My 511 is 11.5:1, cam is a solid roller that has about .725/.700 net lift with 1.7 rocker arms. The heads were CNC ported from Hughes. It was a PITA to get the valvetrain geometry right at that lift due to a 2.00" installed height. It was way off and the rocker hit the retainer so Mike at b3 hooked me up. Immight have been the first guy here to use him come to think of it. Pistons are Diamond -12.5cc dish, hellfire rings. Oiling system consists of a Milodon road race pan and Milodon pump cover for external oiling. Other than that nothing really out of the ordinary. Blem PEP crank, Cordoba block, RPM rods with ARP2000's and a mile of side clearance and bcr aluminum caps.
