Hi Larry, My 468 will spin past 7k rpm with a hydraulic roller, but then I built it with rpm in mind...
It has AFR heads (which flow very good), titanium valve spring retainers, double valve springs, extremely lightweight Schubeck hydraulic roller lifters (only 64 grams each), a Comp hyd roller cam - .612" & 245* dur @ .050", Jesel shaft rocker arms, shorter than stock push rods, lightweight Scat crank (60 lbs), lightweight pistons and rods, Victor Jr intake, and custom built headers. I also adjust the lifters with zero preload to prevent pump up when the rpm gets up there. It's a little noisy but still quieter than a solid cam.
