Hi everyone,
I am dropping my new 350 in my 1986 pickup, and the engine mounts are not lining up.
The engine is a 1989 Gen. 1 Small Block 350 (Casting # 624) out of a 1986 1 ton 2wd. The engine-side motor mounts are out of that truck.
This truck is a 1986 1/2 ton GMC High Sierra 4wd. The engine I took out of this truck was a 70's #010 casting 350 block with identical mounts.
The frame-side motor mounts are new from Autozone, and installed in the only bolt holes they can be. They are identical in size to the mounts I took off. The mounts have 4 bolt holes with 3 bolts.
I tried swapping what side of the engine the mounts are bolted to, but that made no difference. I tried loosening bolts on the mounts to let them slide around, but still too far off.
In the picture, the passenger side mount is together (it has the through-bolt in it), and you can see how far off the driver side is. I've tried jacking the engine in every direction. There is no way that bolt is going to go in. What am I doing wrong?
Thanks!
