[QUOTE="52merc, post: 15891490, member: 197"] JE makes 5 pistons at 9.5:1 CR. PN 314629 is stock bore with a -6.6 cc dish. PN 314630 is a 0.010" overbore with a -7.0 cc dish. PM 314631 is a 0.020" overbore with a -7.3 cc dish. PN 314632 is a 0.070" overbore with a -9.0 cc dish. PN 314633 is a 0.149" overbore with a -11.8 cc dish. These CRs are calculated by JE using a 53 cc Chamber Volume, 3.543" Stroke, 5.933" Rod Length, 1.220" Compression Ht, 8.925" Deck Ht, and JE Head Gasket with 3.630" Diameter and 0.039" Compressed Ht. The .010" or 0.020" overbore are probably more in line with what you are looking for. Just letting you know what is available. I'm not making any recommendations here. [/QUOTE]
