I had made a temporary fix for the weak factory motor mounts in my 393 project car by making a bracket to mount to the left cylinder head, and connecting a chain from it to a clevis mounted to the K-member. This is what everyone did with big engines in my younger days. It worked ok as a temporary fix by allowing some movement of the engine, but when you hit WOT, the chain would hold it. I decided it was time to do a real fix for it. After researching what is available, it was a choice between rubber ones in stock type holders from MN12Performance, or the Polyurethane filled billet aluminum ones from MN12Technologies. The rubber ones are a improvement over stock to handle more power, but did not add to the rigidness of the front of the car, by making the engine act as part of the unibody like the ones from MN12Technologies would if I used 2 of them.

I ordered 2 of the mounts from Chad at MN12Technologies, and 3 days latter they were delivered. These are TOP quality pieces as advertised. It was a lot easier on mine than on most, since I do not have a lot of stuff in the way to make it hard. It took me 2 hours to replace both of them with not a single problem.

Here is a few pictures of the install.

Here is where I ordered them from.

I was going to post this in the 5.0 section, but the same mounts are used on the 4.6 also.

It's a shame that they do not make K-members :)

I took the Bird out to move the fluids around, and warm them up a little today. The new motor mounts worked out great. Even with me replacing both of them, it felt just fine. I have Flaming River steering shafts and joints, with no rag joint, and can feel just a little through the steering wheel at low rpms, under load. These are very nice mounts. I don't think that I would of felt any thing from the engine if I had a rag joint, since it it so slight.

By putting in the new mounts did it actually raise the hight of your engine? From the side by side pictures the MN12Tech mounts look taller, or once they are installed with the engine bolted down do they compress??? Just wondering because they look like something I could do right now while I got the tranny out of the car.

I think they look taller, since they are a little smaller in diameter, but are the same height. Top notch product.

My mounts are made to the exact height of the OEM mounts - it's possible his rubber mounts could have been a little collapsed.

I wrote him last night, hope he still might have one or two available. If that doesn't pan out anyone have another suggestion other than solid rubber?

Also a bit off topic, but do any other Ford platform suspension/subframe bushings cross with MN12's? I am looking at the possibility of aluminum subframe bushings, and also TPR/TRP (sp?) with xerg fittings to replace the poly bushings that drive me nuts with the squeeking.
