I thought they only made the HEI one for our trusty inline sixers, pretty neat i wonder if it operates better then stock, or if its just like a recurved dizzy for 265 bucks lol
is it just the duraspark style distributor??, or is it the HEI style ?
Duraspark and HEI are the exact same technology, the difference is HEI has the coil built into the cap. You can see that's obviously not the case with this particular unit.
I also run the Davis DUI (DUI-39820BL on summit) and have nothing but good to say.
The only gripe i have is the live wires are too short if you are not stabbed into the right place, seems to be vac pod almost touching engine to rear of dist. that and the covering is a dirt magnet lol

Hei was put out in both styles, integrated unit and external separate coil unit, although these were not nearly as common.
I wanted to know if the hei module was inside this unit or external or even uses an hei module at all. Looks like the OP questioned, just a recurved dist. The Summit description says an Hei style cap.
So far no one has answered that.
A real GM HEI module can be triggered a number of ways and the reliabilty of the module is the prime factor. Spinning up to 10,000rpm with a fancy race module is a silly claim for a 300 Ford.

The large Ford distributor caps are considered HEI style caps. They are listed the same way when buying plug wires for a Ford.
Really? It's been done Here's a 240 that spins over 9,000 rpms. Not everyone runs a mild 240/300. Of coarse most of the race engines run mags. But I'm sure that's just their blanket description to cover all the Duraspark distributors.

I have never heard a Ford distributor cap referred to as anything other than a Ford distributor cap or a Duraspark distributor cap. It makes no sense for a Ford distributor cap to be referred to as an HEI cap because HEI is originally a Ch*vy-branded term. Whoever you have heard do that was probably using it as a colloquialism to simply mean "electronic ignition."

The large Ford dist. caps with male terminals and plug wires for them are listed as HEI or HEI style. And it's a colloquialism for High Energy Ignition. I don't like it, because to me it's a gm term too. But it is what it is.
Where are you seeing Ford Duraspark caps listed as HEI? I've never seen this before (doesn't mean it doesn't exist). Just because it's written somewhere doesn't mean it's an industry-standard reference.
The word "colloquialism" refers to an informal generalization, not an acronym. If you're seeing some website or parts catalog refer to a Ford Duraspark cap as "HEI", they are most likely making a generalization that it's intended for electronic ignition without specifying the manufacturer. And, they're generalization would be misleading.

Whatever I'm not going to sit and argue about it with you. I was replying to tiaps question about why the duraspark distributor had the HEI style cap listed. That is the way they are listed, Wrong or right.
The colloquialism isn't "electronic ignition" it's the large Ford caps with the male terminals. Is that better, grammar cop! I don't make the listings I just have to deal with them. If you don't like it go complain to Summit racing, Mallory, MSD, Crane ( if they are even still in business ) , etc.
So anyway, the Ford style dist the OP linked to, apparently as he also referred to, is just a recurved Ford dist for 265 bucks.
So for 100 bucks more, you can get a real self contained HEI from DUI.
A little spendy, but the HEIs are bulletproof and easier to curve than the Ford units.
