“Competition Cams Valve Spring Kit, For Ls 1.310″” Beehive 1 Kt, 26915CS-KIT. ”

“This Beehive Valve Spring Kit for LS engines is designed for hydraulic roller cams and includes carefully matched Beehive Springs, steel retainers, locks, seals and spring seats. With a .625″” maximum lift, these Beehive Valve Springs deliver increased valve train stability and a much lighter valve train. This is achieved with less spring pressure for better valve control and reduced weight of both the spring and retainer. The unique Beehive shape handles valve train stress more efficiently to eliminate damaging harmonics and increases high RPM horsepower and durability. The oval/multi-arc wire shape places the maximum area of the wire at the point of highest stress to handle valve train stress more efficiently and allow better heat dissipation for longer life.Kit Includes:26918-16 Beehive Valve Springs774-16 Steel Retainers623-16 7° Steel Valve Locks511-16 Valve Seals4705-16 Spring Seats”

COMP Cams Hydraulic Roller Lifters are a performance upgrade for stock hydraulic roller lifters or retro-fit hydraulic roller lifters for non-roller blocks. The roller wheel decreases friction and increases longevity when compared to flat tappet lifters. Hydraulic roller lifters can handle much more aggressive cam profiles than flat tappets unlocking performance potential.

Edelbrock part No: 9738 Performer-Plus lifter set for S/B & B/B Chevy is designed for use with Edelbrock Performer-Plus or equivalent camshafts. Sold in complete sets.

Competition Cams Camshaft Lock Plate w/ Bolts for GM LS GEN III/IV with 3 Bolt Camshaft, 5461.

Featuring a quicker valve opening, the Xtreme Energy camshaft profile provides increased responsiveness and more area under the lift curve than older, slower grinds. Designed to increase performance without sacrificing drivability and creature comforts, the Xtreme Energy grind family offers gains in torque and horsepower while still delivering adequate vacuum for power brakes and other vacuum dependent accessories. Xtreme Energy camshafts work great in carbureted applications, but offer the best performance with aftermarket intake manifolds, lower gear ratios, headers and free flowing exhaust.

The newest cam technology is used in COMP Cams Xtreme Energy camshafts to deliver optimal performance. There is an Xtreme Energy cam for every use, including off-roading, towing, and street performance. These cams outperform comparable cams from other manufacturers in terms of throttle responsiveness and top-end horsepower because to their aggressive lobe profile, which also increases engine vacuum. There are hundreds of versions that can be installed on cars made between 1955 and the present. Choose the cam made specifically for your use case.
