Hydraulic Lifters

1955-85 Gen 1 SBC, 1965-96 BBC Mk4 & 5

These lifters are designed to operate at higher rpm limits, when used with the correct preload. If you plan on running your engine past 5500rpm with a high lift cam, these lifters are safer to use. Same fitting range as std lifters.

These lifters are for use with hydraulic roller camshafts. There are two main types, standard as used in the original “OEM” engine, or “RETRO” for use in engines that never had a roller cam. Then there are standard, or “high rev”. For lifts over .570” or so, and rpm’s over 6000rpm, it may be safer to use the “high rev” lifters.

These lifters 'Bleed Down' below 3500 rpm, thereby reducing overlap and lift. In engines where noise is not an issue [eg: Stock Cars] a slightly wilder cam can be used, & yet still retain good power out of the corners. These lifters make a ticking noise. They are also a “high rev” lifter. Same fitting range as std lifters.

Mechanical or solid lifters are most often used for Motor Sport applications. The oil to the rocker gear is restricted, so it is common to use rockers with needle roller bearing trunnions, that require less oil. Same fitment range as std lifters.

For years, Comp Cams Super Roller Lifters have set the standard for solid roller lifter technology. With todays radical cam lobe designs & increased rpm ranges, it takes a superior roller lifter to withstand the abuse. Now with EDM oil injection technology which ensures the bearing receives a constant flow of pressurized oil.
