Yea guys, ya can't fault him for that swap. How many Pontiacs are in South Africa? Well we know of one. Chevy parts have more of a reach around the world. Maybe if we had more of a military presents in that part of the world, there would be more Pontiacs like in Europe.
Rob, as pointed out having contact with the Camaro crowd will be helpful. If a SBC is in there already, then your mods of frame mounts and wiring changes are already done. The only thing you will have to consider changing is your front coil springs for the additional weight. Also you might have to beef up you cooling, bigger radiator and better fan.
Hmm, now all we need is a Firebird on Antarctica and we'll have all the continents covered.
