March Performance Chevy big block serpentine conversion kits simply bolt onto the front of any big block Chevy heads. Depending on the kit you choose, the alternator, A/C, and optional power steering will be either outward or mid-mounted. These pulleys are precision CNC-machined from solid billet 6061 T-6 aluminum to fit perfectly and handle high-torque and vibration. They are then clear powdercoated to eliminate polishing in those hard-to-reach places. These pulleys will not fracture like common cast pulleys, since they have high-tensile strength for much longer wear. The street rod ratio increases water flow and fan speed, which helps during critical low-speed driving. The kits are available with performance pulleys for increased horsepower, high water flow ratios for increased cooling, or mid-performance ratios for a combination of both.

COMP Cams Sportsman solid roller lifters feature premium-quality, high-value components designed for sportsman and professional racing, along with high-end street machines. They're available in both needle-bearing and bushing configurations. Each design features two pressurized EDM oil feeds, as well as an edge-orifice feed to the wheel. This delivers a more reliable oil feed than most competing options. COMP Cams Sportsman solid roller lifters are also designed with a shallower oil band than competitors' versions for increased strength and rigidity, while internal machining helps to reduce weight. The body utilizes a skirted wheel that strengthens the lifter ears, and the skirt also provides more contact area with the lifter bore for further lifter stabilization. In addition, staked axles eliminate clips and provide robust axle retention. This feature increases the stiffness of the lifter ears and helps to prevent the ears from spreading. The COMP Cams Sportsman solid roller lifters are built from 8620 premium steel for increased strength and wear resistance and they feature a captured, stainless steel link bar design. The lifters also utilize a tapered and slotted link bar tower for reduced weight and improved aesthetics. Choose the size and options tailored for your engine application.

Trick Flow® Super 23® 175 cylinder heads deliver performance that far exceeds the power capabilities of factory heads on 283-350 c.i.d. small block Chevy engines. It starts with the small cross section Fast as Cast® runners. They promote excellent port velocity for increased low end torque and have a profile that provides excellent flow for making high RPM horsepower on small bore engines. Modern CNC-profiled chambers promote combustion efficiency to maximize power with less ignition timing, reducing the potential for detonation. The result is more power and torque, better drivability, and greater throttle response from your street performance engine. The features don't end there. Trick Flow® Super 23® 175 cylinder heads have improved A356-T61 castings with 3/4" thick decks for added strength and durability. They also have a competition multi-angle valve job, angled spark plugs, and raised valve cover rails for improved rocker clearance and less potential for oil leaks. Heads are available assembled with premium components including stainless steel valves, bronze guides, 7° machined locks, chromoly retainers, and your choice of PAC Racing valve springs for flat tappet or hydraulic roller cams. Trick Flow® Super 23® 175 heads accept most original accessories. They are emissions-legal under CARB E.O. #D-747-1 for 1995 and earlier GM vehicles with Chevy 262–350 engines. Cylinder heads are available fully assembled or as bare castings. Sold individually.
