LS7_Lifter.jpg  LS7 RACING LIFTERS $280 (7000rpm) * 88958689
GM Performance hydraulic roller lifter set for high performance applications. This new hydraulic roller lifter was developed by GM Racing and contains lightweight internal components and precision oil metering for increased valvetrain stability at high RPM’s. This part number is a set of 16-lifters.
This new lifter will work in all LS- engine applications and is specifically suited for race cams and high RPM applications. They can also be used as an upgrade for stock lifters and are suitable for street applications. These lifters were developed for the CTSV Cadillac Race Team that used the “short stroke” LS7 style engines that raced in the Grand Am Cup Series during 2005. If you recall these engines were built using the LS7 block, LS7heads, and LS7 intake but the sanctioning body required the teams to meet the 5.7-liter engine size of 346ci. There were several different combinations tried but most of these engines used a stroke of approximately 3.200”. The demand to make race winning horsepower with a short stroke guarantees the unavoidable element of high RPM’s.
Initial testing, before these new lifters were developed, showed a definite valvetrain stability problem above 7000-rpm’s. Several remedies were tried, but in the end it was determined that the lifter had the biggest contribution to the RPM limit. This new lifter has internal changes made to the hydraulic components which resulted in a significant RPM increase. After installing the new lifters, these engines were now making power at 8000-rpm and they regularly saw 8500-rpm’s without any problems! WOW! The CTSV dominated the first races, not only did the sanctioning body enforce an RPM limit on the short stoke Caddies but they eventually implemented more restrictions to limit the horsepower on these LS7 equipped 346ci engines.
As a reminder, hydraulic roller cam valvetrain stability is a function of many different variables; camshaft design (ramp acceleration), pushrods, valve springs, rocker ratios, spring pressures, valve weight, the weight of all valvetrain components, oil pressure, RPM, etc. It is imperative that you have sufficient spring pressures, quality push rods and lifters, proper lash adjustment, and the lightest valvetrain components you can afford to maintain accurate stability at high RPM’s. Match your components to meet your RPM range! We recommend a preload setting of 0.060” (cold) with these lifters, in most cases with adjustable rockers this is usually somewhere between 1-full turn and 1-1/2 from the “Zero-Lash” point. This is the same preload as a stock lifter

Power output depends on cam duration.
Long duration cams make more bhp, but have a rougher idle and less vacuum.
Anything above In. 236 @ .050" is short on vacuum for power brakes.
Shorter duration cam increase torque in the 2000rpm range.                    See Examples
