Hey fellas, I picked up this old breakerless Mallory distributor. I’m curious as to what it is and how old it is. Was this originally breakerless or is this a conversion? The number on it is similar to the old ZC/YC flat top dual point distributors I’ve had except this has a “P” after the ZC. I’ve done searches on that number and don’t see much at all that can tell me anything. Is this even worth messing with? Sent from my iPhone using H.A.M.B.
since the tag says IR in big letters, it's likely that it's an infrared breakerless distributor. but that's just a wild ass guess.
Squirrel- I think you're correct-a friend of mine ran one in his Boss Mustang and it resembled the one in the pic.. Doug Schriener
Well shit, Squirrel! I didn’t even notice the big IR in the background! [emoji16] Sent from my iPhone using H.A.M.B.
Hey Squirrel,,,,,wag is an engineering term I always heard . But Swag was the best engineering term I ever heard . It was a Scientific Wild Ass Guess,,,,,used by some experts in the aeronautics field . I always chuckled when I heard that ,,,,,,LoL Tommy
So how old is this thing? I can’t seem to find that number in any of the Mallory lists. Should I throw it in a box and forget about it? Sent from my iPhone using H.A.M.B.
ZC means it has both mechanical and vacuum advance. The 310 number says it fits small and big block Chevy, but not 348/409.
Thanks Fordors. Yeah, I got that part. I have a couple of older dual point ZC and YC 310HP distributors with the flat caps. I’m curious about the ZCP and what that means. I can’t seem to find ZCP-310HP listed anywhere. I’m trying to figure out when this was made, whether I can still get parts for it or if it is even worth messing with at all.

1970s is my guess, but that is just another wild ass guess. A picture or two of the insides might help....
From above, it looks like the IR distributor was part of a capacitor discharge system. You might have only the distributor part.
Hey! Thank you, gents! That’s the kind of info I was looking for. Now I least I have an idea of what I have. I appreciate your help. It does sound like it’s part of a capacitor discharge system, so yeah, I’m missing stuff. Too bad because it’s real clean and tight inside and the vacuum advance piston isn’t froze or anything. Thanks again! Sent from my iPad using H.A.M.B.
The '70s (later '70s) was when I bought my first Unilite. it had the goofy looking vac advance port like that one if that is any help.
