It's hard to say a recipe for any particular car, they are all so individual by nature. I intend to build one in the future, but this will be the shop race car, and it'll have a full glass body. If I had a steel car, I'd probably replace the factory floor pans, and repair the rest of the rust as appropriate, you can smooth the firewall easily and the other areas too. I wouldn't personally go too wide on the rear tires, because the front tires will only be so big from a packaging aspect, and too big in the rear will hurt the ultimate cornering balance of the car. I think a 245/275 front to rear, maybe as high as a 295 rear is about right from a grip to aesthetics standpoint. If you move the motor back, that will better help the balance and the seemingly small-ish front tires will work better than one might think (r compound tires, please...).
There really isn't a good front setup that I have seen, at least from my own perspective, I am sure others will have their own opinions (it's what makes the world go around, and there's nothing wrong with that). It's a tough place to be in currently, but help is on the way in the future. For the rear, I am biased to the three link. Especially with a very high output motor, you need to be able to plant the tires firmly, and the setup needs to be strong, there really isn't a big downside to running one all things considered.
If you don't have an engine already, consider a turbo V6. Yes, really, you can save even more front end weight. If you are core, dry sump it, and drop the motor down as far as possible. Setting it back will become less important, but still a great idea anyway. I guess what I am getting at is if you want to build a real burner, a pre-68 Nova is the perfect candidate, and keeping it as light as possible is going to help EVERYTHING else out. It is the perfect candidate car for a super high performance buildup. I just wish the darned things weren't so expensive now!
