Locking Engine Mounts

[chilort]

Well, I did it again. I broke both engine mounts in the truck and ran the fan into the radiator. Again.

It should go without saying that I am tired of this. So, I've got a couple of torque straps for a B-body from Schumacher Creative Services that I am going to install. I am going to do one on the driver side front (intended location) and one at the rear of the engine on the passenger side (hopefully to act as a mid-plate). I'm going to have to get creative to get the driver side front one in, but the rear doesn't seem too bad.

I'm also looking at getting some locking engine mounts. Neither Schumacher nor MIty Mounts carries a locking engine mount for our trucks. I finally contacted Johnny at Poly Bushings who does a lot of work with the 2.2/2.5L turbo Mopars. Luckily, he also works with a few other things.

He has a /6 mount that is thicker than the truck mount but that is a locking mount and has the studs in all the right sizes and all the right places (Indian made truck unit on the right and USA Poly Bushings locking mount on the left):

Thoughts? Will the extra height raise the engine too much?

It only looks like 1/4 inch or so of difference. Your running a big block or small block? Only thing with a small block might be distributor clearance on the firewall might be tight. They may be a pain to get in there, you know aligning them up and all. Might as well try it then you will know for sure!

Do you have a huge cam or something? I don't see how you keep breaking them either. Sounds like it might be an engine balancing issue. How about more engine specs.

looks to be a BB...maybe 383????

440 (only 9.2:1 compression), Eddy heads, Eddy Performer RPM intake, 750 Holley, 3.23:1 gears, Lunati 60303 cam, Turbo Action 10" converter, 727 built to shift hard, long tube headers, full 2.5" dual exhaust. I break mounts when I get traction; most of the time I don't get traction.

The difference between the stock mount and the Poly Bushings mount is 3/8"

doesn't sound like you have much choice.

And it runs very well. Jeremy gave me a very nice ride when I met him. I thought I saw a recent Schumacher ad with locking motor mounts. I didn't pay much attention to what they fit so maybe they won't work for us. I broke a couple mounts in my '64 330 after the 440 install. I made an angle iron strap to hold the drivers side front down and never had trouble after that.

I thought Schumacher was going to make them too. Must be the bad economy.

That's the mount for a newer truck and it is made by Schumacer Creative Services (http://www.engine-swaps.com/Pages/Produ ... html#head2).

So you were able to use those without a problem? They look to be thicker than the stock mount too. I do like how the internals are constructed. Looks like it would be difficult for me to break.

[RussRoth]

I just saw a Schumacher ad again and they were showing locking mounts but did not list them for a pickup. I thought most BB mounts were the same but maybe not.

[plydus340]

its been so long since i did my motor swap, i believe this is the mount i used. i bought everything from mancini. they are a biscuit mount, and thats what im using.

[chilort]

The location of the center stud is different on the '72 and up. Though, I don't know if that would make a lick of difference in this situation.

Well, if breaking stock motor mounts is an issue then maybe I'm better off building my own strut style mounts with urethane bushings...I don't have the stock big block upper mount brackets anyway, and they seem to go for $50, so I guess I'm better off building better ones myself...good luck with the locking mounts, and that's a damned nice 440 you've got there...

The sandwich style leaves much to be desired when it comes to keeping a high torque engine in place. There's a reason drag cars use motor plates.

[Ruiner]

This is why the 413 in my drag car is solid mounted...I hate biscuit or block rubber mounts, all I need are the dimensions from the engine mount holes to the flat part of the upper mount and I'll fab my own setup with 3 round captive urethane bushings per side and I'm good to go...I'm not really a fan of relying on stock designed parts, especially when the replacement over the counter pieces are typically cheap quality import stuff these days...

Awe, come on! You don't like having your choice of India or China?

Seriously though, at least if you buy something from Johnny at Poly Bushings or one of the pieces designed and built by Schumacher, you know it is a Made in the USA part.

Jeremy,

I don't quite understand how you can break both mounts, especially chained down. Once I strapped mine never broke another and the ones I did break were driver side only. Lucky it didn't screw up my hood because that thing would sure jump up under torque..

Yeah, the passenger mount is worse than the driver side. The passenger side is full delamination. I'm not quite sure how I did it either. I'm actually planning on adding two torque straps from Schumacher. A drag race car that I used to get to help with had both a front and a mid plate. So, I'm planning to use on of the straps on the passenger side where the engine and trans meet to kind of act like a bid plate.

What can I say, I've got "skill"?
