Ok, this makes me the biggest retard of the year but WTF???
Late last night, ALIENS landed in my backyard! They were very friendly, we had a few beers, talked telepathically for a couple of hours, then they got in their flying saucer and LEFT! Really! It actually happened! BUT...I DON'T HAVE ANY PICTURES!
You call MY pictures and information nonsense, but offer absolutely no proof of your own! Let's look at the indisputable FACTS of this post: The question was:
"Will a 318 A body mount fit on a 340?" FACT: You said "
yes if you shim it" Again look at the picture:
The mount on the right is a FACTORY "Mother Mopar" bona-fide 318 A body mount. It is what you will find if you are lucky enough to get an NOS one somewhere at an old dealership. It is what any factory parts manual will show you. It came on 99.999 percent of "non alien" 318 A bodies. THAT is a fact. If you can take THAT mount, shim it, and bolt it to a 340 engine...YOU ARE A MOPAR GOD!
The FACT is you can't. It's missing the ear to bolt on. It can't be done. If I gave you that mount YOU would have to admit that it can't be done. I said you are incorrect. THIS mount cannot be shimmed to work on a 340. The FACTS prove I'm right! This mount will NOT bolt to a 340! That's not nonsense.
So now YOUR answer is that "your mount didn't look like that".
So! You are saying that you had some RARE FACTORY EXCEPTION mount, but that I AM TALKING NONSENSE??? Your answer is "never say never?" Even if your fantasy mount is absolutely real, the fact is that I am still correct: A regular "run of the mill" 318 mount that most people asking the question are going to have on their motor will NOT bolt to a 340 with a shim. EVEN IF YOU HAD ONE THAT DID, it is incorrect to tell this guy that his mount is going to work, because the odds are that it will not. You are simply disseminating false information. That is a fact.
Again, I have spent WAY too much time on this subject, but I am developing a hypotheses to support YOUR claim. I really wish you had come up with the picture, because after one look, I could have verified my theory. While you CANNOT bolt a factory 318 A body mount to a 340, the inverse is NOT true...You can EASILY bolt a 340 A body mount to a 318! It is approximately 1/4 inch narrower, but with a shim it should bolt right on the block. The extra ear is just not used. Furthermore, if you DIDN'T shim the 340 mount, the torque on the bolts would "stretch" the 340 mount until it touched the ears, resulting in a wider 340 mount. Perhaps some tired line-worker on a Monday morning or a Friday afternoon did this because his bin was out of the correct part..I don't know. As the Mythbusters always say, it is plausable.
IF you got this car with the stretched mount and then tried to use that part on a 340..yes, it would easily work with a shim. I have given you a reasonable way out of this arguement. Can we PLEASE just tell the guy that most likely a shim won't work on his 318 mount???
