supercharging my esky???

[seanyboy]

gday all
well thought id introduce meself and my new toy. a 1978 panelvan, she had a 2 litre that the p/o blew up. Got a few questions to.....i have the option of buying a 2 litre from a mate who races them, ported head, bigger valves, 40 thou over etc, basically its only done 10 000ks since rebuild. Im not sure whether to get it or not, it might not be a good idea to start off my first project with a worked motor. Any advice would be great, my other question was, what was the deal with supercharging an esky??? Id like to know how hard it would be to fit and tune...how hard it would be to get regoed in WA etc. Im looking for a streetable daily driver, with the grunt to have some fun with, nothing excessive though.
