383 keeps breaking mount

[Jim 68cuda]

NAPA's "Balkamp" brand biscuit comes from Pioneer:

I used one of these on the driver side when I dropped that 65-66 model 383 into Gertrude 4 yrs ago. I bolted on the OEM "strap" with it then. One of the Korean mounts serves on the passenger side. No noticeable vibrations and the engine stays put exactly as meant to. IDK WHERE Pioneer gets their biscuits. If one believes the same IDENTICAL SCREED from 440 Source and Mancini, then aside from their Exalted, Pure, All American Selves, the Forces of Darkness make their unter-biscuits in a duopoly business all in Mordor and Isengard. The dread Mark of the Inferior Biscuit is: "2250." One can see that Pioneer/NAPA sells this Evil Ware too....

Anyway, I'm glad I have my strap. Asian countries DO know how to cook decent rubber, if motivated to do so.

Yes, it was the Pioneer brand that actually worked. thats what I have on the driver's side on my 383.

Pioneer seems to vend somewhat superior quality goods. I shop for that label when practical. I still suspect their rubber biscuit comes from some asian operation, but likely has better quality control than others. Be this as it may, its the brand I will seek for any future rubber biscuit purchases I'll need to make.

Good evening all,

The driver side engine mount in my Monaco keeps breaking … I Replaced the broken stock mount with one from Mancini Racing less than 2 weeks and maybe 300 miles ago and it’s ripped itself apart. I know this isn’t an uncommon issue by any stretch, but I would’ve expected a little more life than 2 weeks out of a decent mount . Are there any typical/ known driveline ( or other) issues that I should be looking for that cause this?

Just for information’s sake, the car is a bone stock 67’ , 383 4 barrel, 727 into an 8.75 rear (742 housing) . Attached is a pic of the Mancini mounts and the mount separating while under torque. Any thoughts would be greatly appreciated

View attachment 734437I think its a common problem. I have a 1966 Dodge Polara with a 67 383 4 barrel and I just had the same problem. There are aftermarket mounts out there and engine plates if you wanna go that route.
