This all makes me want to call brown dog back and order other motor brackets.

I wouldn't get the brown dogs unless you like the feeling of sitting in a massage chair. The vibes were very bad. I can't say anything about the other brands.

The brown dog poly ones are good once they break in Alitte.yes at first you get alot of vibs .i did especially since i have a larger cam shaft in mine !

Even the rubber ones? How come everyone else who has the rubber Brown Dogs says the opposite?

Maybe they weren't torqued properly.

they vibrate for a few days, but smooth out after. just follow the torque specs and you will be good to go.

i have the prothane engine and trans mounts and she's a vibrator.... the chicks dig it... me not so much

I like solid mounts. Feels like you're flying an old biplane. LOL

pull a plug wire and throw on some goggles for maximum effect

I have the brown dog rubber mounts love them huge difference over the crappy stock ones. The vibes lasted a few days but nothing crazy enough.
