Were there even that many made though? And I don't think they kept it forged for very long into the 70s as the power went down.
So what rings should I look at? I'm guessing i'll have to file-fit them myself or do they come pre-gapped in different sizes? Is there a gap spec for factory Magnum pistons when adding light boost?
Also i'm guessing when I remove the crank to replace the bearings the rear main seal will be "disturbed" and i'll need to install a new one?
