It's $899.99. Lots of AN plumbing for the fuel system (I suppose) is included and that stuff ain't cheap!
I'm thinking this would be a perfect setup for a 225 slant six utilizing a PISHTA-design, bolt-on turbo mount. Instant 250hp turbo slant six on pump gas, with a waste-gate controlled 10 pounds of boost. You wouldn't even have to pull the head off; just bolt on a Super Six 2bbl intake manifold and a blow-thru modified 500cfm Holley 2bbl carb. If you opted for a water-alky injector, you could probably make a pump-gas friendly, 300 hp.
That would put a 3,200-pound A Body solidly in the 12's... with the right tires.
