Easy visual ID 383 vs. 440?

[goldfish65]

Is there a difference visually between a 383 and a 440....something easy to see even in a photo? For example, I'll see a '68 Chrysler on ebay but the decription doesn't say which engine it has. Thanks FABO gurus!

I always look to see where the i.d. tag is. The low decks have it in front and below the dist. The high decks have it front and center of the intake valley pan. Hope that makes sense. Sorry I don't have any pics.

BTW: the vast majority of 383's in big Chrysler's were 2 barrel engines where-as all 440's were 4 barrel's.

If it's got this cast in pad it's a 440.
