Chevrolet CMP Engine variants

[Bob Carriere]

If you use the harmonic balancer of the 216 ( it while fit the 235) and keep the 216 water pump pulley than you have the same speed.....however, I used an alternator ( sorry I sinned) so I had to change the pulley on the alternator to match the 5/8 belts requirements of the rest.

Note some 216 had large 7/8 pulleys.

what ever you do do not remove metal from the block..... I would be concerned with creating a weak area even if the later 261 had a huge hole to allow the pump to sit inside the block.

Let me follow with some basic photos.

First just to clear up the cab 13 versus cab 11/12

The first picture shows a cab 13 set up..... the rod is shorter and is connected to another straight rod that goes to the gas pedal.


PS...... just noticed that the second and third picture show evidence that the throttle shaft was grinded above the pulley to gain clearance...... shinny area.

*****(The second set of grey engine set up shows a cab 11/12 longer arm set up.) **** WRONG it show same cab 13 set up.
There is a flat stock piece of steel that fits behind the rod.......

I will follow up with my modified set up to gain clearance.
