Quote: I also noticed that the shafts are "hard chromed" which may indicate that they are comparable to what Mopar & Crane sell for their ductile iron and/or aluminum rockers. The regular Harland Sharp rockers are advertised as using "heat treated, heavy wall rocker shafts."
Good point I hadn't considered; the Mancini "budget" kits may not use the high-end HS shafts, which would be a downside for 500# open pressure usage.
