Whats the largest size tire that will fit a 70 C10

[Fast 82]

Hello all, I am new to this board I just purchased a 1970 Chevy C10 with a 454 and 12 bolt rear end. I would like to know what is the largest wheel and tire combo you can fit under a stock frame. I plan on putting 2" inch drop spindles on the front. I would like the truck to have that rake look to it. I'm thinking of staggering the wheels. Any ideas would greatly be appreciated.

Thanks
