The new motor has wide pulleys for 3/4 inch belts and I need to change to the narrow pulleys. Does anyone know what year car or truck that has a narrow crankshaft pulley that will fit my '52 235.

1953-54 has a 6" diameter pulley and should be used with the high mount water pump.
1955-62 has a 6.750" diameter pulley.

Is there another solution. Dale | | | | | Joined: Jan 2001 Posts: 5,337 'Bolter | | 'Bolter Joined: Jan 2001 Posts: 5,337 | 1955-62 truck balancers used a 1/2" belt. If you use one of these with a 3/8" belt the belt will run deeper in the groove and the belt will be running at about the right diameter. The pulley groove is plenty deep.
