This engine was redesigned as an OHV for the 1956 model year, [3] but the flathead version reemerged in 1958 as the economy engine for the "new" Rambler American and remained available through 1965. [3] American Motors introduced a die-cast aluminum block version of the OHV 195.6 cu in (3.2 L) engine in 1961 and produced it through 1964. [4]
The gerotor-type oil pump was located at the bottom-rear of the engine, and provided oil to both the crankshaft main bearings and the cylinder heads (via the lifters and pushrods, as opposed to a drilled passage on LA engines). Chrysler's engineers also redesigned the oil seals on the crankshaft to improve anti-leak seal performance.
1993–97 3.5 L engines are a non-interference design, in which the valves will not collide with the pistons in the event of a timing belt failure. The 1998–2001 3.2 L, the 1998–2010 3.5 L, and the 2007–2011 4.0 L engines are interference designs.
The Northstar engine is a family of high-performance 90° V engines produced by General Motors between 1993 and 2011. Regarded as GM's most technically complex engine, the original double overhead cam, four valve per cylinder, aluminum block/aluminum head V8 design was developed by Oldsmobile R&D, [citation needed] but is most associated with Cadillac's Northstar series.
Split crankshaft pins permit even firing intervals. Versions of the engine used in front-engine, front-wheel-drive layouts (FWD) have a different bellhousing pattern than those use in front-engine, rear-wheel-drive layouts (RWD). In 1977 Ford foresaw the need to develop a new engine for use in mid-size cars and light trucks in the 1980s.
The oil pump, distributor, and fuel pump were driven by an external jackshaft powered by a rubber timing belt nestled within an aluminum housing bolted to the right side of the block. The head had a single port face with both exhaust and intake valves on the left side and valve stems strongly tilted towards the left.
