Tunnel Ram on a 383

Been there done that and seen it many times. What is a mild cam in a 440 can be a bottom end killer in a 383. It is a different story to some degree if you add compression but the shorter stroke likes a bit of help down low. It is still going to wind like crazy because you have good heads. You did say street friendly. Now if you spend bucks on a converter or a 4 speed setup and low gears you can be more aggressive. But I did not interpret your post as being that type of build.
