Help! Does position matter on externally balanced flexplate?
I bought Grandsportc3's AR 383 motor. He had a Tremek. I have a 2004r, so I had to buy a flexplate for the externally balanced 400 crank. Does it matter how it is positioned on the crank? Looks like the bolt holes match up no matter how I turn it.

I had my externally balanced motor balanced with the flywheel and harmonic balancer. When I ground a few thou off the shoulders of my rods to clear the cam I was thinkinig I might need to get the the motor re-balanced.
Not sure about your motor but on my notor if I changed flywheels I would have to get the whole motor re-balanced and especially if I went to a flexplate for an automatic.
