idk, i'm kinda maybe getting used to the change a little bit...slowly...but i'm curious as to how those things hold up and if they can hold their own against a cummins...don't get me wrong here, i'm a ford guy thru and thru, but personally, i don't think ford has had a good enough engine since the 7.3 ...6.0's were ok but i'd rather have a 5.9 cummins over that. Oh, ya almost forgot, not a big fan of all the emissions restrictions the government slapped the poor diesels w/ but then again, who isn't. Now i spose someone's gonna be mad at me for wanting to choke bunnies w/ all my diesel smog and what not lol...
