Re: What does this pulley fit?

From an ebay ad for the same part number...........................

1963-74 Corvette's with power steering. This pulley is correct for most 1963-74 Corvette's with power steering including 67 (427) w/spec/h/perf, 67-68 (327) w/spec/h/perf & AC, 69-71 (350) w/h/perf & AC as well as many other Corvette's. May also work in various other GM models from these years including some Camaro's and Chevelle's. Please check your specific application before buying.

Well, he's got some things right and some things wrong. It was never used on any big block. Also, I don't think it was used on small blocks after 1970 but I'm away from my references so I'm going just from memory. It was not used on any SHP small blocks except, maybe, those with C-60.

Joe,

It is listed in the parts book for 1977 as fitting a 67 427 SHP with PS. I'm with you as I don't think it was ever used on any BB. It does mate with a 3858533 crankshaft double pulley when PS is added to a small block midyear! Part is still available from GM.

I don't think it will mate with the 3858533. The 3858533 is a deep groove pulley and I don't think it works with this add-on pulley.

No way could it work with the 67 BB SHP pulley; that pulley was a cast iron pulley and accepts no add-ons, at all.

Thanks for all your input!

Re: What does this pulley fit?

According to my research the 3751232 was used on 1963-1972 Corvettes (and other Chev. models) with the N40 option.
Refer to the 1963 AIM (UPC N40, sheet 2.00), the 1970 AIM (UPC N40, sheet A2), and all the other AIM's in between. I believe that I have at least 6 or 7 of these pulleys in my collection.
