Hello, I was an engine calibrator on the Crown Vic for many years. Glad to hear it is such a well liked vehicle. The 4.6L 2V in that vehicle is very borderline spark limited. If you don't mind running premium fuel you can see up to 0.5 sec 0-60 just by adding 5 deg of spark at WOT. We had some blown cars over the years as well and they were very pleasing to drive.
Have fun.
