Siamesed cylinders: Standard 4.00" or 4.125" cylinders can be safely bored to 4.185" diameter. Extra-thick walls prevent cracking and produce excellent ring seal.
Scalloped water jackets increase coolant flow around cylinder barrels to prevent detonation, extend engine life and produce consistent cylinder temperatures.
Four deck heights: 8.200" (302), 8.700" (stroker 302), 9.200" (351C) and 9.500" (351W) allow displacements up to 468ci. Short-deck versions fit under stock hoods while tall-deck versions are ideal for big-inch engines.
Steel four-bolt main bearing caps are standard. Three center caps have splayed outer bolts for maximum strength; rear cap uses standard onepiece seal. Sportsman blocks use 4-bolt centers and 2-bolt end main caps.
Two main bearing diameters: 302 (2.249") or 351C (2.749") allow choice of small or large
journal crankshaft.

Upgraded oiling system has a complete stocktype system plus a low-restriction priority main oiling system with front and rear external oil pump feeds.
Dual crossovers allow oil flow to be metered with restrictors for roller lifter cams and/or roller rocker arms to reduce oil flow and windage.
Reinforced head bolt bosses are blind tapped to prevent leaks and produce accurate torque readings. Extra-thick decks prevent head gasket leaks.
