That's how I feel. But that's the way it is. I only ran 117 with it at 36. I them bumped it to 38 and ran 119. Then I bumped it to 43 and ran 121.

Here's the video from that day and yes, that is my Cobra racing my Chevelle. My brother drove the Cobra in the first pass and then the Chevelle when he I raced.

I guess these guys may not know I have a Sun Dizzy machine.

Wasn't that the Ford ignition that they used in the early 80's?

The GM Optispark is an optically-triggered ignition distributor used on the LT1, LT4 and L99 engines.

I just looked it up and it was the Duraspark ignition that I was thinking of.

That was crap. Same with the "Thin Film Ignition" POS.

Ok, so here's how I see it.

I'll pass on the Multispark for now, because it's the kind of thing that can be easily inserted into the ignition system later if it proves necessarry.

So as I understand it, we have two ways to go

1 - Dizzy and External Coil
2- Coil in Cap

Right? What are the pros and cons of those setups?

The only advantage is the HEI will be cleaner to install because the coil is in the cap. That's about it. Phil and I were looking for an HEI at the Hot Rod swap meet in Long Beach last weekend but he didn't like the new ones that they had there. They looked cheap (remember he has worked Chevy's for the past 16 years) but then again we did see brand new ones for $70. He ended up buy a used stock HEI for $5 so he could repair the stock one he has already.

That's that stupid TFI ignition module POS that plugged into the early 80's HEI dizzy. My 84 Lincoln had that. There was even a class action suit about it.

Don't forget the spacing of the contacts in the cap. The wider the better.
