What can any of our esteemed cam experts tell me about this cam? From the cam doctor report: Intake- 276 duration & 106 lift CL ATDC @ .050, .287 peak cam lift/.450 peak valve lift Exhaust- 256 duration & 111 lift CL BTDC @ .050, .284 peak cam lift/.415 peak valve lift This seems to be a pretty radical cam so I'm wondering what its application might have been- blower, injected, boat, etc. Also, what RPM range would this cam be good for? I'm told to expect about a 1200 RPM idle with this cam. It is a very nice billet cam that appears to have been ground some time ago, but has no markings at all on it. I'm also wondering if the 331-390 Caddy siamesed center exhaust ports can benefit from any lobe changes on those affected cylinders?
