Mine is the original 283 V8 with a governor that incorporates the ignition distributor and the carbuerator. The distributor has a flyweight/spring actuated valve that allows vacuum to control a carb. mounted diaphram. The shop manual calls for approximatly 4000 RPM as the governed engine speed. I was lucky with the shoes on mine, all have lots of meat - I had to clean and bake one rear shoe to get the oil out of it and it works without grabbing. The rebuild kits are available from Raybestos, you will need the casting number from each wheel cylinder to obtain the correct kit. Don't assume that all of the wheel cylinders will be the same casting #. Wheel bearing seals are also available as are the rubber brake hoses. I would like to add an overdrive auxiliary trans so I don't hold up traffic on the local 55 MPH two-lane but for now I stay on the gravel roads or the blacktop on Sunday mornings to keep away from fast traffic.
so essentially disconnecting that vacuum governor would turn it off? or replacing the distributor and carb with units that do not have those features?
