Hello,
I have a set of 360 mag pistons, 7 from engine and 1 from another engine. One was damaged and I bought a used piston/rod on ebay.
So I have gone through and weighed them on the work scales. (counting scales) and these are the weights in grams.
1354
1352
1353
1359
1350 - This is the piston from ebay
1350
1350
1354
So we have a 9 gram weight difference, I have no idea what the factory weight tolerance are for a 360 mag, I would suspect that I should be able to bolt up with my 1350 replacement piston/rod as its not way different.
I do understand that everything should be the same, but in the factory real world its not. After market probably get to .5 gram difference. I know that balancing is quite an art. Weighing rods, pins, rod ends etc.
Thanks
Bruce
