Sounds like a cool project. Great to see another Canadian Torino on here.
I assume you are going to significanly modify the front of the car to fit 325's up there. From what I have found, the most you can possibly fit under there stock and still have full jounce clearance and be able to still turn lock to lock is around 275. This is with a heavily modified front suspension. 325's in the rear will be no prob if you add 1.5" to the rear wheel well.
I also went the fab everything myself route and build on a very tight budget but run all top notch parts.. 4 years later still going

. Managed to do everything very cheap considering.. just took forever to find deals on used parts.
