The Holden EH is an automobile produced by Holden in Australia from 1963 to 1965. The EH was released in August 1963[1] replacing the Holden EJ series, and was the first Holden to incorporate the new red engine, with a seven main bearing crankshaft instead of the four main bearing crankshaft used in the grey engine. The newly released Red engine initially came in two capacities that being the 100hp 149 and the 115hp 179 cubic inch displacement. Standard issue on all models (except Premiers) was the 149 CID in either the manual or Hydramatic transmission. A lower compression 95 hp 149 was also available as an option, except on Premiers. The Premier models only received the larger 179 (HP cast block) and initially only with the Hydramatic transmission. The Hydramatic was a four-stage automatic transmission with a column shift although it effectively worked as a three-speed unit,except at full throttle.[2] The manual transmission was a 3 speed column shift with non synchromesh first gear with synchromesh only on the second and third (top) gear. The first EH with a 179 CID engine combined with a manual gearbox was called the "EH-S4", (officially EH225M-S4) and was fitted with an upgraded manual gearbox, having stronger gears than in the 149 gear box. Other upgrades included clutch and brakes and a few other minor changes. The mainstream release of the 179 engine mated to the three speed manual transmission option across all models occurred on 10 February 1964.
A total of 256,959 EH Holdens were produced and sold from 1963 to 1965, when the EH was replaced by the
