The three really need to be tested at the same time (same ambient temp's, etc) for a valid comparison. As mentioned, the numbers don't seem quite right.
Was the GT350 an actual "production" car or was it a pre-production car supplied by Shelby? And as to the 1/4 mile times, specifically that of the GT500, you have to look closely at the comments M/T made...
The GT500 struggled off the line, proof that power means little if it can't be fully utilized. "A tough car to launch, with tons of power at low rpm," says road test editor Scott Mortara.
So the GT500 overpowers the tires - we all know that and what it takes to remedy the situation. MM&FF had some interesting times with a stock 2010
(3.55's, etc) and some better rubber...

MM&FF tested a 2011
car in the midst of Florida's heat...
As the night went on, the mid-90-degree Florida air began to settle into the 80s, and the e.t.'s kept dropping. Smith wheeled his way to a 12.51, then a 12.25, followed by a 12.05 at a very healthy 118 mph. Back in the pits, we used ice and fans to remove heat from the 5.4L, and each time we cooled it to below normal operating temperature, Smith headed to the line for another pass.
After a smokey show to clean off the Goodyear Eagle F1s, he launched hard and was quickly away from the starting line. The MM&FF staff watched from the starting point as Smith grabbed Second and Third with a bark from the rear hides vocalizing at each gear change. The run was smooth and straight, and as Smith shifted into Fourth, we knew this would be one of the quickest passes of the night. The scoreboard lit up with 12.02 at almost 119 mph! We were excited to be so close to breaking the 12-second barrier on the stock tires, but unfortunately, the next runs did not yield better times.
It would have been interesting to see the GT350 and a Boss run that same night, as well as all three with sticky rubber. Then again, with Justin's wife turning out such good numbers with her blown automatic five liter, does any of this really mean anything? Simply put, they're all good!!
