Ok I was wondering which harmonic damper spacer I need to run on my motor, it's a 1974 351w. I was told by a friend to run the .350" spacer, i just wanted a 2nd opinion though. Thanks guys.
Best bet is to call the manufacturer of the balancer.
I installed a Fluidamper, which needed a spacer for the pulley, and called them. They gave me the March part number. About 5 years back, so I cant remember the numbers.
well its a 4 cylinder, so i dont think im gonna be able to use any of the belt systems from it. I was think about getting a complete setup from March Pulley's. My dad owns a machine/fabrication shop, so machining stuff wont be a problem.
