[BR3W CITY]

I didn't see anywhere in the post about HOW wide you want to go? On my stock width 71 12-bolt, with a tubbed bed, stock width framerails/66 rear suspension; I can fit a 325/50/15 on a 12" wide rim. I could fit about 3/4" more tire if I roll the edges on the stepside fenders.

I consider that fairly wide, much larger and its what is so eloquently considered a "big-tire car". Even with 550hp, it doesn't really justify the cost, weight, and drag those tires have. Thats just my opinion, but I know plenty of small-tire cars in the 9's.
