Carbed Magnum parts list?

yes .. you can put the V-belt set up (crank pulley, water pump pulley) on the Mag. maybe when using the Mag damper, you have to rework/slot one of the bolt holes on the crank pulley a bit

a Mag can be disguised to look like an LA Motor.

about the size - sorry - but best is to measure by yourself with a string to get the correct length
