I was almost convinced that the 4.6 was the way to go with their smooth revs, great power curves, smooth shifts, and the fact that they come in cars with much better ergonomics until I found out that their durability can't shake a stick at a 5.0. Almost everyone I know with a 2v 4.6 has blown theirs up some way or another. Two of them had nothing but exhaust and they blew out rings with relatively low mileage-one at 70K miles, and the other at I think 40K miles. Granted these cars were driven hard, but my '93 Cobra was driven just as hard and NEVER broke, and never gave me a lick of trouble. The 5.0's may seem to have more problems due to their old age, but they are much harder to break, will take just about anything you can throw at them, and parts are much cheaper. On the other hand, a 2v 4.6 will take lots of $$$ to go just as fast thats why you will see so many people run a stock 99-up PI motor with a Bullitt intake and superchargers because anything beyond that costs way too much to build. So my vote is with a 5.0 or a 4v 4.6, I wouldn't waste any time with a 2v. Just my .02

450 HP... Over 60,000 miles.... I would say its quite durable...
It's all in the tune my friend....
