i love minilites and they look great on that car.
if it were a different build, i'd likely be headed in that direction. but alas, here we are.
btw, that val looks killer. even with the slots on it.

The Year One 17” magnums are like the 17” year one rallye’s, the backspace and sizing isn’t really very good for A-bodies. They’re basically set up for B/E bodies.
I’ve seen it done, but, you have to run smaller tires than is typically used on the wheel widths and you will have to keep your ride height stock or higher.

*grumbles*
well, this isn't looking great...
i was looking at something in the 235~245 range, how does that jive with the front end things and stuffs?
(i defer to your superior experience and granular knowledge in these such matters)

Those suckers set me back way over a grand, and that was in 2014. They were my Christmas gift to myself for the next three years.
That's the $7,500 Wonder: It was a running 225 column-auto 7.25" car when I bought it. Now it's a solid-roller W2 340, 4-speed, 4.10 Sure Grip 8.75" with SBP K-H brakes and a spring relocation--all fresh or brand new. My avatar is that car's engine. Add new floors, carpets, steering-column conversion, solid used LH front rail, custom driveshaft, SS springs, eight tires, blah blah blah (the parts list goes on forever) and I'm still into it for less than $8K including the car. That's why it's still beat, rusted, and bondoed, and it will stay that way. We made it solid enough to hurl down a dragstrip, with no thought given to looks.btw, that val looks killer. even with the slots on it.
They tell me shiny paint creates stress. I wouldn't know.
Here's a crappy picture with the drag wheels, back when the vinyl top was present:

That valiant is just about perfect in my book.

your honor, let the record reflect that the witness is being unreasonable.

Typing small won’t make it true.
The 17x8 YO magnums have a 4.5” backspace.
245/45/17’s need more like 5” of backspace (minimum!) on a 17x8 to have any real clearance to the fenders in the front.
By comparison, a set of 245/45/17’s on a 17x8 with a 4.5” backspace will stick out over a 1/2” further than the 275/35/18’s I run on 18x9’s on my Duster. And my fenders have the lips rolled flat and the whole thing is pushed out with the fender roller. My car is lowered and with the push I have a bit of clearance, but to run those YO 17x8’s you’d have to put the wheel opening well above the top of the tire to keep from rubbing.
And while that’s possible, it looks like ****, especially with the 17” wheel and shorter sidewall. The 235 saves you a few mm’s but even those are still further to the fenders than my 275’s are. Only a 225 gets close to the same spot as my 275’s, but at that point the tire will look stretched on the rim, which also looks like crap on these cars.
Now, some of that is my opinion, but in my opinion with a 17” or larger wheel you need the top of the wheel opening pretty close to level with the top of the tire. And you need a bit of shoulder on the tire, so, you want the tires measuring wheel to be about the same as the wheel width you’re gonna run. If you run the max recommended width wheel (like a 225 on a 17x8) the tire sidewall gets rounded with the stretch and looks even shorter, which makes it harder to make it look good on an old muscle car.
A friend of mine has the same model GTO as me. My GTO has the original 14" wheels, but one inch wider [ now 7" ]. 235/60 section tyre. Mates car has these horrible looking 17" wheels, small section & feels every bump in the road, like & horse & cart.
Wheels and tires are a part of your cars suspension. If you just slap a set of 17's on without making the appropriate changes to your alignment and suspension components you can absolutely end up with a car that rides like crap, even though you've likely improved its grip and potential performance. But you have to match the suspension to the new capabilities of the wheels and tires.
You would have the similar result if you put 14" rims and bias-ply's on a modern car without making changes to the alignment and suspension- it would handle and ride like crap, because that's not what the suspension was designed for.
If you make the proper improvements to your suspension the 17" wheels will improve handling without sacrificing ride quality. But that requires matching the capabilities of your suspension to your new wheels and tires and running a proper modern alignment, not factory specs for bias ply's.
