I just bought the first Mopar in my life. Worked on plenty of them over the years but, never owned one. Anyway what I got is a 1970 W 500 2 ton truck with a 318 in it. The ID tag calls it a 318-3. I've done some research and understand that the -2 or -3 in my case is supposed to indicate a higher level of internal engine quality vs. a stock 318 in say a Dart or something. Any Mopar experts on the forum that can confirm this? And if so, any details as to what's better?[S
