Can't seem to find any custom grinds. I did however email crane cams and here is what they said,
We do make special camshafts. However, in these type of applications we would have to make a minimum of 3 sets of cams. Typically a finished camshafts will run between 2400 to 3000$ per set (Intake and exhaust camshaft). If their is any interest send me the camshafts so we can quote accurately and reverse engineer.

Check out he cost!
