I have put together a 425 Nailhead and installed it in a 1952 Buick woodie station wagon. The block is a 1966. The intake is a 1963. The heads are 1959. I have the engine running and it was balanced. The cam is a mild version for torque. I bought a new Edelbrock 800 CFM carburetor. It has 150 pounds compression, 18 inches vacuum. With 3:08 reared gears it will spin one tire just by stepping on the gas. I don't know of any Buick Nailheads around here to compare it too. I do not like the way it idles. I have read that Buick cams are pretty aggressive. Does that mean they do not idle smooth? I can screw the idle mixture screws all the way in and the engine continues to run. I have exchanged carburetors and the idle mixture screws act the same. I have removed the intake manifold and inspected it. I have inspected the carburetor gasket to make sure there are no leaks. I have sprayed starter fluid around everywhere and no sign of a leak. Any one have a idea?
