agreed,im in Florida and ive never had cooling problems with SHO's.
And if you use the larger radiator you can't use the larger 5.0L Mustang oil filter,it simply won't fit anymore.
IMHO id rather have that extra bit of oil and filtering capacity.
Really?
I've got the 2-row radiator in my '91 with the 3.6, stock fan shroud, the quart-size Wix 51515 (Fram PH8A-equivalent) filter fits fine. Mind you I've got the Gen 3 subframe, which doesn't make any more engine-to-shroud clearance but it does move the crossmember the **** out of the way for working on the lower front of the engine.
Now, with the 2-row radiator the manifolding off the AC compressor made too much contact with the fan shroud for me to be happy with, likewise some of the ABS hardware at the left end of the radiator, but the oil filter wasn't a problem.
I moved the ABS relay bracket under the ABS valve, which ate the space where the horns were, and I want to keep the rest of that space for the cruise control diaphragm (if and when I get around to reinstalling it) so I need to score some smaller horns that'll fit out in the bumper the next time I'm at the junkyard.
Since I'm running the ATX coolant bottle in the fender and had a bunch of room right in front of the compressor anyway, I cut up the AC manifolding and had it TIGged back together to put all the messiness in the now-vacant MTX coolant bottle space:

These pix show both lines pointing straight down, which didn't prove usable in the end (the line to the accumulator needed to be longer to have enough flex in it, and having a springlock in there ate too much of the hose length) so I had to cut it again and put a hose-barb end on there pointed off a little to the left to make the hose loop about 120 degrees, but it gives you the idea.
And for what it's worth, the two-row radiator is probably overkill unless you've got forced induction or some other significantly-greater-than-stock heat load issues. Especially if you relocate the battery to the trunk (a win all the way 'round) and convert to the ATX coolant bottle to free up the extra 1.5sq ft of radiator core otherwise blocked off by the MTX bottle. I did the two-row radiator because of the extra 20% of displacement and thinner bore walls in my 3.6, I wasn't taking any chances. The temp stays wedged right in the normal range all the time. I did see 260degF pan oil temps on the track at the convention in 65degF ambient, so I'm not quite so sure about the oil cooling capacity.
(just aside - measuring a radiator by the number of 'rows' is useful only if comparing radiators with the same tube size and construction. Copper-brass tubes are smaller, so a 'two-row' aluminum radiator has as much if not more surface area than a 'three-row' copper-brass unit. Core thickness is a better metric unless you know you're comparing apples to apples.)
