What the hell does that mean?
383
i got a 383 with a TCI TH350 tranny on a trade the other day.. The 383 had a broken crank twords the back of motor. looked like it was cracked before and finally broke. i was told it was pry from bumping the tranny and went into a lower gear and snapped it. Anyway its got stock heads and nothing fancy inside. Its got 1-5 roller rockers and not to sure about the cam.Im looking to get some power out of this. Any good suggestions on heads and crank? Money is somewhat of any option but i want this bitch to scream but still run pump gas.

Can't tell you anything about the castings on the cam.
CWC makes the raw castings for the various cam core companies, such as Camshaft Machine Company or Engine Power Components. Then they sell the cores to Comp Cams, Lunati, Isky, Crower, etc. So CWC could be anyone's cam with any specs from a factory replacment to a performance grind.
You could just measure the cam lobes with a micrometer, multiply by 1.5 and subtract .050. That would at least give you the lift figures.
