Sure he can! After having my car for almost 7 years, 3 of which with a supercharger, I FINALLY swapped out the gears! The stock LSD was also starting to give some trouble locking up. So out go the 3.27s and in go the 3.73s. First thoughts: wow, what a difference! The lag from a dig with the stock converter is nearly gone. 2nd gear pulls onto a highway are much more fun. 3rd gear (1:1) pulls with the converter locked are freakin' awesome. And ironically, the first several tanks of gas I have gotten BETTER gas mileage. Albeit they are both entirely city driving, it went from around 15-16 average to over 18 on both of them. Best city mileage I've ever gotten. I also did the swap myself. I was a little worried at first, but it was actually really easy. The only special tools needed are a dial indicator/mount, a hydraulic press, and some way to get the bearing races out (I just used a brass punch and brute force). I had no real snags on the entire install. I was able to get backlash to .0135" (recommended is .012-.015), which is pretty much perfect. Teeth contact pattern looked perfect, too. So far, I've got nearly 1000 miles on them, and they are quieter than the stock gears. I used full synthetic Mobile 1 75w140 oil with one bottle of Ford friction modifier. I also went ahead and installed 31 spline axles at the same time. I shopped around for a while, and got great deals on all of the parts (all new). In the entire build (FRPP gears, Ford bearings/install kit, new 31 spline T-lok, new Superior 31 spline axles, Superior wheel studs, oil), I've got right at $600 in everything. Not bad at all for all new parts on a 31 spline upgrade. Also, big shout-out to Tousley Ford. If you ever need any FRPP parts, check them out. I got FRPP gears for $130 shipped, and the good install kit (GT500 bearings, better gasket, etc.) for $90. They've also got 31 spline differentials at a good price. New track times coming soon!
