I'm a new owner of a 65 Plymouth Satellite with a 528 Hemi. I'm trying to learn all I can about the Hemi. I was told by the previous owner I have an "Indy Hemi" but I believe I have a Mopar Performance Hemi. I've been reading about these MP Hemi's regarding all the different blocks they came with especially the Cummins block which has not gotten very good reviews to say the least. How can I tell for sure what type of block I have? I DO NOT have the extra frost plugs in the block on either side of the water pump so I think that rules out the "World Block"? This engine was installed in the Satellite about 8+ years ago so if it is a Cummins Block it probably wouldn't have lasted this long.

Here are the casting numbers on the engine: 2468330-M, to the right of this casting is 17 A 1
2

On the front pad I have: 528, G081, 169X, PT

Any and all help is very much appreciated.

Thanks
Stu.
