I have had a similar idea, Darren, didn't follow through though.

But in your case, cost, must be a consideration, after all you just laid down R195000 on a running and driving panelvan.
The cost of an engine and suspension conversion can be prohibitive.
A rebuilt Isuzu KB280 diesel engine is around R20k, a more modern 3.0L D-Teq engine, maybe R35k or more.
And in the end, no matter how impressive the torque or economy, one has to consider that a diesel engine just can't give you that feeling the burble of a V8 can.
There are a lot of petrol engine options, easiest and cheapest V8 may be a Lexus V8 at around R17k, but then you are crossdressing.
A rebuilt GM 350 is probably around R40k.
Other members might be more up to date on the cost of a the GM 5.3 or LS engines.
A Jag suspension swap can go up to R40k.
A nice set of wheels can go up to R25k.
Add it all up, and I'm wondering why didn't you just start with a cheaper project vehicle in the first place.
Why not just drive the panelvan as is? If the 4.1L is tired, maybe just rebuilt it, along with the carb. You can buy a lot of petrol with the money you are going to spend converting the van.
All is subjective. How much of the work you can do yourself? If you have the money and/or skills go for it. I still believe it is a good idea, and it will certainly be a unique daily driver.
