 The combustion chamber volume...  The combustion chamber volume of the Indy heads is 170cc, and the valves measure 2.400 inches on the intake side and 1.940 inches on the exhaust side.  The finished engine assembly...  The finished engine assembly is dressed with the plugs, wires and other accessories that are typical of a World Products crate engine. It's an impressive sight, particularly when you understand that it weighs less than 600 pounds-about the same as a similarly dressed iron small-block engine.  The intake manifold required...  The intake manifold required some minor modifications to accommodate a 4500-series carburetor. World Products pays close attention to the top section of the intake manifold, ensuring optimal airflow.  An MSD Pro Billet distributor...  An MSD Pro Billet distributor is slipped into the cylinder block. A bronze intermediate shaft bushing is part of the basic cylinder-block setup.  Our engine was put through...  Our engine was put through its paces on World's dynamometer, where it laid down some impressive numbers. Horsepower pegged at 776.8 at 7,100 rpm, while torque reached 641.7 lb.-ft. at 5,800. For a big-displacement Hemi, this one revs willingly and should be a lot of fun in a strip-prepped A- or B-Body.  An Eagle 4340-forged steel,...  An Eagle 4340-forged steel, internally-balanced crankshaft is used. It is a sturdy piece that works well at resisting the flex that can occur with long-stroke engines. Its 4.500-inch stroke matches the block's bore diameter, making this Hemi a "square" engine.
