I'm toying with the idea, of treating my 409, to a Solid Roller Cam, for summer. I've read about the problems, of the lifters not getting enough oil at idle. Isky has Red Zone lifters. Is that a solution? I'm not looking for a .600 lift cam, and not planning, on going over 6000 RPM. Also, I can't see driving more than 300-400 miles in the Summer month's. How many of you guys, run Solid Roller Cam's, on the street? Can they live? Good idea or not? Thanks in advance.
