65 L79 water pump pulley

[William S.]

Can someone help me identify this water pump pulley off my 65 L79?

It is double groved and has part number 379x356. Cannot read the x number. It is 7 1/8 in diameter.





According to the judging guide, the underside of the correct pulley should reflect the area between the belt grooves. This pulley is smooth on the underside.

I believe the correct part number for the L79 is a 3770245? Can someone verify this?

Thanks for your input.

William -- the number stamped on yours is 3790356, and the '65 P&A catalog says '63-5 Corvette (exc. Sp. H.Per., F.I., C.A.C.). Plus for a ton of passenger cars and light trucks.

The 1970 version of that catalog shows 3790356 as '63-5 [same as above] as well as '66 Corvette w/A.I.R. (327) (exc. C.A.C., Sp.H/Per.). Also shows diameter as 7_3/23 O.D., which is close to your measurement.

Yes, the '245' is correct for '65 L79, except C.A.C.

At the expensive of asking a stupid question, what does C.A.C. stand for?
