Stock what? Stock wheels, X Radial tires? Brand new bushings all around? Un-worn springs and struts? New hubs? Stock is a relative term. The DeVille (especially the DTS) was capable of out-turning many cars of its time and with suspension modifications, has been known to beat many newer cars in the twisties. But it doesn't matter if your suspension components are worn because one bad apple can ruin the whole barrel.

Ceramic throttle body won't help, but the bottom of the intake manifold will repell heat, allowing more head to stay in the block. like I said, been done for a while.

Actually the point of coating the underside of the intake manifold is not to keep more heat in the block, it's to stop the heat soak into the manifold for cooler intake charges. Which still won't net you any noticeable horsepower on a 4.9. You may as well increase the intake valve size and increase the compression ratio while you're at it, because those won't do shit either. All cookie, no cream. Or maybe all cream and no cookie.

So you're saying your deville has a curb weight of less than 3100 lbs? There must be nothing left of that interior. Wouldn't imagine it would be that comfortable in driving.

3,121lbs to be precise. Comfort is a relative term. I find comfort in knowing my car is faster than the next guy's.
I also just updated my cardomain to reflect the car's current specs, because I get around to updating it about twice a year.
