C1 bellhousing part number

[Paul Y.]

A friend of mine needs to know the casting number for his 60 vette bellhousing. I told him that one or more of you gurus would be able to tell me. Thanks in advance. Paul

Beings that this is a somewhat hard to find part, is there another bellhousing that would work even though not correct? Thanks in advance. Paul

Yes. GM casting #3733365 (cast iron) or GM #3779553 (aluminum).

Early cars had the cast 365. Mine is 1270 and has the cast. Not sure what Vin number they actually changed to alloy. Stewy

Also cast # 257 for a cast iron bell with the narrow clutch fork window.....

The '257' bellhousing was used for passenger cars only. Some of these may be drilled and tapped for a different clutch fork stud that will not be compatible with the Corvette clutch fork. I think that later ones are drilled and tapped for the same stud as Corvette, though. However, there may be other differences that would present a problem in a Corvette application.

Joe,

I just pulled that 257 housing from my 57 that was retrofitted with a 4speed when I originally purchased it. Din't mean to imply it was a vette bell but one that would fit and had the small window.

Interesting to learn of the differences.

Thanks
Joe
