It surprises me that enterprising engine builders didn't take advantage of the 383's strengths. Skirted block, almost indestructible; shorter stroke than a 350 Chebby for high rpm operation; shaft rockers as std.
Most guys went right to the 440. The 383 was given a “Ehhhh” or a roll of the eyes. Followed by, “Why didn’t you do the 440?” Or some other comment in a disparaging manor.
