Didn't mean to come down too hard, sorry. In my mind this is part of the fun of Mopars, the discovery of the "true facts". Where/when was the engine built, and those gurus who can look at a VIN and tell you what it probably came in, are cool.

Another fun thing is knowing which parts came on both a 2-barrel 383 and a 375 hp 440. I started out in the chevy world and it was a real bummer to hear that there were almost no parts in common between a 165 hp 350 and a 370 hp 350. Or even a garden variety 396 4-barrel and a 375 hp 396. Block, crank, heads, rods, pistons all different.

Good luck with your car!
