A few years ago when I built my 302 I bought speed pro forged pistons from Jeg's. At the time, they only had 1 set in their catalog for a 302, now they have 3. I'm about to redo the top end of my engine, and I need to know some things about the pistons so I know how much to deck the heads, how much valve lift I can have, etc. I was going to call speed pro and ask them this stuff but without a part number I can't do that.
What is the easiest way to figure all this out? Is there a part number on the pistons? I wasn't going to take the short block apart but I can if I need to. Or would it be easier to bust out the graduated cylinders and modeling clay and just measure it all? I haven't done that before and I don't own a graduated cylinder but I could probably get access to one. What would you do?
*edit*
I already tried calling Jeg's, their records don't go back that far.
*edit again*
Looking at my catalog, I think I might have it narrowed down to PN L248230F, which gives me 9.09:1 compression with 63cc chamber. What do I need to measure to verify this? And what size chamber do I need for 10:1 compression?
