I know this has been covered, but a search didn't turn up what I wanted.  Any one have the specs on the 245 HP 57 cam?

Thanks

The '57 312 245 HP cam (B7A-6250-B), which is the same as the 270 HP dual quad standard cam, has lobe lift of .272" Intake (approx..400" valve lift with 1.54 rockers) and .285" Exhaust (approx. .420" valve lift with 1.54 rockers). The advertised duration is 256 degrees.
  The optional 270 HP cam (dual quad) is # B7A-6250-C. Lobe lift is .290" Intake and Exhaust (.447" valve lift with 1.54 rockers). Advertised duration is 290 degrees Intake and Exhaust. HP is 285.

This is a very old recently revived thread on the "285 HP" cam. Much confusion. A noted restoration guy told me from what he'd seen it was only a dealer option, but even that was very vague in his opinion and documented info. Good reading though.
