Technical Clutch sizes for ‘63 Impala

Hey guys so I’m shopping around for a clutch for my ‘63 Impala . It’s currently a 3 speed and I’m going to be installing a 4 speed Muncie M20. This is just for a daily driver so what size clutch setup should I get? Any brand recommendations? SACHS?
Thanks

 

Do you know what size flywheel it has? and what size clutch it has now?

 

10&1/2"

 

Generally , you can't put anything bigger than a 10.5" in a passenger car bell housing , there are different bells & flywheels dilled for larger diameter clutches.

 

Centerforce is my clutch of choice. Had one In my 63 bel-air, 350, 11”, m20 Muncie, 2:73 rear gears with a 31” rear tire.

 

I run an 11 inch Zoom in my car. I use a cast iron 1955 Chevy bellhousing. For years I thought it was a truck piece until I ran the numbers. The truck ones are good too.

You'd have to run the truck starter that bolts to the bell.

With the smaller clutch, figure what you want to do with it. General cruising, going to the track, etc.

 

Just match up what’s all ready in it. The 4 speed will actually make it easier on it.
