Essential Cadillac Eldorado Performance Engines

Competition Cams – Competition Cams Valve Springs, 26918-16 (Part No.26918-16)

Competition Cams Valve Springs, 26918-16

from

$288.99
“With a .625″” maximum lift, these Beehive Valve Springs were designed for hydraulic roller cams in LS1, LS2 and LS6 engines. COMP Cams 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. Because of the unique Beehive design, the valve train can handle more RPM and more aggressive cam profiles.”

Competition Cams – Competition Cams Valve Seals, 503-16 (Part No.503-16)

Competition Cams Valve Seals, 503-16

from

$223.99
COMP Cams offers a complete line of valve stem seals, from the umbrella seals to the positive-stop Teflon seal. These seals are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The umbrella seal is normally used when a larger-than-stock diameter spring is used, in the case of a double spring, the positive-stop Teflon seal is used. The umbrella seals require no machining, but with the Teflon seal it is necessary to disassemble the heads and machine the top of the guide with a special .530 diameter cutter. Whenever you are planning an engine overhaul or a cam change, don’t forget the valve seals.
