To me this is the best cam hands down for a mildly built BBB. My Lunati I had was almost identical to this one. Mine had slightly less lift. Still have all the torque, but it would wrap out to 6k or more with ease. All with 2 plane intake and ported manifolds.
That is fantastic news! What are the plans? Personally, if the motor is healthy I would put in a cam suited for stock motors, get some better rockers and adjustable push rods, maybe some headers, Edelbrock B4B intake, and try to score a '71 455 Q Jet. Oh, and a good distributor.
The guy I bought it from said the motor had a slight knock and he swapped it out for a customer who wanted a 455 in his GS. He seemed to very honest and based on the casting #s the motor is just what he said it was. Except for the rebuilt your suggestions are very close to what I had planned to do with it.
