I am building a 68 327 60 over. I have KB157 pistons, here is the link to the specs of them http://kb-silvolite.com/performance....etails&P_id=45

The cam i want to use is a comp magnum hydraulic roller and i either want the cam with .560lift 289 dur or 600 lift 314 dur. just dont want the pistons to smack the valves ya know? im using a single plane vic jr, and a custom built carb from pro systems. Some iron eagle heads are also topping it off. 64cc, 202/160 valves, and 200 runners. im working on getting 500 plus hp. It doesnt have a body yet but it will have 410 gears and a 3500 stall.
Thank you all,
Mike.
