The Best And Worst Years For Chrysler's Mopar 440ci V8 Engine

I don't know why but I had several late 440s blocks that did not need an overbore. Why? Maybe just luck and were not as woreout? I admit I always preferred a good 383 with a stick and 3:55 gears to a 440 with AT and 3:23/ But I am no racer.
I would not trade a good 383 for 5 340s/ Call me crazy!!!!
