Being from NZ, all our engine swaps will seem weird. Best in our area when I was a teenager was a Fordson pickup with a flathead V8. Done as a bet, because of course it would be impossible to fit a V8 in the snub nose Fordson. So the engine gearbox rear end was done dragster style and fitted in the rear....the radius rods were brought up to the front engine mount, and a tow coupling fitted...then a crossmember fitted with a towball. Six straight pipes out the back, it was really cool to my eyes.
I had a CA Bedford van with a Vanguard Six engine and gearbox, Vauxhall Cresta rear end. American viewers will know that engine from the Triumph TR6. One of my customers had her Volvo 244 engine fail down country in a remote area. She stayed in town a few days and then drove home after the local garage had fitted another engine. What they had fitted was a Nissan LD28. These are a diesel version of the 6 cyl L series engines. I don't know why they fitted that, maybe it was all they had, but it was a good conversion, and they ran it for many years with hardly any problems.
