Yeah, I put a 7M-GE in my '85 pickup and was worried that I wouldn't pass so I Aircared it right before I did the swap (as in 3 days before) so I would get as long as possible before having to worry about it.
It went something like this...
- Aircare with the 22R-E
- Insure vehicle for 1 year
- Aircare again a few days later with the 22R-E
- Engine swap a couple weeks after that
- 11.5 months later, my insurance expired 3 days before my Aircare expired
- Another full year before having to actually get tested with the 7M
Since I had been tested (and passed) just days before and there was no normal reason for me to be requesting a second test, they made me sign some form saying that I was voluntarily getting tested. The guy thought I was nuts but I just told him I did some major engine work and wanted to make sure I was still "legal". Right.
When I finally got the test done, it passed by a long shot so I had nothing to worry about all along.
