Need help Identifying this Carb

Carburetor is a Holley 6145, a later version of the 1945. Chrysler part #4179057:Holley #R9179 Date of manufacture March 1980. Carburetor probably came from a 1981 Dodge truck with 225 engine. It would be nice if you could replace it with the earlier Holley 1945.

Screw that. LOL I'd put a Carter BBS on there so quick, it's make your head spin. I caint STAND the Holleys in e slant. They give nothin but trouble, IMO. Even the early ones. Course the best thing would be a sooper six setup. JMO.

Lets get Dan's opinion on this.....even if he tells me I'm an idiot. I'm a big boy, I can take it. LOL

@slantsixdan a little direction here please? Is this the "correct" carburetor for a 75 slant six Duster with possible California emissions? I would thing it's for a later model, but that's why I'm askin your expertise here. Try not to kick my *** too bad. lol Thank you kindly.
