    that aint that high these days

    Pro stock in NHRA turns there 500"BBC 11,000 plus at the stripe and a SB2 small block can easily handle 11,000 RPM for drag racing purposes.
    What he is saying is not an unrealistic rpm for a SBC with a killer expensive valve train and non stock rotating assembly pieces including the block.

    I am not an expert here, but in a garage-built SBC on a lower budget I would focus on the max HP via the best power-curve you can get while holding together. In other words, not so much emphasis on high RPM necessarily. Why so much focus on the RPM if the torque curve & the longevity will suffer?
