What are the best motor mounts to buy. I have the motor out i might as well replace those too.

 

There aren't that many options. OEM replacement, parts store replacement and poly mounts. The poly mounts will give you a slight vibration at idle, some may be able to live with, but it if you want your car to feel like a caddy then your probably better off with the OEM. I went with energy suspension poly mounts and they don't vibrate all that much, i'm happy with them. They are also about half the price of OEM ones.

 

i have the prothane mounts and they dont vibrate as everything think they would. i also have the tranny mount. theyre great.

 

are they better for more horse power? or what is the difference?

 

The poly ones are stiffer so they dont let the engine move as much. They are a must for vehicles with higher hp. They also last longer than the stock rubber ones and wont sag after years of use. I have the poly tranny and motor mounts and they dont vibrate any worst that stock, a little less i think.

 

I also got the Prothane Poly Mounts and I paid around 45.00 bucks for the pair. You can't beat that price as I'm pretty sure the stock GM mounts cost alot more then that.

 

where can i buy the poly mounts at?

 

www.thunderracing.com and I'm sure a few other site sponsors carry mounts as well.

 

I bought new OEM mounts when the 383 went in. I had no issues with them and they have worked flawlessly since I have had them in there

 

I bought a set of Moroso solid mounts. The viberation is not as bad as I thought they would be
