I'm going to upgrade my motor mounts to Prothane. Its probably something I should've done a while ago and/or while installing my headers but, my question is this.

Since the LT's are already installed, will there be any clearance issues getting the original motor mounts out?

I assume if I can get the originals out then the new will go in fine since they're smaller.

Should not be a problem I was able to put the stock ones on after I had installed the headers.

davisr014,

Why did you put the stock ones back on?

I removed them to install the LT headers.

My bad, I thought you were saying that you switched back from heavy duty motor mounts back to stock.

Does anybody not like the feel of Prothane or Steeda mounts? Isthe ridetoo harsh?

or

Has anybody changed just one motor mount? The one on the high torque side? Would there be any downside to doing this?

Change both sides. The factory hydro mounts actually sag a bit with the weight of the motor, you'ld have a leaning motor if you just install one.
I installed my prothene mounts a few months after the LT install, you'll just have to jack up the motor to get the factory ones out, as they extend down into the frame. Once they're out, the prothenes are simple to install.
Only thing I don't like about the Prothenes is my Shaker scoop doesn't 'shake' anymore, it just twitches.
Slight amount of vibration below 2K, no other vibration being transferred.

I'm getting headers installed soon, they're sitting in my kitchen...well, I asked my installer, the best mustang guy in southern NE, if I should upgrade my motor mounts while the engine is jacked up, and he talked me out of it. I was going with the Steeda MM, he said every car he's upgraded the MM in, the owners complained of excessive vibrations due to the stiffness of the new mounts. He said that my car is an 08, and the MM are fine, not to even worry about the headers hitting anything due to motor torsion when I romp on it. Just relaying some info. I've decided to take his advice, and NOT upgrade my MM.
