Besides going to a solid motor mount or strapping down the motor is there a motor mount made that won't separate with 400 plus HP?

AMES has a new lifetime warranty set that are really nice

If you are using the older "rubber block" mounts they sell whats called a mity mount for ~$100+, its basically a stock mount with a bolt through the center... or do what I did and make your own for the price of a grade 8 bolt an an hours worth of time drilling and tapping the mount. Has help up with 500+hp & lots of low 11sec runs... I did install a limiter chain just in case the mount breaks but after about 7 years with lots of street use its doing fine. I have a 2nd gen Fbody but they sell the mounts for other cars too, think there was a write up on making a stronger Abody mount too.

The new AMES one is not a mighty mount. Call them and ask about them, they sell basic, mighty mount, and then the lifetime warranty ones

I`m using those now at 600`ish hp. Holding up so far. Used to run solids but figured i`d take some "stress" off the block.

I'm using these from Butler at around 500 hp and so far so good. They are really stiff. Functions almost more like a solid mount I think but doesn't feel rough or harsh driving it.

I've used stock replacements..no issues and I have a few passes on them.

The new ones listed in the Ames catalog are called 'Torq Lok' mounts. The description states it's the highest HP mount on the market aside from solid mounts.

I would have gotten a set if I had noticed they were available when I purchased my mity mounts.

All the poly ones get eaten up by heat and crumble if you run headers.

Thanks for the replies, I am aware of the Butler poly mounts but they are heat sensitive and with my RA/HO manifolds don't think they would work. I may try the Ames life time warranty mounts. Wanted to see what was available as new stuff comes out from time to time.

I was told no polyurethane with headers also.

I’ve had the poly mounts on my 69 bird with long branch manifolds for several years and no issues.

I have the butlers on my GTO with RA manifolds - 500 miles and no issues .

Butler has a warning about using them with headers.

"If using headers, ceramic coated headers are highly recommended AND/OR a heat shield or header wrap to keep heat away from the Poly mounts as excessive heat may cause the poly to melt or deteriorate."

I have about 1700 miles with RA manifolds and no problems.

Yeah, I saw that warning too.


Mine have been on the car for a few years now with 1 7/8 headers. One of the tubes is 1/8 inch, at best, from the metal mount frame on the pass side.



I have at least a few thousand miles on this thing. It`s not a daily driver but I do use it as much as I can. And it gets used in the hot ambient temps we usually have down here.


I look at em at oil changes since my a$$ tightened up after seeing the warning. So far, I see nothing. No bulging, cracking, etc.

The design of the Butler mount gives more clearance than more traditional style mounts. With RA manifolds it's pretty good. Obviously with headers it's a different story. Also with bigger/bulkier style poly mounts may even be an issue with manifolds.

Never saw a mount like that. Where did you get that?

Butler sells them. No idea who makes them.
