It's probably a stock 258 cam. I can give you the specs if you can tell me which year was the engine it came from.

the 258 had several types of stock camshaft?
is there a 258 cam with "higher" specs then a stock 242 cam?
if so, is it a better cam for 4.6 carb'd stroker then a stock 242 one?
:roll:

Not really. The stock 258 cams are too "soft" for a 4.6 stroker. Sure you'll get bags of low rev grunt but there won't be much power above 4000rpm. Here's my cam spreadsheet:
