The 356 engine introduced for the 1940 model year was the first Packard automotive engine with hydraulic lifters, though the V12 introduced in 1932 used a hydraulic device to take up valve stem clearance, though it was not a hydraulic lifter in the conventional sense. Postwar they were standard in the 9-main bearing version of the 327 as introduced in 1951 as the replacement for the prior senior 356 engine. Hydraulic lifters also became available (not necessarily standard equipment) in the 288 and 327 starting in the 22nd Series. These lifters in the L8 engines were all the Wilcox-Rich design, also used by other makers.
