flywheel/starter size
I am converting my automatic 79 to a manual. Will a 10.5in clutch, flywheel (168 tooth), and bellhousing bolt up to the stock starter?

Re: flywheel/starter size (79corvette)
Flywheels with two different diameters are used on Chevrolet small-block V8, big-block V8, and V6/90° engines. Large flywheels are 14" in diameter, and have 168 teeth on the starter ring gear. Small diameter flywheels are 12-3/4" in diameter and have 153 teeth on the starter ring gear.
The difference in flywheel diameters requires two distinct starter housings. Starter noses used with large diameter flywheels have two offset bolt holes; starters for small flywheels have two bolt holes which are parallel to the back of the block. Most Chevrolet blocks are drilled for both types of starters. If you are changing the diameter of your Chevrolet's flywheel, you can convert your present starter to fit the new flywheel by installing the appropriate starter nose, starter motor housing, found within each engine classification.
