Well, my uncle confirmed that I spun a bearing so I decided Ill just pick up a used longblock. Searching the local salvage yards I found I could get a Series II L67 cheaper with less miles than a Sereis I L67. So my question is, what would be involved in swapping a Series I for Series II?

Full PCM, harness. To keep your tranny, you'll need to get a 96 computer i believe.... Otherwise you'll need the 4t-65e because of the computer.

but the tranny will bolt up?

Umm, I was under the understanding that PCM and ECU were basically the same thing, just ford used one name and gm used the other? Please correct me if I am wrong

They bolt up, ECU PCM, PCU whatever you want to call it.

Okay, And how hard is it to work with the engine harness? Has anyone on this forum done a Series 1 to Series 2 swap, and at what difficulty level am I looking at? Also what kind of problems would I be looking to overcome.
