Question Where to get the best rubber motor mounts

I need to get the rubber motor mounts for my 66 but have seen some very cheesy mounts lately. Anyone have a recommendation for a good, heavy duty, rubber mount ?

Sounds like a deal. You can't beat a pair of eyes looking at the actual part...

Actually, the pic on NAPA's website is what prompted this thread. I've bought mounts form them in the past, but the pic is of the cheap ones with the washer welded on to reinforce the weak sides. Maybe it's just a genaric pic...

First Guess: There's no such thing as a good rubber mount any more. They're all made in India and China. Probably including the ones GM sells, so they're not lying about using the same manufacturer.

I could be wrong. In fact, I hope I am wrong.

Good luck.

Good luck.
The pair of mounts I bought last July from NAPA were from India and they had the extra washer welded on the inside for narrow frame stands just like the MityMounts pictured in the post below. I'm assuming the MityMounts are made much better than the India mounts for 4 times the cost.... My engine isn't any power house so I'm leaning towards getting them from NAPA for now and research the MityMounts better for when I start to "enhance" the 454 for better performance.
Thanks for the link F1, I will look into them more...

Default Re: Where to get the best rubber motor mounts

The MityMount web site scares me.

I have zero experience with the product. Maybe they're everything a person could want in a mount, and more...

I look at the photos, and the "cutaway" drawing; and I get REAL SUSPICIOUS.

I see what "could" be flat-head screws and countersunk holes with some rubber in-between as an insulator in the cutaway drawing. The drawing is done without showing the threads on the screws, though. (so the two screws and the base metal appear to be a single piece.)


I'm seeing what looks like a couple of flat-head screws (which would go into a countersunk hole) in the center of the motor mount photo. The screws seem to have a recessed (allen socket??? Torx socket???) wrenching surface.




First Guess: The Mity Mounts are Made-in-India (or China) ordinary rubber mounts with a couple of screws threaded into them to control separation. IF (big IF) this is the case, a handy person could duplicate it by buying a pair of ordinary $9 motor mounts, and four high-strength fine-thread flathead screws and jam nuts--perhaps 5/16 or maybe 3/8, I suppose; and drilling 'n' tapping 'n' countersinking appropriately.

Seems unusual that the company "headquarters" is in California

Most aftermarket mounts are produced overseas, and the quality of rubber and production varies greatly.
Yet nowhere on the web site do they claim MityMounts are "Made in USA".


Quote:
This [stock sandwich motor mount] design typically provides good isolation from engine vibrations but stretches under acceleration. This wastes horsepower
Quote:
Power is transmitted without excess motion and resultant power loss.
How much power is lost due to motor mount distortion??? "Not enough to notice" would be my guess.


BK 6021054, $11.00/pair from NAPA.

Note the two flathead screws, one is mostly hidden by the flange of the mount.
CH2, $129 (presumably for the pair) from Dynatech

Might be worth some follow-up before spending that much money for motor mounts. If I'm right about this, they don't have $29 in materials; really, it's between $10 and $20 for the pair of mounts (probably less) and a few dollars for hardware--screws and perhaps jam nuts; plus the labor to install the screws--and they are getting more than $100 in gross profits per pair. I call that "excessive"!

Shurkey, that was my first impression too and you took the research and ran with it.....thanks. I don't think I will be getting them.

Tha Lakewoods look interesting but they don't specifically list a 66 396. It appears the 24087 would work, since it is listed for other 67 up big blocks. It also appears to be the narrow mount with heavy gauge sides and no spacer washers....
