All 335 series engines shared the same {{cvt|4.38|in|sigfig=3}} bore spacing and cylinder head bolt pattern as the Small Block V8 family. There are a number of significant differences between the two engine families. The 335 series have a roughly two-inch extension cast into the front of the block which forms an integrated timing cover enclosure covered by a piece of flat steel, similar to an [[Oldsmobile V8 engine]]. This results in the 335 series engine block being heavier than the Small Block series engines'.<ref name="CC 351C"/> The 335 series use a dry intake manifold with the radiator hose connecting vertically to the cylinder block above the cam timing chain cover. Small Blocks use a wet intake manifold which routes coolant through the intake manifold via a horizontally protruding hose. The 335 uses smaller, 14mm, spark plugs and has a square-shaped eight bolt rocker cover while the small block's six-bolt rocker cover is more rounded.
