What ever you do, make sure you do coils. I own one for my business and did MSD coils in it (4.6) and haven't had any failures, they are good for 200-300k. I also used my superchips tuner on the van and used the performance flash for the 4.6 and I get 2.5 MPG better mileage. Just have to be careful with pinging, bu going from 11.5-12.5 MPG to 14.9 (best) MPG s huge when you are putting 500+ miles per week.
