First a little bit of insight to the planned build:
-frame off resto
-Porterbuilt pro-touring front/rear coilover DM
-C6 ZO6 brakes all around (looking at boris' kit)
-Either a wet sump LS7 or 427 LS3 Stroker
-TCI 6x 6 speed (modded 4L80e) with electronic paddle shifters (when not using the paddles it works as a regular 4spd auto controlled on the column shifter).
-Moser built rear end (true-trac, 3.73's, 33 spline
What I am trying to do is mimic the paint scheme of my ZO6. I found that if I use the ZO6 brakes and stay with the corvette bolt pattern I can use the same wheels that I have on my vette. They come in sizes from 18-20" and range from 9.5 to 12" width. I am having trouble trying to decipher which wheels will fit under the step side stock fender with out doing a mini tub. They offer a big range of offsets which is great. Ideally I would like to do a 20x12 on the rear and 20x9.5 on the front. What size tire would I have to run to fit a 12" wide wheel? I would like to have as much sidewall as I can fit. If worse comes to worse I can run a 20x10 rear and front if necessary. Here is a link to the wheel specs (they will be the deep concave): http://www.forgestar.com/v2/wheelscf5.php

Are you asking re: size wheels/tires you can run on an unmodified wheel housing and tub on a 1966 stepside?
If you are going to lower the rear any significant amount--and even if you do not--you will run into a limited space/width available for wider wheels/tires. With stock fenders and tubs, 7.5" to 8" will be about maximum width that will fit underneath. Even using 8 inch pickup/suburban/van/4wd-type rally wheels, they will rub with any decent size tires, as body sinks or sways either way, on the top sides of tire. There just is inadequate room--side to side--for a wider wheel/tire combo.
Possibly the simplest way to run wider wheels/tires is to either buy widened fenders(available only in fiberglas, based on what I found), or by widening the existing fenders; end result looks same either way you go. I, personally prefer the idea of widened fenders over widened tubs with the necessary underneath frame mods that must accompany them. YMMV.
