3000 stall convertor and 2800 highway cruising

No. It'll be fine. I run a PTC that flashes to 3200 and 3:55 gears that cruise at 2700 @ 60. No problem at all. Just make sure to run a good auxiliary cooler cause when you stomp on it the slipping effect (flash) builds heat.

I run a 2800-3200 with 3.55 gears with 28" tires. No problems at all.
I use a B&M tranny cooler....keeps the fluid between 150 and 180
