Large Lift ?
I will be getting a cam soon and was wondering how much lift the stock rocker arms can handle. Also i was wondering if Proform's roller rocker's sucked as bad as everyone says they do

I'm sure the rockerarms themselves can handle quite a bit. At least .550 to .600. The springs.... wont. Proforms look identical to Harland Sharp rockers which is what I have. Mine have been fine for the last two years at .510 lift. I'd get the Harlands for a few bucks more.
