Distributorless ignition system. Electric fuel pump replaces a mechanical fuel pump. Cast aluminum oil pan replaces a stamped steel oil pan. Alternator is solid-mounted which eliminates the requirement to tension the belt with an adjustment arm. The alternator is driven by a poly-vee belt with an automatic tensioner.
Water pump is new cast aluminum pump.
Reduced vibration and noise. Longer connecting rods and lighter pistons reduce shaking forces and a cast aluminum oil pan absorbs internal noise better. Better fuel economy. Internal friction is reduced by elimination of the auxiliary drive shaft, the use of low tension piston rings, and low friction roller type camshaft followers. Roller cam followers extend the camshaft service life, tougher pistons with low tension rings reduce cylinder and ring wear.
