I've bought and run 6 or 7 Crown Vic P71s over the last 40 some years and found the 4.6/AOD combination to be a cheap to buy and run combo in a 4000lb Crown Vic. It gives excellent mileage, great low end torque, and plenty of power. I don't suffer from the need to make an EB into a dragster. I want to tour the country in a gorgeous '68/'77 EB that I can keep on the road without constant tinkering. The late as 2005-2011 P71s have a high stall speed torque converter that makes the EB very strong off the line, and the lock up OD keeps things cool. The 351 I've been running seems sluggish and thirsty in comparison. Any rebuild would be expensive compared to a JY P71 with plenty of miles left. There's thousands out there and they are all the same. I'm hoping someone has assembled the needed parts to do this very common and low dollar swap. We all want to keep our restored EBs running on and off the road.
