You question is a bit vague. Some will say a purple shaft.

I like old vintage cams, big and stinky but some dont.

There are from time to time some good old vintage cams on ebay, her is a current one for a BB and it almost looks to me like you could use a new oem spring or still a single, but im not a BB or cam expert but here is the link.

Pretty mild but above stock it seems.

You should probably post the combo you have now and what your expectations are.
