A range of 60 deg V-4 and V-6 engines with four displacements has been developed by Ford of Britain for varying vehicle application. Some of the features which make these units unique from previous light car engine design include bowl-in-piston combustion chamber cross-flow cylinder heads, individually mounted rocker arms, fixed piston pins, deep skirted cylinder block, closed crankcase ventilation system, throwaway lubricating oil filter, primary balance shaft (on the 4-cylinder version), high efficiency centrifugal type water pump, water heated intake manifolds and water temperature controlled automatic chokes. An important objective of the development and testing program, namely, minimum need for servicing and attention to parts, was also achieved.
