Reply to "What RPM are most of you turning with the modded engines"

On the upper limits of RPM. When I built my first motor I talked to jags of drag racers. One in particular who ran a 460 in a Opel was great talking to a kid who was interested in a pro street car. But he told me the weak link in the Cleveland were there cylinder walls. Any overbore in a Cleveland will result in too thin a wall to survive high RPM sustainability.
As I have learned from here. The bottom end is important too. But for a drag racer that doesnt seem to be as important.
But without other mods I too agree that you need to stay under 7000 RPM to ensure your engine will live a long and prosperous life!!!
