[Luis R.]

I have a doubt is about the diameter of the clutch in Corvette 1965 396, I read that use 10.5 some people say
that is 11.0. What is the correct diameter?

All 65 Corvettes used a 10.5" clutch regardless of engine.

10.5" unless it has been changed to 11" at some point in time.

10.5" unless it has been changed to 11" at some point in time.

In order to change to an 11" clutch the flywheel and bellhousing would also have to be changed. If the bellhousing is a GM #3840383 or 3858403, then it's a 10-1/2" clutch as it should be. If the bellhousing is a GM #3872444 or 3899621, then it's an 11" clutch and the bellhousing, clutch and flywheel are not original to the car.

As has been mentioned, NO 1965 Corvette ever originally used an 11" clutch.
