It shows some with 4.5 BS but they are on the rear. And since it even shows up to 5.75 BS, I don't imagine you will have any trouble with those wheels in the rear. The only problem I can see is the potential to be really close to the spring in the front (i believe 17s are big enough to be out of the way of the
control arms). If you have the UCA Shelby drop, it will be even worse, but would make your outer fender clearance better. When I do mine, if I run into fender clearance issues, I plan to do the drop so that the tires will lean in around curves instead of out. That should be enough to fix that problem.
But I do see some 17x8s with some pretty thick backspacing on there and with the shelby mod. If those can clear the spring, you should be ok.
I talked to a wheel knowledged guy at Summit Racing here and he told me as long as I don't go any wider than 8s, I shouldn't have much trouble. But he did recommend putting 7s in the front. Just in case.
I have a buddy that used to have some sweet rims on his 64.5 back in highschool. I'll ask him tomorrow what he used to have on it. He used to drag it, but it was also his daily driver (until someone nailed his rear quarter). I'm thinking they were 16 inchers, though. So, not sure how much help that will be.
If you do get 8s all around before I get my rims, I would love to know how it works and if you run into any problems. Like you, I've been looking for awhile but still haven't made the final decision.
