Just curious, but how can you tell he has a sniper from just a picture with no words?

I'm all in with Holley... My EFI unit came with a coil driver but I went with their new CD box, coil and hyperspark distributor. I think it was MSD had a hand in with Holley making this setup. The real benefit, it's all plug and play with no installation surprises , no RF noise ... It all talks with EFI, full adjustment w/o going under hood, etc...
With some wiring to figure out, Holley sniper workers with some of MSD's older offerings. Didn't read too much on those guys doing that as I had to start over .
It really added a sense of refinement to the EFI IMO. Like when I dumped the 4 bbl carb in favor and loaded base tune... Wow! No buyers remorse. Now with this, again. So far so good. Not to say I didn't have any issues with Holley, they swapped my complete unit once outside of warranty... Long story. But knowing what buddy went thru with Fitec with non existing customer service , I'd say I was happy I went with Holley.
502! Haven't actually seen one since my dad's 78 Caddy Elderado FWD! Rare bird, even crates around my parts.

That's what I was more interested in, as i'm nearing getting my 502 fired up with the holley sniper, if I got a ignition system, would it talk with the efi.
I'm just running a bowtie hei dizzy up top my 502.

Correct. And it really does and wiring is clean plug and play. I went all chips in. You'll notice how refined an old school engine can be.
my truck idles 600RPM, I'm happy

The only bad I've heard is the occasional cutting out at random times, but that was from a old model I think.....
We shall see... My k5 isn't hitting the road much anyways.

With that full holley powered engine management, did you noticed a jump in power from the carb you once ran?
Or did I misunderstand

Actually, I think I did it wrong with new , first post... I thought that picture would be my profile picture but isn't... And I can't see how to change that now.
