swaping a 318 for a 360. I want to make sure I use the correct left motor mount. Can any one post a picture and a part #. Does it have 3 bolts or four to mount it? Thanks for any help

Google and youll find it...also are you running headers or manifolds? I would think the 318 manifolds to be a bit restrictive

The replacement Spool motor mounts show the same part # for both 318 and 360 engines. They expect the user to use washers as spacers to fill the gaps.
Also, while the 360 manifolds may flow better than 318 units, the gain isn't much. Mopar Muscle magazine did a comparison on a crate 300 horse 360 several years ago. The difference was aroud 5 HP. The 340 manifolds added 7. Certainly NOT woth the extra coin to buy. If you already have them, then......
