Update:
Since I started the thread I have replaced the Camshaft position sensor, Crank sensor, and MAP sensor as these were all not replaced 5 years ago when I did the swap. Did not change anything.
I never did have a ck engine light until two weeks ago I got P0175 rich on bank 2. Cleared the code came back a few days later.
I have a constant 58 psi fuel pressure at idle.
It seemed to only do this when under load and when the engine was warm.
Even worse with the AC on.
Then I replaced the Mass air flow sensor and still no change.
Two days ago I replaced the spark plugs and plug wires again (were replaced when I did the swap 5 years ago).
Now it seems like it is fixed. I have driven it about 60 miles and seems like the problem was solved.
When I inspected the plugs they weren't fouled out/black and all 8 looked the same.

If it comes back I will keep everyone posted.
Thanks for the help.
