Dart Race Series Small Block Ford Aluminum Bare Blocks

Dart puts Ford racers in front with their Race Series small block Ford aluminum bare blocks designed just for Fords!

The highlights and features of Race Series blocks include:

* Cast 355-T6 aerospace alloy blocks for superior strength and integrity
* Siamesed cylinders with standard 4.00 in. or 4.125 in. cylinder bores, which can be safely bored to 4.165 in. diameters
* Ductile iron sleeves and extra-thick walls prevent cracking and produce excellent ring seal
* Scalloped water jackets increase coolant flow around cylinder barrels to prevent detonations, extend engine life, and produce consistent cylinder temperatures
* Four deck heights are available
* Steel 4-bolt main bearing caps are standard. Three center caps have splayed outer bolts for maximum strength; rear cap uses standard one-piece seal
* Two main bearing diameters of 2.249 in. or 2.749 in. 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 stock-type system, plus a low-restriction priority main oiling 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 gaskets leaks
* Standard camshafts and camshaft drives can be used
