Franko,

About 3.5" is what I have with a 427SO and a Canton Pan. What kind of trannie are you planning? That can make a difference. If you're planning adjustable coil-overs, that can help. But mine is set-up so the top of the tires is just about 1/2" visible in all four wheel wells.

I have a toploader with Lakewood Shatterproof bellhousing that was also cut off at the bottom to match the clearance of the Canton Pan.

It works OK, and I've never hit anything, but you have to be careful. Since the pan is so far back from the front wheels, you need to avoid things like speed bumps.
