I was going to do this to my FB, but have opted to go for the Hot Rod style instead...
have however done this to an LJ, and a had a setup in his HG Monaro, firstly it depends how much power your after, drivability, and cost.
Back in the UC Torana days, Normalaire Garrett made a bolt on kit to a stock 202 red motor, ranging up to 450hp so they say, using a webber and water injection.
I have a kit if your interested in really good nick, just pm your email and i can send photo's and discuss with you.
the only thing required is a line put into your sump for oil return and the exhaust done
then it comes down to what sort of work you do to the engine, i was going with hi-vol oil pump, electric fuel pump, decomp plate, roller rockers, turbo cam nothing fancy, would have been good for a bit of fun.
