There probably won't be any MOT or VED requirement, and if you licence it as private there'll be no PSV requirement either.
The only hurdle will be registering it to drive in the UK.
Can you get it licenced in the USofA?
That should allow you to drive it initially on the roads in Britain as a temporary import. Otherwise you might need an SVA.
No:- You don’t need vehicle approval for:
heavy goods vehicles (more than 3,500kg maximum weight) over 25 years old
light goods vehicles (3,500kg maximum weight or less) over 10 years old
cars and minibuses with 8 passenger seats or less (not including the driver) over 10 years old
buses, coaches and minibuses with more than 8 passenger seats (not including the driver) built by a single manufacturer before 29 July 2010
buses, coaches and minibuses with more than 8 passenger seats (not including the driver) with different body and chassis manufacturers, made before 29 July 2011
