Hi all. I'm not sure if this is the correct forum for this question, but I'm hoping one of you corvette gurus will be able to help me. I'm having clutch compatibility problems in one of my project cars. It has a 350 mated to a muncie using an 11" clutch and a 168 tooth flywheel with a make-shift hydraulic linkage. The clutch pedal is terribly stiff and I wanted to upgrade to something that would be easier on my hip. I found an 84-88 corvette bellhousing with the hydraulic slave cylinder and thought this would work fine. My problems is the bellhousing won't fit over the 11" clutch. This is where my memory is failing--do I need to get a 153 tooth flywheel and smaller clutch or find a 168 tooth flywheel tapped for a smaller clutch? Or is there some flywheel/clutch combination that is specific to this bellhousing? All I have is 168 tooth flywheels tapped for 11" clutches so I don't have anything to compare. I'd like to get this resolved before I spend the big bucks for the clutch fork. Any ideas? Thanks.

The 84-88 Corvette bellhousing can be identified by casting no 14048867. It is intended to be used with a 153 tooth flywheel, and that would limit the clutch size to 10-1/2".

There is no shortage of bellhousings made for a 168 tooth flywheel, but most of them originally used mechanical linkage. If you could be more specific about the details of your "make-shift hydraulic linkage", this might help to come up with a way to use one of those bellhousings. For example, do you presently have a bracket for mounting the slave, or are you able to make one? If not, a bracket may be available from outfits like Advance Adapters which cater to those doing Jeep conversions

A few 168 tooth bellhousings were made to be used with an external slave, but most of those have possible drawbacks for your present application, assuming I knew what your application was, which I don't. For example, 15530202 is for an 85-86 truck with hydraulic linkage, but the center hole is too large for your trans and you would have to use a spacer ring. Fortunately, the ring is available from Advance Adapters and others.

My 60 truck has factory hydraulic linkage and the right size center hole, but the slave mounts on the passenger side. Also the bellhousing is made of cast iron, which I like, but which you may think is too heavy.

Since you are willing to buy a bellhousing and you already have a flywheel and clutch, I think it would be worthwhile to work out a way to use the parts you already have by buying the right bellhousing.
