My 427 C.O. .015 over consistantly turns north of 6000 RPM. However, unless you build your engine right I would advise against pushing that 7000 RPM window. I did at Texas Motor Speedway about 6 years ago and it scattered bits all down the front straight away, starting at the end of turn 4. Now, saying that I will say that particular engine that let go had a legitimate 4000 race miles on at the time it let go. I believe I got my moneys worth out of that build. I sleeved the block and sold it to a guy in Austrailia for $600. Most of the rest of the engine is on my current build (heads, roller rocker arms, intake, carb, MSD Dist. etc). Crank, cam, one rod and 7 pistons, and all the valves and push rods were trashed
