Disagree with always, the 302/351 were better than the 305/350 until the Vortec 350 showed up. The Vortec brought it's own set of issues though. IMO, the 4.6/5.4 were better than the 4.8/5.3 from 99-present.
Ben maybe the 302 and 351 were better that I can agree with but you need to get off the Blue Oval for a minute if you think the 4.6 and 5.4 in truck form are better than the 4.8 and 5.4 especially when towing. Have you towed in a 3/4 with a 5.4? I have it, is painful. You can't even get a 5.3 or 4.8 in a GM 3/4 ton. I know you are a Ford guy but be realistic. The GM stuff even get better mileage. Just take a look a the RV boards or any campsite for that matter.
I haven't towed with a 5.3L, but I know my 5.4L will out-tow my uncle's 4.8L with ease. Though he gets much better gas mileage than I do.
I don't think any of the above engines are good for a 3/4 ton or larger. You need something like GM's 6.0L, Ford's 6.2L, Dodge's 5.7L...etc.
My buddy Jon on here (slammds15) has a 6.0L PSD (I know, and it has had its share of issues) that works very well, and has a tune on it. IIRC, "3" is 450/800, and we've towed something like 5 tonnes with it and you barely knew it was there. After experiencing that, towing anything with a gas engine.... Just felt "inadequate" LOL
