DART Ford Iron Eagle Blocks
Dart puts Ford racers in front with our first iron blocks designed
just for Fords. Working with leading Ford racers and engine builders,
we
designed the Iron Eagle Race Series and Sportsman small-blocks to solve
the shortcomings of production-type blocks used in high-performance
and competition applications. Dart blocks for Fords are produced on
dedicated tooling and machined on state-of-the-art CNC equipment. We
added the features that Ford racers need to build powerful and reliable
engines. Take a close look and you’ll see why Fords fly with
Dart!

Ford Iron Eagle Block Features:
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.
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 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.
Standard camshaft and camshaft drive can be used. Lifter valley of sportsman
block has bosses for production hydraulic roller lifters.
Precision CNC machining ensures consistent high quality and eliminates expensive “blueprinting.”
