The 335 series V8s were overhead valve pushrod V8 engines that used a short-skirt engine block. This family of engines incorporated design features used on the 385 big-block series, including the canted valve layout, the valve train design, and thin-wall casting technology. All 335 series V8s had free breathing, large-port canted valve heads with a rugged engine block. These engines use a shallow poly angle combustion chamber rather than the wedge style used on the Windsor V8 engines. The 335 engines use large main-bearing caps, with four-bolt attachment on some versions. All 335 series are cast with provisions for four-bolt main bearing caps to be added through modification.
