Let's begin our discussion with the Fairlane V-8 series, sometimes called the short-deck engines. Originally offered in a 221 displacement and then in the 260 size, these two early displacements of the engine are fine in original applications, but the smaller bore size make most modern equipment not transferable. These two early displacements of the Fairlane V-8 have a five-bolt bellhousing pattern. The more popular 289-302 engines have a six-bolt bellhousing pattern. The engine in this photo, while it has a non-stock distributor from Davis Unified Ignition, shows a six-bolt valve cover pattern and horizontal orientation of the water outlet, which is part of the intake manifold. These characteristics are also shared by the 351 Windsor engine. The valve covers used are identical and the exterior architecture is very similar. The dimensions of an assembled 289 or 302 engine are 29Lx24Wx27 1/2H.
