Thread: Are there better motor mounts than stock?

Tweet

Stupid question, I know. There has to be better ones. I have a 350 in a 46 Chevy truck. There is a lot of movement when I accelerate, and I would like it to be stiffer. I have an idea for some trick exaust, but there cant be a lot of movement for my idea to work. Yes the current mounts are stock (looking) and not broken. Any suggestions? Drawbacks? Thanks -M

Rubber, are best to absorb vibration .Then you have poly mounts ,and then there are solid mounts.

Remember the more "stiffer" the mounts the more vibration you will feel and hear.

My idea on my truck is to use rubber mounts and torque limiters.They will help keep the engine from twisting,and the rubber mounts will keep vibration down.I am planning on a big block for built for street strip,mainly strip and occasional cruize night.I know I will love my motor ,but dont want it to get real annoying on longer cruize trips.

Thanks The Poly is like hard plastic? Explain please. and how would the torque bars work?

Say I go the middle of the road, Poly, how bad could the vibration be? I had a solid mount in my harley, and the bars were mounted almost solid. After about an hour on the freeway, my fingers were numb. Cant have that.

Like this ,but not reall y removable.Even if they are not ever removed you get the benefits of the rubber mounts being the quitest (engine humming onthe highway).http://store.summitracing.com/partde...5&autoview=sku

Another thing from what I have herd (and common sense),you don't want a mount to fail when punching the gas ,bad!

Exactly. I have ripped a mount before and its ugly. Wouldnt that strut from summit, transfer tons of vibration? I was just remembering in the early 70's, I think, there was a safety cable , GM as I remember, on one motor mount, just in case.

It would ,I would not says tons though ,and yes they do offer cable, and other kits.

Maybe even this one.http://store.summitracing.com/partde...5&autoview=sku

Thats what I'm talking about! That should work great. I bookmarked the summit site, I need to spend some time drooling on my keyboard while looking through the catalog. Thanks BTDriver

No problem ,glad to help.

2 bolts and a short piece of chain...............

they improved the mounts now so they can't come apart. stock mounts are ok unless you want solid mounts for some reason.

Yeah, what Mike said. If you can't find the good mounts with the interlocking metal on each bolt flange, then there's always the old street racers trick of drilling two 5/16" holes through the mounts, install a bolt with a self locking nut tight enough to hole the pieces together, but still loose enough to allow the rubber to absorb some of the vibration....

Nice trick, thanks.
