Looking for Info / Specs on Obsolete Mopar Piston

Use 2.67 grams per cc for this grade of silicon-aluminum alloy. That would be around -21.4 grams for the 8553PT's and -28.6 grams for the 1008's.

Your bobweight will change by the same amount as the material milled off of one piston. I would absolutely rebalance with the amount of weight removal above. I have no idea waht is meant by an 'overbalance' condition.....????

The 1008 and 8553PT are very similar but the 1008 is a more consistent compressed thickness.

OK on the cam... yeah, I suppose it is not worth the price. Someday, Ima gonna call Crane to see if they still have those old HE grinds around....
