Correct Motor Mount Thickness?
 

Having trouble getting my driveline angles correct after installing TKO 600.

The engine/trans sits too high in the front to get a 3deg angle (it's 5.3 deg now)

Now I'm wondering if the motor mounts that are in it are the wrong thickness. They are 1.25" measured from the block to the "perch"

Can someone measure their mounts for thickness?

Thanks

I did a LS/T56 swap in my 68 C10 and had a similar problem. I ended adding a high hump trans cover. Then because I had to run 3.5" drive shaft due to length and HP level.
I would do what ever it takes to lower your engine mounts so the oil pan just clears the engine cross member.
I ended up at 3.8-4 degrees engine angle with a 6" rear drop. Zero vibrations.
