Who sells the best stock rubber engine mounts? I can't seem to find the GM part # and reviews for these.
I don't want poly.
thanks all

GM hasn't sold a small block in years, doubt they manufactured the mount inserts themselves in over a decade. You might find AC Delco on Rock Auto, but chances are better than average you'll get some discount brand in an AC Delco box.

I get that some people hate poly because it squeeks or it's harsh... I'm fairly picky and my personal experience was that ES poly mounts weren't at all objectionable.

Use poly, they come in black, you can't tell the difference except they they don't break, and they don't flex....

I switched to poly mounts recently (Energy) and you can't even tell the difference vs the stock rubber IMO. They are NOT harsh at all. I can't tell any increase in NVH.

And yeah - I doubt there is anyone out there making *quality* rubber mounts. There's no market for them and proper vulcanized rubber is CRAZY expensive to manufacture compared to poly.

Thanks. I have Dyno Don headers and y pipe coming in 2 weeks. They suggested stock rubber to prevent the pipe from rubbing. They said poly makes it sit too high and pulls pipe up with it.

I have Dyno Don headers and y-pipe. They were installed with worn out rubber mounts that I have since replaced with poly and I didn't have any problems before or after. The poly mounts did pull the engine forward about 1/4" and I had to adjust the y-pipe to not hit the engine cradle. Wasn't a problem though. My headers don't hit anything.
