Brad- On a mild “stock” engine I would expect to get 10 to 20 years out of a set of mounts, provided they did not get oil soaked. It’s likely that you got poor quality replacements.
Poly mounts will be a little stiffer than rubber, but should not be noticeable, especially with a mild engine. Another benefit is that with Energy Suspension mounts, they are locked, so they cannot come apart. Visit your local FLAPS for more information. Probably available on the web as well. I run solids on my 64 with a healthy BB. It cured a problem I had been having with the stock mounts deflecting enough to allow the trans to twist and not engage 2nd gear under full throttle. With a balanced motor I don’t notice the vibration from them, but I do really notice the solid lifters and other mechanical noise.

My Chevelle is no monster, but my driver side engine mount just let loose and I replaced it about two years ago. The previous one lasted maybe ten years, which seems much more reasonable. Do you think I just got a crappy mount? I'd hate to go solid, and I think that even the poly mounts would still transmit a lot of noise and vibration to the car, but I also don't want to be replacing the darn thing every few years.
