Building on the features that make the GenX® 255 for GM LS3 great—like 12° valve angles and relocated valves for reduced valve shrouding and improved piston-to-valve clearance—Trick Flow's GenX® 280 HIP cylinder heads withstand the abuse of high horsepower, power-adder performance demanded by today's racers and engine builders. The GenX® 280 heads list of features is long, and it starts with the HIP'd (Hot Isostatic Pressed) castings. This process significantly increases the casting's density for improved tensile and fatigue strength. It continues with industry leading airflow through CNC Competition Ported 280cc intake ports and Trick-Alloy™ powdered metal valve guides for added longevity. Manley Severe Duty intake valves and Extreme Duty Inconel exhaust valves are designed to withstand the abuse of extreme temperatures and stresses of big power adder applications. Trick Flow® by PAC Racing dual valve springs, titanium retainers, .750-inch thick deck, and 6-bolt-per-cylinder mounting pattern round out the features. Trick Flow® GenX® 280 HIP cylinder heads for GM LS3 work with all LS3 intake manifolds and LS9/LSA blower assemblies and fit all LS head gasket and engine block combinations. These cylinder heads are available fully assembled or as bare castings. Sold individually. Key features: * 280cc intake ports and 67cc combustion chambers * HIP'd casting * Accepts 3/8 in. pushrods * Powdered metal valve guides * 2.165 in. NK-844 severe duty stainless steel intake valves * 1.600 in. XH-432 extreme duty Inconel exhaust valves * .750 in. thick deck * 6-bolt configuration * Assembled heads include a Trick Flow® LS3 rocker stand

BoostLine connecting rods are designed specifically for demanding turbocharged, supercharged, and big nitrous applications. The patented, 3-pocket body forged from premium 4340 steel incorporates the best features of both the H-beam (mass/weight) and I-beam (strength) designs. This provides 60 percent more bending strength compared to common H-beam rods. Each piece is heat-treated, shot-peened, and fitted with ARP-2000 cap screws (strong, malleable, and 220,000 psi rating) before final finish machining. Keep things straight with a set of BoostLine connecting rods (also available individually). Order the connecting rods in the model recommended for your specific engine size. Features, items, and specs: * High-quality Ampco bushing material used in the small end * Pin clearance at between 9-ten-thousandths and 11-thousandths of an inch (allows engine builder to custom set wrist pin spec, should additional clearance be necessary) * All BoostLine rods are individually inspected via a coordinate measuring machine (CMM) that is used to custom-match sets of rods to incredibly tight tolerances * Each rod includes an inspection report from the Wiseco Piston quality team * Rods are completely separated by thick foam for protection from shipping damage * Each rod is vacuum-wrapped in plastic for corrosion protection * Upgraded ARP 625+ bolts (260,000 to 280,000 psi) available

COMP Cams belt drives represent the ultimate in cam timing systems, providing competition engine builders with the most accurate valvetrain components available today. These drives are designed to absorb a significant amount of crankshaft harmonics, which will affect valve motion if they reach the valvetrain. These systems require less power to operate than conventional belt drives, and are proven to be more durable than either gear or chain drives.

CP Pistons 400 Chevy 18 degree dome gas port pistons are designed for serious motor builders and are intended for use on drag racing engines. They feature gas ports in the deck of the piston to provide the top ring with extra sealing in between the compression and power stroke. These pistons include chamfered pins, wire locks, dedicated left and right hand forging, and are all balanced to +/-1 gram. With their radius dome, radius valve relief, and special design for use with backcut rings, these pistons produce the kind of power that every drag racer wants!

Built for racers and engine builders who craved the performance, Moroso racing vacuum pumps are manufactured from billet aluminum and feature a precision-machined shaft, rotor, and bearings that will withstand the rigors of racing. They work by producing high crankcase vacuum, which increases power by improving ring seal, preventing blowby, and detonation. Allowing the use of lower-tension piston rings for less friction. These positive pumps are much more consistent and effective than header-mounted evacuation systems.

Sportsman racers need reliable parts that will get them through the entire race season. Edelbrock Victor DR-17 Pro-Port raw cylinder heads are designed to give consistent performance in big block Chevys. These new-wave heads are based on the 24 degree Victor Gen II raw design, but feature 17 degree intake valve angles for improved efficiency and combustion, and a slight adjustment in location for better flow. Edelbrock uses a pressurized chamber and aerospace process called Hot Isostatic Pressing to compress castings at nearly 900 degrees F and 30,000 psi to give them nearly three times the average fatigue life, wicked strength, extreme density, and near billet aluminum consistency. DR17 Pro Port heads are cast with enough wall thickness for CNC-machining to various port dimensions, and will allow most CNC port shapes, sizes, and locations. Be ready to rumble next season with Edelbrock Victor DR-17 Pro-Port raw cylinder heads. Additional features include: * Raised intake port + 0.400 in. * Taller valve cover rails * Revised water jackets for maximum-effort port designs * Generally, seats and manganese-bronze valve guides are included, but not installed * Exhaust port location raised + 0.600 in. * Shaft rocker system required * Tall deck applications require the use of spacers ** Professional cylinder head preparation is required for use.
