Are LT1 motor mounts different than regular SBC mounts? And are they different from left to right?

 

yes and yes.

 

 

I just ordered a set of Energy Suspension red poly engine mounts for my '97 Z. The ES part numbers are 3-1116R (right side) and 3-1127R (left side). The suffix letter R is for the red poly ones, if you want black poly ones, just substitute the suffix G for R in the part number, and you'll get the black ones. Thought you might want to know this info???
