All Barra I6 engines are DOHC with Variable valve timing and contain 24 valves. [2] They are a development of the SOHC "Intech" I6s produced between 1998 and 2002, or the SOHC produced from 1988 to 1998, which in turn are a development of the 3.3 and 4.1 L push-rod flat-tappet I6, developed in Australia as an "Alloy Head" Crossflow in 1980, eventually in both carburetted and injected versions ...

The Ford Zephyr engine was a line of automotive OHV internal combustion engines that were designed for and unveiled with Ford of Britain's Zephyr/Zodiac and Consul models. The family included both straight-four and straight-six versions. Production began in 1951 and lasted until 1966, when it was replaced by Ford's Essex V4 and Essex V6 engines.
During its production run the Cologne V6 was offered in displacements of 1.8, 2.0, 2.3, 2.4, 2.6, 2.8, 2.9, and 4.0 litres. [1] All except the Cosworth 24v derivative and later 4.0 litre SOHC engines were pushrod overhead-valve engines, with a single camshaft between the banks.
The firing order has been changed from that shared by all previous Modular V8s (1-3-7-2-6-5-4-8) to that of the Ford Flathead V8 (1-5-4-8-6-3-7-2). [17] Compression ratio is 11.0:1, and despite having port fuel injection (as opposed to direct injection) the engine can still be run on 87 octane gasoline.
The 250 was a stroked 200, made by increasing the stroke from 3.126 to 3.91 in (79.4 to 99.3 mm). Output was 155 hp (116 kW) in the Mustang, and the 250 became the base engine in 1971. The Ford Granada and Mercury Monarch offered the 250 inline-six for the 1975–1980 model years, when it was replaced by the 200 inline-six.
