Brandon--post up some 5.0 dyno results.

The 5.0 makes 215 hp and 285 ft lbs torque.
The 7M-GTE makes 232 hp and 254 ft lbs torque.

I searched the web and couldn't find any stock 5.0 curves--this is as close as I could find:

i got 205 rwhp 268 rwtq out of a 1990 lx coupe with just h pipe, 65mm tb, crank pulley, k&n air filter, stock timing. Source

Meanwhile, here's a thread explaining how to get 268 Rwhp and 286 rwtq on a 7M-GTE with roughly the same amount of money the above guy spent.

The 5.0 makes less power and more torque than the 7M-GTE, but the 7M has FAR (let me say that again...FAR) more potential for less money than you'd spend on a 5.0. Hell, my Supra is making well over 300 hp and 340 ft lbs with just a K&N filter, 3" exhaust and a couple of washers under the wastegate for an additional 2.5 psi boost.

In case you haven't seen it, here's a stock 7M-GTE power curve: (Note the flat torque curve)
