Gen V 502 Piston Question
 
Can anyone tell me what the dome volume on a 92' Gen V 502 stock piston is? Looking up anything aftermarket and some list 17cc, seems way to high. Need this information to make sure I get my compression ratio correct.

The google machine has failed me, help!

Thanks!!!

this is the stock JE 700 spec found on line

The dome volume is +4 cc, minus a -3 cc valve relief, yielding a net crown volume of +1 cc.

Hmmm....now I'm really confused....according to my measurements that would yield 8.63 compression.... I know the heads and block are both machined .005 by me, but I am not sure about anything prior to me. I'm getting 120cc on the heads for CC, .011" for deck clearance, .043" for compressed gasket.

Dome volume is really the only other variable, since I know the stock CR was 8.75, it's gotta be higher than that...
