T-5 overdrive transmission and the appropriately geared rear axle will take care of being run over. I have a '50 with a T-5 with .73 overdrive, 4.65 rear geared 2001 Nissan Xterra limited slip rear end, and 30.5" skinny radial tires on factory rims. I can probably pull a stump and drag it down the road at 65 MPH without lugging the engine or going over 2800 RPM. I need to do that someday and have somebody video it.
