La 318 mount don't fit 5.9 magnum.

73 to 76 360 uses a different mount. Parts house I worked at has two different part numbers!!!! And crackedback you will notice I said 74 360 which is the newer style not the biscuit style you are referring to.

Which is NOT what he is working on for mounting the engine. I've got an 89 360 in a 70 Dart, so I use the spool style with a stock k frame... the engine has NOTHING to do with it. LOL. He has biscuit mounts, therefore you are still wrong no matter how you want to dance around it.

pick your parts, pay your money!

I'm out and another example of why many don't post much "help" in here anymore. Good day folks.
