Distributor Identification?

[Mark A.]

I HAVE A DISTRIBUTOR THAT I CANNOT FIND OUT WHAT IT CAME OFF OF. I REMOVED IT FROM A 57 CHEVY BEL-AIRE. IT IS A TACH DRIVE, DUAL POINT UNIT. IT IS MADE BY MALLORY. THE ID PLATE SAYS PART # YC-465-HP. CAST INTO THE SHAFT HOUSING IS THE NUMBER T310 C 465. DOES ANYONE HAVE AN IDEA WHAT THIS DISTRIBUTOR WAS FOR? DID ANY OTHER GM VEHICLES USE TACH DRIVE DISTRIBUTORS OTHER THAN THE CORVETTE?

Re: Distributor Identification?

It was designed to be used on any Chevrolet that needed a mechanical tach drive

I'd say it's just an old aftermarket-type tach drive distributor. The only Chevrolet model that I know of that used a tach drive-type distributor was Corvette. However, it's possible that those few passenger cars in the mid-50's that were equipped with FI also used a mechanical tach. I doubt it, but it's possible.

Being an aftermarket-type piece, I doubt very much that it was designed for a very specific application (like Delco-Remy distributors used on GM vehicles). It's more "generic" but, since it has tach drive, probably mostly intended for Corvettes.

Also, mechanical tachs were used as an aftermarket-type retrofit piece for all sorts of cars in the 50's and 60's. So, this distributor could also have been used for that sort of application.

YC-465-HP is for small & big block Corvette w/ tach drive. This a mechanical advance dual point "double-life" distributor. Fairly rare.

Take a look at some of the old Mallory catalog pages posted on this link -

...and it appears that the "YC" designated Corvette on one of the pages, and also the "465" is used on the 68 Corvette dist. designation.
