Kevin Troutman begins work on the stock cast-iron intake manifold that’s required by the rules. In OEM form, Clevelands were outfitted with a spread bore carburetor. You can purchase an adaptor to fit a square-bore Holley carb onto this manifold, but performance will suffer unless you open up the extremely small holes that lead into the plenum. Troutman uses a milling machine here, but you can get by with a hand grinder and a lot of patience.
