DVW, what stroke and RPM are you running? Have you seen any advantages to a 9mm ring pack over a standard 1/16" 1/16" 3/32" ring pack? [/quote] 4.5" stroke, it runs 7000-7200. It had .043" ring pack previously. Not much difference that I see. Still have the 4.500" Wiseco pistons, flat top, big valve reliefs, .043"ring pack as well as the matched BME rods (7.150"x 2.200'x.990"). They are 426 forgings. Doug
