Saying that 3rd gen f-body suspension isnt any good is far from true... The current world record holder on drag radials (high 7's) is a 3rd gen with stock style suspension. I'd say save your cash do some smart suspension upgrades and you'll be fine on stock style suspension with a 10-11.50" wide tire. Theres no reason you couldnt put the car on the back bumper with it.

406, 12:1 (or more) compression
i had planned on a stout compression ratio, but hadn't thought 12:1. of course, it's possible to do 14:1, but then i'd have to run 112 octane (or higher)
ported Dart Pro 1 230cc's (or similar)
dart makes a solid product, and i am fairly certain i will stay with them. the pro1s are a decent head, as well. just out of curiosity, would you go with their stock setup, or would you get bare heads and outfit them yourself? and if you would do it yourself, what would you stuf them with?
Solid roller cam with 260'ish duration @ 050, .600+ lift
i knew it was going to be solid roller. does a company make a cam that size, or would i have to have it custom ground? what roller rockers would you do it with? 1.7:1, or would 1.65:1 be enough? also, would a single profile cam work (same height intake/exhaust) or would it have to be a dual? and which would be bigger, the intake or exhaust?
Super Victor intake, 950+cfm carb (why not a Dominator?)
funny thing is, i was actually thinking about a high rise tunnel ram with twin 650s. the thing is, most people don't do the carb math. 700cfm is fine for the RPM i would be at most of the time, >5000, and anything bigger would most likely be a waste of cfm. if you see above, i only listed "carb and intake".
when you say "stock style suspension" what exactly are you saying? the torque arm with adjustable shocks and boxed control arms? this is what i consider a major overhaul, and the idea of a completely adjustable suspension (via the four-link) just wins out in my mind versus a "stock style suspension". i dunno. i'd like to see this car that you're talking about. i did a search and came up empty.
