I have a '68 SS Camaro, with internal-balanced 454. Motor is fresh and everything is pretty new.

I'm getting some engine vibration through car, which is very annoying. I have a pretty big cam with a lopey idle and I don't mind the vibration at idle, but it should smooth right out once you get rolling.

Currently using poly engine and tranny mounts. I think I'm gonna switch back to factory-style rubber mounts.

Anybody got any thoughts on good, factory-style mounts? Are there any aftermarket ones that are designed to be a little softer and maybe absorb vibration better?

Thanks for help

:)

I'm using the GM engine mounts and tranny mount on all my cars,..two SB and two BB's.

I would recommend using GM and not something from an Autozone type place. If you compared the two side by side, you'd see my point.

You'll pay about $30/per from your Chevy dealer for the two engine mounts and about $20 for tranny mount.

Don't expect to ever be as smooth as your father's oldsmobile. It's kind of like the harley guys - the vibes are part of the ride. My 2002 Z28 is plenty noisey mainly because of less suspension travel with polly urethane rubber. So it's a trade off. Rubber mounts will flex more under torque, but dampen vibration better. Same goes for subframe bushings. The high-power guys often replace the subframe bushings with solid aluminum bushings. Imagine the rattle that would give.

But perhaps the simple solution (but not necessarily cheap) is some improved cabin dampening. Dynomat and other types of weighted dampening materials can help get rid of that deafening hum that sounds like an old wheat truck in low gear.

Yep, I put lots of this stuff in there; in door panels, in trunk, under carpet. Entire floor pan has brush-on coat of special deadener, then front section has metallic-layer deadener (real expensive).

These types of deadeners are good for reducing road noise and such, but they won't kill a chassis vibration, nor does this deadener stop the interior droning of Flowmaster mufflers (soon to be replaced with Magnaflows).

thanks

I'm definitely gonna buy the GM mounts. Good tip there.
