If its not mechanical, some out of balance thing, spark or fuel is about all thats left.

Just revving the car produces nothing, even at the same high RPM's. The car has to be in motion for it to do it.
As soon as I let off the gas, it stops completely.
The car does have a slightly rough idle and is definitely missing a bit on the way up. As of right now, it's not running nearly as fast as your normal GT. Could the timing being off a little bit produce such a shutter as this at higher RPM's? I was going to have him check the timing when he got back anyway, change the plugs and if necessary, the plug wires. Could that be a possibility?
It does feel like something is totally out of alignment, like the driveshaft or something like that. I'm certainly no mechanic, nor do I pretend to be, so I'm simply throwing out things that it feels like it could be if you didn't know any better.
