They did Sherpas with the Rover V8.......................................
Did they?? 😱
The V8 engined Sherpa came about because at that time Ford Transit vans were available with the V6 engine and an overdrive gearbox. They left the Sherpa van of the same era standing. The manufacturers were approached by Plod, with a request to graft the Rover V8 engine into one. That was duly done and as they say the rest is history. Nice vehicle to drive with V8 power, as was the V6 Transit. The V8 Sherpa came with a 5 speed gearbox as against Fords 4 speed with overdrive on 3rd and 4th.
I've seen a vehicle built in the style of a vintage bentley built off of one of these with the beam axle and leaf springs it got fairly close (main thing it needed was much bigger wire wheels, it had what looked like mgb ones)
