Poly Motor Mounts
1.) How much do they Cost ?
2.) Where do i Get them ?
3.) How bad is the Vibrasion with them?(Keep in Mind, I would like to Change Trans mount out to Poly if it would help)
4.) Does The Excess Vibration Cause Faulty Knock with them ? ( I beileve my Headers are banging the K Member so im trying to Solve that Problem... Damn Pacesetters
..)
Thanks Guys... Any Info Would be Greatly Aperciated

1.)I got mine for $39.99/pair + shipping
2.)I got mine from Spohn. A few other sponsers carry them also. F-body LS1 Prothane part #7-512
3.) Don't know, not installed yet. Adding a poly trans mount would add to the vibration though.
4.)Don't know(see above) and their going in with the pacesetters on monday because of what I have heard from people like yourself. I doubt they would cause false knock though.

Thunder, Spohn are just a couple of the sponsors that sell them.
No vibration problems here. You will get vibration from the tranny mount..
They do tighten up the movement..

Like John said they are great. I run them on both sides and theres not anymore vibration or noise from them. I tried the tranny mount, you will get drive train vibration from that. Don't recommend the tranny mount.

I bought mine from Thunder racing for like bucks. They are not too difficult to install, although I removed the engine from the car. =D Anyways, I love them. The engine does not shake around nearly as much. The car does has more vibration, but I like it. Gives it more of an old muscle car feel. It sets no false knock codes. I have hooker longtubes and they never bang anything.

I bought mine from JcWhitney
Prothane Mounts
Trans and Motor mount combo kit P/N 7-1908
Torque arm bushing P/N 7-1609
Total with shipping $78.95
The motor is alot more solid now and I noticed a little more vibration in the car but not that bad.
I also just put Pacesetters on and if I didnt they would have been hitting the bottom of the car
