Thanks for the compliment. I agree that's too nice of a car to cut up, same reason I won't tub mine. If I wanted a bigger tire I would get a different car. I think you'll be able to get a 255 drag radial in there, and you're 3.55 will be fine with the stroker.
Don't be afraid to go the cheap route like I did and have one leaf added to the front segment of each spring, only $50 per side. It strengthens the front segment just enough that you don't need a traction device or a pinion snubber. I did have to add one inch lowering blocks since it raised the car up some but that's no big deal.
Good luck with it!
I also added rear disc brakes to my 8.75 with a very affordable bolt-in kit from Right Stuff Detailing, I bought the kit from Summit Racing. Part number MDCRDM1.
