Piston identification

« **on:** January 27, 2008, 06:08:02 PM »

I need to know what kind of pistons I have, to sell them. They are out of an Olds 455 and have the numbers 1630 then under that is o2. I assume that means that the engine is bored .020, but the best I could come up with for the pistons was http://www.jegs.com/webapp/wcs/stores/servlet/product_10001_10002_910825_-1
Is that correct, or does anyone have any ideas?

Well now that i looked not all are in the center

Can't see quite enough but they look like Cast 8.25 to 1 (deep dish) .040 over ,another shot of the pin boss(inside the lower end ) would help Tom

A shot just a little bit further away so that the back of the piston comes out real clear. Those pistons have the same dish that the pistons have in the engine that I am selling on eBay and elsewhere.
