hi. welcome aboard.
depending on what you're looking to find out, that pad will tell you at least a couple of things. yes, it is indeed a 440.
the block casting numbers I think would tell you a little more.
I googled a bit and managed to find this:
(I hope it helps)
what are you hoping to find out?
CJ
B/RB Mopar Blocks (stock)
Block Serial Number Stampings
(On B engines, 351-400 ci, there is a pad on the right front of the engine below the distributor. On RB engines, 413-440 ci, there is a pad on the left front of the engine. These pads contain stampings that will quickly identify an engine and usually tell you a little about it.)The stampings on the top of the block will look something like this:
C H 426 B
8-3-32
(These particular markings are of the form
Series / Hemispherical / CID / Bodytype
Month-Day-The Number Engine Built This Day | These marking are noted below. The stamping on the bottom of the block will be the formal serial number for that block and read similar to the following:
9-10-68 PT38326010001. These numbers are decoded as follows:
A. The first numbers are the date of the stamping (9-10-68)
B. The next letters indicate the engine assembly plant- in the case of our example, Trenton.
C. The next three digits indicate cubic inch displacement: 383 cid.
D. The next four digits (2601) are the 10,000 day calendar numbers: 2601 = Sept 10, 1968.
E. The final four numbers (0001) show that this was the first engine assembled that day.
