That frame sounds like a monster thing to put under an Olds. Rack and Pinion steering was another thing i was looking into which it has. The price is definately a huge factor, considering the IRS is another 9 Gs. But the IRS it has is plenty strong. At least they say. haha But the Jaguar IRS sounds like a cool route to go as well. I was unaware that they put a Dana 44 under those things. Definately something to think about. The thing that I like about that frame though is how much easier it would make the job. Getting a clean slate minus the body is aready half the battle over, provided one has the cash. Money isn't a big nusiance considering I'm basicly going to be housed, fed, and medicaly taken care of by the U.S. government for the next 6-20 years. Haven't decided yet. haha There will be plenty of money to save. But I'd definately go with the 3.25 ratio on the differential for max top speed. If possible, just go balls out on a build like this, ground up, get the rotisserie, get out the sandblaster, the oxy-acetelyne. I'm going to order the parts while I'm away, and when I get my leave for 4 weeks a year, spend that time workin on the beast. haha That's the plan at least. There's a lot of options to consider. Plenty of nights to ponder ideas.
