Absolute specimen. Rare H1 Alpha Open Top Collector's Car, meticulously maintained, upgraded 6-speed transmission. The &quot;Alpha&quot; was a re-engineered H1 equipped with GM's 6.6 L Duramax Diesel and 5-speed Allison transmission. This replaced the previous GM 6.5 L diesel engine. To fit into the H1 engine bay, 23 engine component changes were incorporated as well as a 2.0 in (51 mm) body lift to accommodate the taller engine and its turbo housing (a prior 0.5 in (13 mm) lift had been done for MY96 to accommodate the turbo on the 6.5 L engine). The 8th digit of the VIN is 3, setting this version of the 6.6L Duramax apart from the versions used in pickup trucks.[12] The GMT560 engine output was 300 hp (220 kW) and 520 lbft (705 Nm) of torque. The engine was equipped with cooled exhaust gas recirculation and an internal engine oil cooler, thus, requiring a 40% heat rejection increase to engine coolant. Because space was limited between the air-lift brackets that protruded from the hood, the fan system was modified by putting it directly under the cool pack and driving it through a special gearbox directly off the crankshaft damper pulley. Several other cooling system modifications were required to assist with cold starting from 30 F (34 C). Must see to appreciate.
