Now available, a set of eight X2 valves can be yours at the extraordinary value of $250 for a Small Block Chevy and you can take advantage of some professional valvetrain tutelage in the form of on-the-phone support from Marty Zimmerman.

Zimmerman is our X2 product manager and this valvetrain veteran has more than a quarter of a century of experience in the racing industry. In fact, his race resume includes work with a variety of engine and race teams, not the least of which is Evernham Motorsports at the NASCAR Sprint Cup level as a cylinder head professional.

X2 valves were born from Xceldyne, the leader in world-class racing Continue reading

Used to be a time when, if you wanted to fiddle with the pushrods on your racecar engine or conduct a valvetrain test, it was pretty much an exercise in trial and error. And because you can’t visually inspect the inside of your engine without X-ray vision, these tests ended up being more error than trial.

But with the advent of the SpinTron valvetrain testing machine — along with the accompanying technical support to operate and interpret data — CV Products’ racing parts warehouse offers customers the ability to “see” inside your engine while it’s running at a full range of rpm values.

That’s something you won’t get from other providers of high-performance racing parts and accessories. To be able to identify, document and record vital characteristics of your valvetrain — and do so precisely — offers you the opportunity to correct valvetrain incidents, which of course leads to better performance and longer engine life.

There are only about 100 SpinTron machines in operation in race shops throughout the United States today, and CV Products is proud to announce that we own one of these wonders. And now we’re renting it out to you — our customers.

The SpinTron, which first emerged just two decades ago, uses a powerful AC electric motor to spin the crankshaft and valvetrain of a racecar engine. A laser camera is employed to track the Continue reading

Our Xceldyne Valvetrain System features 8° titanium valve locks and titanium spring retainers in order for both to be properly seated to the valve stem and not rotate freely when pulled together. A proper fit for these three components ensures the strength and durability of your valvetrain. As a result, the Xceldyne 8° configuration is quickly becoming the top choice of engine builders.

Xceldyne valvetrain components feature manufactured locks and retainers that are designed to fit like a glove with our titanium valves, providing a match that we readily stake our reputation on as being the strongest, most reliable valvetrain system for any race application you might have in mind.

Our titanium retainers are CNC-machined to provide among the highest Continue reading
