Demon Carbs ??

[Marvin S]

Okay I got a deal at the swap meet on a deamon, It looks about new. The guy said it came off a 383 car that he bought and he was installing a 440 and liked holleys better, so I ended up with it.So here comes the big question.Is there anyway to tell what size these things are. There are no numbers on it. It looks just like the road deamons in the summit Cat.It is Vac secondarys and elec choke.Primary bores are 1 9/16 and secondarys are 1 11/16. It sure would be nice if all the companys could stamp the size on em.Thanks

Most likely a 625. Mine is slightly spreadbore and has no numbers on it either (625 road demon). That guy liked Holleys better? Duh, this is a Holley with all the hop ups already done. Blended bowls, power valve protection, sight plugs, 4 corner idle, billet base plate, bigger bowls, better material. Good score, a few of us have them and they rock. The differences in the line up are interchangeable venturis, externally adjustable vacuum secondary, and annular boosters. I think alot of the parts are interchangeable on these carbs, so no distinctive marks are evident on different lineups. my street demon had annular primary and secondary boosters and was set up for gas. It had a long part number that could be decoded on their website I think.
