Red Ram Hemi.......

Cool!

Dodge 241's were made in 1953 and 1954. The number you're looking for to identify it is stamped on the block rail in front of the intake valley cover, between the valley cover and the timing cover.

Numbers on the Dodge hemi's start with codes like this. The 241 numbers really didn't change 53 to 54. These aren't all of the codes, there are more out there, just the ones I know and what they relate to.

There were other codes depending on what the engine came out of. I included the Dodge "poly" numbers because its not unusual for hemi heads to be found on a "poly" block, the only difference between the hemi and poly engines are the heads and pistons, the block is the same.

Here's a picture of the number you're looking for. You can see the valley pan, timing cover, and oil breather tube to figure out where you're looking. But yeah, no removal of anything needed to look at this number. The first one is a Plymouth 260 (which is basically a Dodge 270 block), the second is a Dodge 270 hemi.
