Competition Cams Nostalgia Plus 233/240 Hydraulic Flat Cam for Chrysler 273-360, 20-670-4.

“COMP Cams HEMI pushrod sets are a continuation of the Hi-Tech Pushrod line. These pushrods sets are engineered to provide optimal preload for specific late-model HEMI applications when using performance camshafts. Like all COMP Cams Hi-Tech Pushrods, these are a one-piece construction from .080″” wall chromemoly tubing and are cryo-treated for extended durability. In addition, they feature precision formed and reinforced ball type ends, and the whole pushrod is black oxide finished and laser etched. COMP Cams Hi-Tech Pushrod Sets are available for the 2003-08 5.7L, 2005-10 6.1L and 2009-Current 5.7L/6.4L HEMI applications.”

These grade 5 socket head bolts are zinc plated for protection and appearance. Hardened flat washers provide uniform torque & prevent galling on aluminum manifolds. Includes twelve (12) 3/8-16 x 1 inch bolts & washers.

These special Grade 8 intake manifold bolts feature a 12-point smaller-than-standard head and flange, and include special extra thick flat washers for optimum clamping pressures. They’re ideal for use where space is minimal, typical on larger runner race manifolds. These bolts and washers are bright zinc plated for protection and good looks.

The EFI fuel rails are machined for -8AN O-ring fittings with passages large enough to accommodate high fuel flow and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.

“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.”
