Lincoln Versallies is what you want if you want a Ford 9", because it comes stock with a 5x5 bolt pattern, and is disc braked. a few mods to an 8.5" 10 bolt out of a 9C1 Caprice, and it could be nearly as strong. as with the Lincoln 9", its factory 5x5 and disc braked.
as for the Burb idea... i think it would be better suited for a 2wd K5. anybody who has ever driven an insanely short wheelbase drag car (think Vega/Monza, Pinto, etc) will know how much weight transfer can effect things. when you want to hook up and go fast, a shorter wheelbase is definitely a tool to use to your advantage.
personally, i'd go for a lowered 2wd K5 (could start with a 4wd, then add a 2wd front crossmember, its all bolt in) glass everywhere you can get it, cage it, hard springs up front, soft in the rear, with a set of CalTracs (
www.calvertracing.com). strip out all the power options, and the interior. i have seen .060" aluminum used to replace the stock interior panels, and it still looks pretty good.
i was going to build a C10 to do basically the same thing. i was going to go a little further than most. lightening holes in the dash under the dashpad, behind the door panels, hell even in the window regulators you can shed some weight. want to keep it stealthy? keep the outer heater box and even the hoses. drill and tap the fittings at the intake and the water pump to accept pipe plugs, the hoses will still be there, but wont weigh near as much as ones full of water. i cut a heater core down to retain them to the firewall. the blower motor can be gutted to appear stock. EGR valves, hot air chokes, etc can also be gutted blocked off with pop cans. the above mentioned black primer will hide the fiberglass nicely. no chrome under the hood, maybe even a light coat of oil on the outside of the engine, so it doesnt look messed with. i've seen a stock air cleaner used to hide a plate nitrous system. no blingy red and blue anodized fittings, paint em black, and cover with wire loom. as for the ignition system, the hole created under the dash by the removal of the heater/AC system is a perfect candidate for ignition system mounting, Borg Warner plug wires (black, look like nothing, but are the best out there).
thanks alot, now i want to build the sleeper truck that i never finished.
