73 Engine Mounts
Does anyone know if the engine mounts for this year are offset by 1/2".
It appears as if the mounts bought need to be offset by this amount, the mount on the driver’s side from underneath needs to go 1/2' toward the front of the care and the passenger from underneath needs to come back 1/2"?
This is fully aligned with the transmission mount.

No just looked to see if I had them. Bought car and some had already gone through engine. Found build sheet and rebuilt original engine again it was 30 over already but worn out. It's 60 over know and sitting on an engine stand and bought a 383 stroker for fun for the next couple of years until total rebuild of body. Had 2 types of SBC mounts 2 smart mechanics helping and we are all stumped. Figured someone might have run into something like this/

They are 2 of the same; i.e. not right or left specific. The block mount holes correspond to the saddle mounts on the car's frame, which ARE offset. Offset for same reason that #1 cyl is not parallel to #2 cyl.
As I just installed my motor the other day, there is a front-to-rear gap as the mount sits on the frame saddle. I didn't measure 1/2" in mine; it was closer to 3/8" but that may just be manufacturing tolerances.
Does this offer any help?
