I am curious about this. I have a cast crank 350 with cast pistons and a 2 bolt main block. The only bottom end modifications are a Z-28 style oil pump and ARP rod bolts. How high can this thing safely be revved? I have the limiter set at 6,000 RPM, but tend to shift it at 5500.
As a corollary to this, I am sort of mulling over the idea of a high RPM SBC for road racing right now. Not that I can afford to build it, but I wonder what I could do to build such a monster. I am thinking a 400 block with a 283 crank and spacer bearings, and 6.2+in rods. Add to it some lightweight pistons and a roller valvetrain and maybe dry sump oiling. Road racing is the idea with this one and low end torque would only need to be adequate, not exceptional as it would mainly be used from a rolling start and not for a standing quarter or eighth drag race.
