Waring, you assume all risk doing this mod. These are examples not directions to be followed.

Well after having this for some time I finally got around to installing the Jeff Bronco Graveyard mounts. They are high quality and well built, they come bare metal so you have to paint them before you install. Also you need to grease the bolt that goes through the urethane bushing, or you may get a squeak once you tighten them down the the motor moves. Here are some pictures. The new

Replaces the old, Driver side

Pass Side

I left the upper intake on and the exhaust was still hooked up when I did these, so it is a true driveway three hour fix with basic tools. The pass side front motor mount bolt takes forever to get out but I used a regular deep well socket on 1/2 drive to get undone, I think it is a 19mm bolt size. This one

Once I got the bolts loosened, just broke free, I jacked up the motor. Redneck way but works, warning put some additional support under the motor before putting your hands in there just in case.

.
To get the old mounts out I had to jack the motor all the way I could then wiggle them out. The new I attached to the motor first then slide the crossmember piece in afterwards, was really smooth getting the new in. As you can see in the last picture, I already have the new one in.
This mod has helped a huge deal with the motor moving during revving! It is a lot smoother, I would post a video of it but now my balancer is going out causing some wobble of the belt. Hope this helps, anyone on the fence of doing this.

Sweet! I was actually looking at those very same mounts. I'm irritated that I can't find a decent motor mount locally--just Chinese and indian made thin guage junk with poorly drilled mounting holes, and tabs that hit the block. I'm about to return my third set of junker mounts and buy the ones you posted. Thanks for the endorsement.

Think the 2x4 in the above pics has anything to do with this.:haha

I have been looking for some like that for the 460 but no avail. Maybe someone else knows? I rip my L&L ones anytime I hit woops or a mud bog. And its pissing me off. Maybe someone can point me in the right direction?

No sir, the 2x4 has nothing to do with a balancer going out. As long as you don't bang on it, they are good. This is the second set I have replaced using this method. The rubber inside the factory balancer is just working it's way out on me.

<<the 2x4 has nothing to do with a balancer going out.>>

That 2X4 might not be the culpret for your balancer woes, but I promise it ain't doing it any good! :shrug These 2 piece, elastomeric balancers are wimpy when subjected to excessive loads.

When you jack up 500 pounds on the end of the crankshaft, you run the risk of slightly warping the end of the crank, which is all it takes to throw off every balancer you ever mount and make your crankshaft bearings go out of round.

Another way to effectively jack up the engine without doing any damage is to put a 1/4" rubber buffer or a carpet remnant underneath the oil pan, followed by a small section of 2X6, and then jack that up.

Anyway, I ended up getting those mounts you recommended, and again, I appreciate your write-up. I'm looking forward to having them, because both of my mounts are trashed beyond recognition, and I'm not really interested in going down the same road again if I can help it.

Regards-

I highly recommend them. Also they make adjusting the motor easier. Mine made no change to engine height a couple Lightning guys said these made their motor sit 1/2" higher though.

+1 on the recommendation. Quite possibly the best money I've spent in a long time. These mounts are incredible. In fact, EVERYONE should go get them.
Per your mention of the engine sitting higher with the new mounts, mine does not either; well, it does, but only because I had to shim the mounts 3/16" to clear the oil pressure boss on the block.
