CLINTON TOWNSHIP, Mich. – Katech now offers its popular cast aluminum, CNC-machined valve cover design for the Gen V “LT” small-block V-8 engine, as well as complementing coil relocation brackets, to enhance the underhood appearance of 2014+ Corvettes, 2016+ Camaros and 2014+ Chevrolet and GMC full-size trucks and SUVs.

More than stylish, the raised design of the covers provides clearance for high-performance valvetrain components such as larger valve springs and rocker arms. They are also designed with easy access to the cover fasteners without removal of the ignition coils.

“Katech’s Gen V valve covers build on the functional design and style introduced with our original LS-series covers,” said Jason Harding, director of aftermarket operations, Katech. “Gen V valve covers feature an edgier design with sharper corners, mimicking the design evolution from the more rounded C6 Corvette to the well-defined lines of the C7 Corvette.”

The new Gen V covers, which list for $429.99, are CNC-machined in-house at Katech and are offered for wet-sump (with fill hole and Mobil 1 oil fill cap) and dry-sump (no oil fill provision) applications, and include the fasteners, gaskets and necessary fittings. They are also offered with slots designed to accept machined inserts (sold separately). Katech-logo inserts are offered and customized inserts are also available.

Additionally, custom powder coating is offered, allowing customers to tailor the color of the covers to the paint scheme of their vehicle.

The available coil relocation kit ($229.99) enables the coil pack to be mounted above the valve cover, for a custom appearance that puts the gorgeous valve covers on full display. Katech offers MSD plug wires ($55) for a tailored fit with the relocated coils and a spark plug boot insulator sock ($6.99/each) for added heat protection.

Katech’s new valve covers join a growing list of engine parts and engine performance packages for the Gen V LT series, as well as complete engines, including the 700 hp, naturally-aspirated Street Attack 427 engine.

The Katech 550 Engine Package













Tested Performance, Proven Power


Going to the track on a budget but can’t afford nor want to sacrifice the power plant of your race day car? No need to worry because Katech has you and your team covered. The Katech Engineering and Motorsports team have been hard at work designing, developing and testing the newest addition to Katech’s engine package lineup and are proud to present the new “Katech 550 Engine Package.”


The Katech 550 Engine Package goes far beyond the developed and precisely tweaked 550hp 6.2L LS3 and delivers more than just an assembled engine to its new owner. The 550 Engine package brings only what a select few in the world can offer at the price you can afford. Don’t make the mistake of letting this great price fool you. Behind the Katech 550 Engine is over 30+ years of master engine building, designing, development and testing experience.


Power and durability is the heart and soul for the Katech 550 Engine Package and the Katech Engineering and Motorsports Team wanted to give it the spirit of affordability. Using every bit of our knowledge, we rigorously tested the Katech 550 Engine Package to make sure it would meet Katech’s relentless demands by passing through our multiple engine dyno cells and durability programs which are second to none worldwide. You may ask, “What are these durability programs Katech uses or why are they significant?” Well for starters, the 550 utilizes Katech CNC-ported cylinder heads with a matching valve train and was tested in the Katech Motoring Cell #1. Katech knows valve train is a critical system in any performance engine which is why Katech used every bit of the 7500+ RPM Cell #1 to make sure the 550’s valve train would prove stable and reliable. No corners were cut when the 550 faced Katech’s validation test. Twelve drums of fuel and 20 hours later, the 550 had passed validation on the Katech dyno while running the simulation of the 24 Hours of Daytona. Why Daytona? The track has great advantages for validation testing with its extended power pulls between the bus stop chicane thru the NASCAR turns three and four back to turn one and then blasting at wide open throttle.


To meet the Katech standard, an engine package must not just survive the demanding validation testing, it also must survive inspection. After tear down and all components passing inspection (Katech even considered reassembling the engine to run additional hours), not only did this package meet the Katech standard, it exceeded them and is why it has been named “The Katech 550 Engine Package.” By now you must be asking, “What is the price of the 550?” Well, Katech is over-joyed to announce the price of the fully validated, dry sump 550 Engine Package at $17,999! Power and reliability all offered with affordability and no sacrifices. Inquire today so you can be racing tomorrow with the 550 as your driving force and remember, the Katech Engineering Department will bring you the data and design you desire while the Katech Motorsports Department delivers you the support all the way to the finish line!

Katech now manufactures remote clutch bleeder kits for the C5 Corvette.  Our C6 bleeder has been very popular and customers have commented on the quality over other units so we decided to make one for the C5 Corvette also.  The kit fits 1997-2004 Corvettes and allows you to bleed the clutch from under the hood, rather than the very difficult position of under the car.  It also makes for a great way of flushing out your clutch hydraulic system and completely exchanging the fluid, prolonging clutch hydraulic system life.  The bleeder is a great addition to our LS9X and LS9R clutch kits now available for C5.

Katech Value 427 LS3 Update – 605HP/575FT-LBS!

We have wrapped up durability testing of the new Value 427 LS3 engine that will replace the old Value 427 LS2, Value 402, and Value 416.  We learned some surprising things during the durability test that we will be sharing in the future, a result of which has brought a more durable package to the table that is offered nowhere else.
































The first few engines are being assembled now and we are taking orders.  The engine will be sold in a short block form, or if you want us to take the build further we can build a long block or complete engine.  We have developed a camshaft that has met the power goal of 600hp and will be the standard for Value 427 long block and complete engine packages.  Above you can see the dyno graph from our testing.  These figures were reached with the production intake manifold, so gains could be greater with a FAST manifold.


For more information or if you would like to place an order, please email us.  Stay tuned for more detailed information on exact pricing.

NEW Katech Performance Logo T-Shirts only $8*!

We now have the new Katech Performance logo t-shirts available in white and black.  Sizes from S-3XL.  Even though cotton prices have doubled since the last time we ordered t-shirts, we were able to make this great deal and keep the price the same as before.  S-XL are $8 and *2XL/3XL $10.  These are not cheap shirts either.  These are Gildan 5.3oz heavy cotton.  Even though I wear these shirts every day to work and have washed them many times, they still hold up well.  That is why when I reordered the shirts I made sure to order the same Gildan 5.3oz as before.  At $8 a piece they are a great shirt at a great price.  You can buy a couple and not break the bank.  Buy for a friend.  Or it makes a great inexpensive stocking stuffer for a family member.
