Best engine conversion in a van?

I thought I'd post this topic after seeing so many vans with a variety of engine conversions over the years.

My favourite is "Alley Cat",the Holden van with a Jaguar V12 engine.It was good to see something different.Is this van still out there somewhere? I remember seeing it in "Custom Vans & Trucks" with a V8 then in a later edition of the magazine with the V12.

There were a variety of big block V8's too.Some small vans ended up having a V8 fitted too.

What engine swap was your favourite?
