These engines were fitted to all Australian designed Holdens of the same years, and the four-cylinder Starfire notably also found its way into the Toyota Corona (XT130).

The Grey motor is a different engine from the others, while the Red, Blue, Black, and even the Starfire are all inter-related with many common parts and castings.

This overhead valve engine was first fitted to the Holden 48-215 (and variants) and mated to a three-speed column change gearbox.

It developed 76 brake horsepower (57 kW) at 4200 rpm and 120lb.ft (162N.m) at 1400rpm, providing superior performance to the competing four-cylinder Austin, Morris, Vauxhall and Ford of Britain vehicles.

The inlets were fed by a single-barrel Stromberg carburettor in common and fitted with a traditional Kettering ignition by coil and distributor.

[citation needed] The prefix "U" was introduced for motors with the original electricals as fitted to the FJ utility and panel van models, which ended in February and May 1957 respectively.

The capacity markings cast in raised numbers, (149 or 179) located on the side of the block behind the generator/alternator, began in January 1965 in readiness for the HD model due for release in February 1965.

[4] The blue motor was a development of the earlier red engine, and incorporated several improvements; the biggest of these changes was the complete redesign of the cylinder head.

Pending emission standards and the requirement for unleaded fuel made it difficult to re-engineer the Australian engine.

[8] This 1.9-litre (1,892 cc) powerplant, known as the Starfire engine, was effectively Holden's existing 2.85-litre 173 cu in straight-six with two cylinders removed.

[citation needed] Peak power output for the Starfire was 58 kW (78 hp), with a 17.5 second acceleration time from 0–100 kilometres (0–62 mi) in the VC Commodore.

[9] This variant's performance meant the need to push the engine hard leading to fuel consumption similar to the straight-sixes.

This engine was replaced in the Australian market by the Camira's OHC Camtech unit, however, it continued to be used until 1986 in New Zealand, where it was used to power four-cylinder versions of the VK Commodore.

[10] Engines installed in Toyotas received some slight differences in the form of a unique camshaft, manifold, and carburettor.
