Anyhowzer, one of those things is the need for stronger rocker arms,
As I found out the spring combo they boasted likes to punch pushrods through the factory stampings that they swore could handle it .
So I'll be plunking down my hard earned for a set of Harland sharps .
Mopar Performance used to sell stamped replacement SB rockers that were supposedly thicker than stock. Had that same problem with spearing rockers using factory seasoned parts. Cam was a real mild flat tappet Crane with something like .450ish" lift. Set of those cured the problem, but I'd be damned if I could find the part number. This was 15 years ago.
