Welcome mate, check out my build thread for pointers, it has pics of where I cut the front end for the rad and cooler. As mentioned your best off getting pre fabricated crossmembers, much faster and easier, but my maddat setup sits the engine around 10mm from the firewall.
And remember it will cost anywhere from $5-15000 for a properly setup ca in a 1200, when you consider driveline and suspension... Obviously depending on how much you do yourself

Good luck with it mate
