Something great just got better! Twisted Wedge 170 cylinder heads now feature updated A356-T61 machined castings previously reserved for Trick Flow's 11R series heads, including a .625" thick deck for more power-making strength. The castings' billet-like appearance seriously increases the cool factor too. Twisted Wedge 170 cylinder heads have Trick Flow's pioneering Twisted Wedge combustion chamber to reduce valve shrouding and enhance high-lift flow. The design features altered 15° intake/17° exhaust valve angles, which tightens the combustion chamber for increased compression and improved piston-to-valve clearance. That allows the use of higher lift cams with stock pistons—even with the 2.020" intake valves! CNC-profiled combustion chambers with relocated spark plugs optimize combustion efficiency, and a choice of 58cc or 61cc combustion chamber volumes allow builders to dial-in the perfect compression ratio. High-efficiency, Fast As Cast® runners and a competition level, multi-angle valve job deliver near-CNC-ported power and airflow at cast head prices. Assembled Twisted Wedge 170 cylinder heads come with top-quality stainless steel valves, bronze guides, PAC Racing valve springs, thread-in 3/8" or 7/16" rocker studs, and chromoly retainers to ensure great durability and longevity. Some Twisted Wedge 170 cylinder heads are emissions-legal under CARB E.O. #D-747-1 for 1996 and earlier Ford 289, 302, and 351W engines. Cylinder heads are available fully assembled or as bare castings. Sold individually.

COMP Cams is bringing the muscle car sound back, and it's nastier than ever! Let's face it--few things serve to grab our attention at a car show or cruise night more than a car with a thumping, high performance idle. In an ongoing quest to provide you with the performance and sound you demand, COMP Cams engineering team proudly introduces the Thumpr Series cam and lifter kits. The lobe profile and grind characteristics of these Thumpr camshafts use a combination of an early exhaust valve opening, a long exhaust duration, and a generous amount of intake and exhaust overlap to maximize the rough-idling characteristics of the cams. This gives you a seriously aggressive exhaust note without negatively impacting the power output or streetability of the engine. Thumpr camshafts are available in different grind profiles; each one will produce a rough, racy exhaust note and impressive amounts of horsepower and torque within a different rpm range. Thumpr Series cam and lifter kits deliver a substantial power increase over an identical hydraulic flat tappet grind without sacrificing reliability or ease of maintenance.

No longer will fans of the small block Chevy have to choose between vintage looks or modern cylinder head power—Trick Flow® DHC™ 175 cylinder heads give you both! Made from premium grade, lightweight A356-T61 aluminum, DHC™ 175 heads feature the exterior styling and straight spark plug holes that deliver the nostalgic appearance of the original factory performance 186, 291,461,462 "double hump" or "camel back" castings that customers want. To keep with the vintage design, the heads are available with 69' later or without 68' earlier accessory bolt holes cast into them. 60cc CNC-profiled combustion chambers combined with a state of the art valve job and CNC blended bowl work under the valves and small cross-section intake runners promote low-rpm torque increases and boost high-rpm horsepower. The runners are finished with Trick Flow's® superior Fast As Cast® process that precisely duplicates the runner profile and performance levels of fully CNC-ported heads without the added machining cost. Ductile iron valve seats for use with unleaded fuel, stainless steel valves, bronze alloy valve guides, multi-angle valve seat machining, and decks and walls cast extra thick for increased casting strength and to provide extra room for porting round out the features. Trick Flow® DHC™ 175 cylinder heads are available fully assembled or as bare castings. Sold individually.

Summit Racing™ Forged Pro Pistons brings modern engine piston technology to older engine platforms at the great value. Why use an antiquated piston designed fifty years ago in your new build? A great piston starts with a great forging. Forged Pro piston forgings are stronger AND lighter. This makes more power AND takes stress off the crank, rods and block at higher rpm. It also saves money balancing a crank when heavy metal is not required. Forged Pro pistons are designed around ultra-modern Nitride Steel top ring packs and Summit GP Gas Ported variants. Less friction results in more power and less bore wear. Superior machining results in less blowby for less oil consumption and longer life is the result. Better rings are great horsepower per dollar! Most old production engines were designed to run on 87 octane in heavy vehicles. If you're building a performance engine, chances are you're running it on 91+ octane and you might as well add a little pop. Forged Pro pistons yield an extra 1/2 point of compression in most instances. This is free power from idle on up for the life of the engine! Forged Pro pistons have extra thick ring lands for moderate boost and nitrous. Special care has been taken to deburr critical areas for more strength and less chance of detonation. Special skirt profiles are designed to run at tighter clearances than other forged pistons for less piston rock. This helps them make more power, run quieter and last longer than other forged pistons. Make your build run with the best of them!
