Engine Block

The S62 engine block is manufactured from Alusil as aluminum alloy pressure die-casting. The cylinder walls are finished by an etching process only. 

The water cooling passageways of the block incorporate a connection in the "V" of the block for an oil/water heat exchanger.

The bore of the block is 94 mm. This along with a stroke of 89 mm gives the S62 engine a displacement of 5 liters. There is 3 mm between the cylinder bores of the engine. The "bare" block weighs approximately 71 lbs. (32 kg.)
