I would KILL to have this engine. 

OS Giken TC24 dual cam cylinder head

L28 block bored and stroked out to 3.2 liters

Equal length headerers

Weber carbs

Gear driven timing

420 HP at 9,000 RPM

293 ft/lbs at 8,000 RPM

Redline 10,000 RPM


OS Giken TC24-B1

Original design — conversion from belt to gear-only camshaft drive system. Engine response and timing accuracy are increased and the sound of the engine becomes subtly more exotic. This changes the feel of the engine completely. This level of development to the old L-series has always impressed me as there are no power gains, only an improvement in the driver/car connection.
