Motor Mounts, which is correct

390 engine, do I have these on correctly? Or upside down?

Are those "2 bolt mounts" the ones that were previously installed on the block?
I'm thinking that you need the "4 bolt motor mounts" since there are 2 empty holes in the block right next to the motor mount.

This engine has not been in this truck before. It's a build I had done by a guy in Tennessee. I just grabbed my old mounts to test fit this in the chassis, but I couldn't remember how they came off.

4 bolt mount? Hmm, not sure I've seen those. I'll have to look into that.

I have egg on my face....in looking further into this, I read that Ford added a second set of mounting holes into the block for the later year models use of a 3 bolt mounting bracket.That being said, I now believe that you need to use the 2 holes closest to the center freeze plug. As far as it being upside down, my engine blocks have "TOP" cast into the rubber edge. Sorry for sending incorrect info....

Thought I would re-visit this topic for clarity after recently swapping mounts back and forth.

I compared the 2 bolt mount with the 3 bolt type and they put the mounting stud in exactly the same place. I have now bolted up the 3 bolt mounts and plan to leave these in place. It seems that it's just 2 different ways to accomplish the same thing.
