QUICK INFO >>><br />
Dart’s Race Series Aluminum big block is based on<br />
the Chevrolet big block V8 design, with added features<br />
like increased deck height and a raised cam<br />
location.<br />
The camshaft is raised .400" above the stock<br />
location to increase clearance for the connecting<br />
rods and crankshaft counterweights.<br />
The main oil gallery is located alongside the<br />
camshaft tunnel to eliminate interference with<br />
the crank assembly.<br />
Advanced engineering makes Dart Aluminum<br />
big blocks the choice for serious competition.<br />
FEATURES<br />
• Premium alloy: Dart Aluminum blocks are cast from RMR Cast Aluminum<br />
alloy for superior strength and integrity.<br />
• Standard 9.800” or 10.200” deck heights/options to 10.400”.<br />
• Raised camshaft location +.400” clears stroker crankshafts.<br />
• Ductile Iron sleeves with extra thick cylinder walls promote excellent ring seal.<br />
• Reinforcing ribs strengthen the lifter valley and bell housing flange.<br />
• Inboard valley head stud bosses improve head gasket sealing.<br />
• Priority main oiling system delivers oil directly to the crankshaft bearings to<br />
enhance reliability at high engine speeds.<br />
• With or without distributor provision.<br />
• Steel 4-bolt main caps or Ductile Iron and optional Aluminum caps. Splayed<br />
outer bolts for extra strength.<br />
