trigger is permitted.

One of the issues with the TorqueHead is the multiple coils. I don't know why you would want them over a single coil, but that is beside the point. Your combo only came with a single coil (it is plenty) and that is all that is permitted.

I will add that a GOOD aftermarket ignition box and coil is worth the investment.....

Not really concerned about the multiple coils.
Do not understand NHRA’s reasoning but that is the rule.

It is a nice bolt on system and ECU easy to tune.
Our B-Body clubs like them.
Especially the Boosted crowd.
Agree single Coil is enough.

Until this weekend was fine using TunerCat for ODB1 PCM.
Been a 15 year labor of love learning most of the Files.
Excellent ECU. Opti is reliable.
Just discovered it’s limits.

Thanks for the help.

I use the Holley Opti replacement and I am not aware of any limits I have encountered so far. Can you elaborate?

Dan,

With all due respect, in lieu of trying to reinvent the wheel. Listen to the guys that are running the Opti-Spark system. On the long run, it will be more reliable, better performance and cost effective.

I am !!!!!!!!!!!!!!!!!!!!!!!!!!!
Having a fight with Pat Cvengros over this RIGHT NOW !

Dan
Where did you get that information from?
I disagree since it clearly has a distributor with a single coil.
Pat Cvengros - Pacific Division Technical Director (626) 250-2295
----------------------------------------------------
My response !!!!!
Found out mine is considered a Distributorless System
So a Crank Trigger is fine..
D
----------------------------------------------------
Previous Conversation;
No, crank trigger ignition systems are only permitted on distributorless ignition systems.
If you switched to Super Stock you could run a crank trigger with the Opti spark distributor.
Pat Cvengros Pacific Division Technical Director


Pat thinks the Opti s not a Distributorless system !
So I am confused.

Needs some help here !!

Dan

Follow up EMAIL from Pat !!

Dan,

Unless you have documentation from Chevrolet stating it is a distributorless system it’s not; so a crank trigger would not be legal.

1. Distributor: a device in a gasoline engine for passing electric current to each spark plug in turn.
Pretty clear to me you don’t have a distributorless system.


========================
SO I am confused

Just sent Pat KRATLIF's response.
Pat's response is below.

Thanks for the heads up, we will have to look this weekend at Pomona.
As I mentioned previously, unless you have documentation from Chevrolet stating it is a distributorless system it is not.

Then sent GUMPS response...

You can believe who ever you want,
I’ve answered your question based on how NHRA officials interpret the rulebook.

Crank triggers are not a legal option for the Opti Spark.

So what you are saying is that you just rocked a boat that was on calm seas....

If enforced under this interpretation, this would park pretty much every LT car running Stock Eliminator! I'm pretty sure that Holley doesn't have a harness. I don't know about the other systems.

Keep being AWSOME Dan!!
