Ya a 383 is a 350 block, cylinders bored to 4.030" with a 3.76" stroke. If the crank wasn't replaced, you don't have a 383. You can have a number of different rod lengths. Ther is no reason a 383 balanced and blueprinted with forged rotating assembly cannot live in the higher rpm range with doubled valve springs.
Crank is an Eagle 3.75 inch Stroke. I've driven this engine for about 200 miles and so far so good. Has plenty of power, so much that it's hard to drive on a wet road-- Terry
Sure, spin that mild cam that stops making power around 5500 to 7000. It'll do it for awhile, there's just no reason to do so. It's pointless. More noise, no more power, and excess wear.

If the cam's mild, it won't rev to 7, period. Doesn't need to, either. Good street V8's will outrun just about anything before they hit 5 grand, and the 383 will do it just that much faster.
