383-440

[oldtinkerer]

any quick way to tell a 440 from a 383 just looking at the engine?

383 is stamped on pad on drivers side front of block in front of the head 440 is stamped under distributor
also width of intake manifold

I was always told to look at the top of the block, on the 440 there is a pad where they stamp different codes at the front near the driver side head. The 383 doesn't have this pad.

The RB engines, 413, 426 wedge and 440 will have this pad with the engine displacement stamped on it.

Plus they are wider and taller than the b motor (383). You can tell if you eyeball good enough.

B engines, 350, 361, 383 and 400 look like this. No pad near the distributor.

Just to confuse you a little more.... they did make a 383 RB block in 1959 and 1960 for the Chrysler Windsor and Saratoga, but they are very rare. I've never seen one, but they are out there.

The RB block is taller than a B and is why they are wider

Note the right side .. RB deck is taller note the rusty but non-greasy taller deck above water pump housing mating surface




RB separation above WP housing top mating surface

B deck surface flush with wp housing top mating surface

Not even under the hood at a show ?

Nope, can't say that I have.

I may have seen one and didn't realize that's what it was...

Late fifties Mopars are very rare around here. They didn't make it through the winters well and had a lot of rust issues, especially the 57 and 58s. Then the scrap prices have always been higher... so the survival rate was pretty low.

A fast, easy way to tell B from RB... As mentioned you have to look for number on the engine to tell if it's a 383 from a 400.
