Tom, My Rambler 6 is a 258 bored .060 over with Federal Mogul pistons. The pistons are a full 360 degree dish and were supposedly for a 232 but came highly polished with the full dish, not like other 232 pistons I have had. They also sit .090 down in the bore. Am using a comp cam 260H with Clifford springs, retainers and roller rockers. Using an Offy intake, modified exh manifold to position outlet straight out. Turbo is from a late seventies carbureated buick v6. Using a edelbrock 500 cfm carb. Trans is a jeep turbo 400 converted to standard tailshaft. Car is a 1927 ford t bucket. Weight is about 1500 pounds. Sort of a retro rat rod. A pretty basic low buck set-up [img][/img] .
