were can i find a list to tell info on the 2 383 motors i have, like what they came out of and if one is # matching from a 1968 charger
You would have to know the V.I.N. of the Charger it came out of and if it was stamped on it it would be at the back of the block near the mating surface of the trans/engine at the top near the oil sending unit. Not all `68's were V.I.N. stamped and then the casting date comes into play.
