This may take more work than you think. In my experience, the Aerostar engine is not conducive to external modifications because the engine compartment is VERY tight (I have a '90). It also runs hotter, again because of the enclosed engine compartment, so you'd better upsize the radiator and get a high-flow water pump. I also don't see how the heck you'll get headers in there, but I might be wrong. I was not able to find anyone who made headers for the 3.0V6 in the Aerostar when I was checking this. Besides that the Aerostar is comfortable, quiet, spacious, well-made (at least mine is) and is a great highway cruiser although it suffers from body roll etc. due to the high CG and the squishy suspension. Good luck.
