Hey everyone, I'm going the cheap route for now and just filling my motor mounts with 3M Urethane. The question I have is that since I'm only doing one mount at a time, I'm wondering which mount would I see the most difference for straight line acceleration? I'm thinking the front motor mount, but I'm new to all of this, so any advice would be greatly appreciated

 

I filled in the motor mount on my '88 Shelby Z with black silicone, but they didn't go on for a week so they had time to dry and harden. I don't know if it will do any good or last if it is put into a daily driven car, not given drying/curing time. As far as which to do first, that depends on which way the engine torques.

 

thanks...I'm going to the local junk yard and picking up a spare front motor mount for $10 and I'm planning on filling that one first. I was only planning on letting it cure for 3 days, but maybe I'll take the safe route and let it cure for a week like you did. I should be going to the drag strip this coming friday night, so I wanted to have it on by then, but now that the weekends done, I wont have the time to start any of this till next weekend. I'll let everyone know how it works when I get it done[8D]

 

We'll be waiting. I only waited a week, because thats how long it took before the tranny rebuild was done.
