4.7 officially gone (corrected)

by David Zatz on

4.7 engine

As Allpar predicted last year, Chrysler ended production of the 4.7 liter V8 engine last week at the Mack Avenue plant. The engine, dubbed Corsair during development and officially named Next Generation V8 when launched, was Chrysler’s first truly new V-8 since the 1960s. It had better power and gas mileage than the Magnum 318 V8 it replaced; a new truck V6,the 3.7, was based on it, replacing the 3.9.  The engine was used in Jeeps and Rams alike.

Refinements included significant revisions to the induction system, reduced reciprocating mass via a lightweight piston/rod assembly, reduced accessory drive speed, and electronic throttle control. A midlife upgrade provided a dramatic increase in power, to 302 hp.  Full details are on our 4.7 engine page.

Chrysler has announced that the Mack I plant will produce Pentastar V6 engines.
