Default Motor Mounts

Since I am already way over budget on the top end rebuild.. why not go even further? My motor mounts are shot.. to say the least. My engine moves like Bill'* video of his CAI and the whine it made with just revving it in park. Either way, I know it also contributes to the hard shifting in reverse and such.. I just want it tight. Looking at gmpd it'll be way over $100 for all the motor mounts.. I don't have that kind of money to drop on just motor mounts. I remember a while back Straitor gave me a diagram for a hockey puck in place of the motor mounts.. and he said he got the idea from one of the other members [someone who'* fast.. that'* all I remember].. so I was wondering if I can use that concept for all my motor mounts.. because four [I have four motor mounts.. right?] hockey pucks aren't going to be expensive. Do you think I should do this before I put the engine back together to help with weight problems? Should I just do one or two that are causing my torque [or lack there of] flex? I want my engine to be firmly planted in that cradle for when she takes off.. that way none of the power is wasted .

Have heard people who replaced mounts with delrin complain of noise and vibration. Steel is worse. No idea about hocky pucks but have to wonder how they would stand up to heat, oil, and grease. Second at least in the driver'* front you would have to stack a couple of pucks to get the same height. Finally a real motor mount contains retainers to prevent bad things from happening when a mount breaks that a hockey puck will not have.

Hmm.. I don't know..

Are you saying the GM motor mounts are really the only thing I should put in? I have never seen the car new, so I do not know how lose the engine is.. but would they be tight enough that the engine will only really flex when you are at WOT? Ultimately that is what I am looking for. I think the hockey puck could hold up to grease and oil and such.. but even if it can't, wouldn't it still last a while? A while being a few years.

I feel that engine mounts are one of those things you shouldn't go ghetto on

Yeah.. I agree, but in theory it sounds better.. because less torque is wasted on engine flex. I just want my engine to be planted.. that horrible Reverse Engagement shake had really been getting to me, and I think the new mounts will help correct that [along with an ATF flush].

I had to get aftermarket mounts, because GM discontinued them. Careful though the first place gave me the wrong ones and they tore up in a week. Make sure you get ones for GX3 trans. One was liquid filled or something. Real pain to do twice.
