I am trying to determine which carb is factory correct for my 64 Lark R2 (serial 16472). Right now it has a non stude carb in place so I am looking to acquire and install the correct numbers matching carb for this car.

I checked Bob Johnstone's web site and someone wrote the following:

3507s - All R2 Avantis
3588s - 1963 R2 Larks and Hawks
3725s - Late 1964 R2 Larks and Hawks

(Seems to be a gap in the info above in that I don't see a carb for the early 64s).

So, which carb number would be factory correct for my car?

Any help would be appreciated. Thanks.

Early '64 used 3588s from '63.

The Jet Thrust Section of the '59-'64 Studebaker Chassis Parts Catalog shows only the 1561641 3725S AFB for all '64's both Lark & Hawk, I don't see how there could be a late '64, because the production run was only about 5 months, way too short for that.

I don't think it would matter. No one is going to look at the Carb. number anyway, as long as it is a sealed Carb. with the pressurized nameplate, any properly modified AFB will do fine, since they are made of unobtainium! [:0]

Tim,

How do you know that carb was also used in 64? Does your 64 have the 3588? Thanks.

I have checked A) the '59-'64 Chassis Parts Manual, B) the Avanti Parts Manual, July 1962 ed. and C) the Avanti Parts Manual, December 1963 ed.
the 3507S only applies to the early Avanti R2.
the 3588S applies to the '63 Avanti R2 and all Lark/Hawk R2's
The 3725S applies to the '64 Avanti R2 and all Lark/Hawk R2's
I have also cross referenced the above with the 1963 Master Parts Book (Engine) and the 1964 Master Parts Book (Engine). The '64 book lists the 3588S carb as Cancelled.
While it is possible that some early '64 R2's might have had the 3588S, The correct carb is the 3725S.
As Rich points out, there isn't an "early or "late" '64. Proudction ended before the '64 calender year ever started.

I had to 'build' my '64 engine because it was gone. The 3588 was all I could find in 2 years of looking. I've heard from several people more knowledgeable than me that it took some time to go through left over '63 stock before they started using the '64 spec stuff.
