If you are talking about a Chevy 350 c.i. engine, it is considered a short stroke engine designed for medium to high RPM. My 1957 283 is governed at 4000 RPM, it was able to sustain that for hours and/or miles. The 265/283 is the grandaddy of the 350, same basic engine. A 350 that is in decent condition will have no issue with that engine speed.
