275s are known to fit on the back of a 67 without rubbing with the correct backspacing.

I know I remember reading somewhere that you can go bigger than 275 with the right wheels
I have 17x8 with 4.75 backspacing. I can get away with another 1.5" of backspacing. I bet you could get a 305 maybe 315 to fit but it would be close. I know people who run 17x9.5 rear tires on 67-68's with not clearance probs.

The biggest factor is how low you want the car. My coupe has 5.94" backspace 18x9s with no spacer and 275/40 tires. The Global West leafs have been dearched an additional 2". The return flange on the wheel openings have been rolled but ironically at this ride height they do not matter much. I was running an 18x10 with 6.37" of backspacing, no spacer, and a 295/35 tire. The top pic shows how far inside the lip that they rubbed on the oustide and if you look real close in the bottom pic you can see where the paint rubbed off in the lower corner of the inside wheelhouse.

As far as ride height is concerned, I like the level it rides now, which is on stock, sagging, rear leafs. I plan to remove a couple leafs and install an air-ride bag over the leaf. This will not only let me change the stiffness of the ride, but also the ride height.

with stock wheel-wells...
and a 55 7/8" shortened rear end with 5" of backspacing
17x11's with 315/35/17's

Whey the need for a shortened rear? Couldn't you just use a wheel with more backspacing?
The wheels look sweet but it doesn't look like you have much suspension travel. I know those rear wheel housing curve upward above the rear lip, seems like the tire would hit there.
Did you modify anything else? Other than the fender lip?

I have been mocking up my 'stang with 275 40 18's. I have lots of clearance, with slightly modified wheelwells, probably 1" gap each out side, and 1 1/2" inside, with partially rolled fender lips
A local tire guy, is pretty interested in my build, and gave me a 315 35 19 to try out. It was too big, I think. I have 1 1/2" lowering springs plus 1" lowering block. I don't want any rubbing. He will give me a couple other sizes to try, when I am ready.

Let's switch it up a little bit... I wanna know how to get the biggest FRONT TIRE on these cars with stock fenders (rolling of lips permitted). I have the 275-40's out back... but I need more grip than the 235's up front are allowing!! Yes, 17" wheels. Is it just a matter of backspacing? What are the mechanical interferences I'd be running into?

My question, 100%. I have been working on this.
One thing for sure is that the stock upper control arm and spindle arrangement really limit front wheel/tire width. I've asked griggs if thier setup would allow the 275 and they didnt give me a definate answer except that it might require flares... Then I found this:http://www.jktaylor.org/gallery/griggsinstall
Uses the stock 275-40-17 tires from the 03-04 cobras. 17x9 wheel. My project is long-term, so I might actually bite on the griggs stuff, but it is very pricey
