Wicked Racing and Dart Blocks
Designed for hard core racing, the Dart Iron Eagle Ford block addresses all the weakness of factory castings. Dart blocks are cast from premium, high strength iron with extra thick cylinder walls and decks. The main webs are beefed up and fitted with steel 4 bolt main caps for superior durability.
Every Dart block is individually qualified to ensure maximum thickness where you need it most, every time. Dart blocks are fully CNC machined and virtually ready to assemble with off the shelf components.
DART Iron Eagle Ford Blocks feature:
Siamesed cylinders: Standard 4.000″ or 4.125″ cylinders can be safely bored to 4.165″ diameter. Ductile iron sleeves and extra thick walls prevent cracking and produce excellent ring seal
Multiple deck heights allow for increased displacements of up to 468 cubic inches
Scalloped outer water jacket walls improve coolant flow around the cylinder barrels to prevent detonation, extend engine life and produce consistent cylinder temperatures
4 bolt billet steel main caps. Three center caps have splayed outer bolts for extra strength; rear cap uses standard one piece seal
Two main bearing diameters 302 (2.249″) or 351C (2.749″) allow choice of small or large journal camshaft
Stock components make Dart blocks a direct replacement for most production small blocks. Provisions for stock motor mounts, accessory drives, smog pumps, starter brackets, oil pans and pumps
Upgraded oiling system has a complete stock type 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 rocker roller 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
Standard camshaft and camshaft drive can be used
