I'm betting the priming rod is different for a small block Mopar, which I think would work with this 325, and I have a bb one.
Also, not sure if you need to turn the crank like a bb during priming.
I have one priming rod which, unless my memory is completely shot, I have used on both big and small blocks. No idea about turning the crank, not sure I've done that (maybe should have?).
