Holley vac. secondary 4 bbl. identification
 
Came accross an old Chev. Holley vacumn secondary 4 bbl. in my garage. Looks like maybe a 780 CFM. I'm sure it has been there for 25-30+ yrs. and I have no idea what it came off of. Can anyone identify it?
GM #3884505-DA
List 3367

Looks like a single feed 585 cfm off a 327 66 vette.

66 327/300 or 350 hp Corvette, Nova, Chevelle or Pass car. Holley's sells them brand new for $550.00

I never even thought 585, but yes, I'm sure that's what it is. The 780 would have been a dual feed.
