Motor Mounts I have some issues with my QTP y-pipe banging and scraping, and when i get my cam installed i want to keep the motor from rocking back and forth, so which are better solid or poly? advantages/disadvantages to each? i already have a poly tranny mount that i'm installing this weekend and i'm waiting for my random tech cats to come in so i can cut up and customize my y so it will clear the ground and my floorboard better.......all i need are some motor mounts now and i think i'll have this problem taken care of!

How much more does the car shake with the poly mounts? I have a poly trans mount in my 94 3.4 v6 car now and it transfers so much noise versus the stock hyrdaulic/rubber mount. When I swap in the LS1, I wont go poly on the trans, but I am undecided between the motor mounts.
I was looking at these:

and

Does anyone make tubular mounts (pedestal and upper half) that use the stock or after market rubber or poly? I have a profab K member, and as Im getting closer to finishing up and look at those huge weights, I mean motor mount brackets, I think that there has to be a better/lighter way. Should I just get new rubber mounts? I noticed a difference in my suspension when I replaced the rubber two years ago.

I am a huge noise/vibration wuss. If my poly motor mounts increased interior noise/vibration, i would have noticed. If anything there was an improvement. I would not go with solid mounts for a street car. But I know what you're saying about the heavy engine stands. Only thing I know of is I've seen K-members with "integrated" engine stands that avoid using the heavy cast iron GM stands.

Yeah, this is definately a street car. The PA & BMR K members have the cradles built in, but I already have the Profab K ammber that I purchased last summer.
I may have to make my own, I was just wondering if someone already sells them before I attempt it. Actually, I guess I would only have to make the lower half (the pedestal) as that is the heavy *** part of the stand.
I guess I'll order up a set of prothane motor mounts from Spohn.
