2 Performance Products OUR 40 YEARS OF RACING HERITAGE! Back in the late 60s the Cloyes engineering team, headed by Mr. Bob Bub, saw the surging popularity of the weekend racer and set out to develop products to service the race crowd. In 1970, Mr. Bub and his team developed and marketed the very fi rst True Roller Speed set. With its balanced and multi-keyway sprockets, hand-matched with a new chain featuring solid bushing type rollers, the True Roller set was designed for racing and changed the timing game forever. In this 1972 letter, Junior Johnson attributes the new Cloyes True Roller set to aiding in their win at Atlanta (with Bobby Allison driving). They won 10 races that year. The Cloyes name soon became known for the best racing timing set in the U.S. As racing grew both professionally and at the enthusiast level, the Cloyes line of High Performance cam drives grew with it. Over the years, Cloyes engineers have collaborated on projects with some of the legendary names in racing names like Hendrick, Roush, Yates, Dorton, Mondello, as well as the major racing programs at GM, Ford, Mopar, and Mercury Marine. As competitors came into the market with copy-cat speed sets, we needed to take it up a notch. In 1992, Cloyes developed and patented the Hex-A-Just True Roller. Hex-A-Just was an industry fi rst, allowing an engine builder to easily adjust valve timing with the turn of an allen wrench, saving hours on the dyno or at the track. We soon added our Quick Button 2 pc Timing Cover allowing easy access to the timing adjustment. We now have over fi ve patents that compliment our Hex-A-Just system, which remains the premier adjustable timing set on the market. Cloyes Wins Indy!! Cloyes helped power Arie Luyendyk s winning car at the 1997 Indianapolis 500. This was the fi rst race featuring the Olds Aurora racing engine. Because of our close ties to GM, we were asked to make the timing set for their entries in the new Indy Racing League. Until its demise in 2006, all the Pontiac Firebirds running in the IROC Series (International Race of Champions) were equipped with a Cloyes True Roller set. More recently, we ve made special timing sets for the prototype engines you see running the 24 Hour races at Lemans, Sebring and Daytona. Over the past 40 years, it has been our innovation and attention to detail that has set us apart from the rest. Today, Cloyes custom race products are in winning engines at all racing levels across the country and around the world. We continue to work for you, the professional racer. We know what s on the line when you head to the track. We are committed to continue providing the unmatched quality and performance you expect to keep you ahead of the competition! We thank you for your continuing support...40 years and counting!

Our monster trucks put these components to the test as we run high temperatures in our motors during the 90 second to 3 minute freestyle competitions and during racing. In the 27 years we have been racing monster trucks we haven t come across a roller chain set that lasts as long with little stretch as Cloyes. We also like the adjustability of the cam sprocket which enables us to dial our cam degree in easier than other brands. Based on our experience and compared to other products Cloyes is your best bet for any application be it performance or street vehicles. Michael Vaters Black Stallion Monster Truck Racing Producing over 1500 reliable HP with a traditional Pontiac engine is a challenge. I have been utilizing the Cloyes True Roller Timing sets on these engines for 12 years without a single timing system failure. This is with open valve spring pressures in excess of 1000 PSI and engine speeds in excess of 8000 RPM. In a match race environment, consistent performance and reliability are paramount. We have never had a cam timing related issue with the Cloyes chain drive. Michael Garblik Grocery Getter 1963 Pontiac Tempest Drag Car 1

4 FEATURED PRODUCT GM s LS Engines TRUE ROLLER SETS FOR ALL YOUR LS NEEDS! We start with sprockets machined from premium billet steel on state-of-the-art CNC equipment. Both sprockets are then induction hardened and oil-quenched using our in-house multi-stage heat treat process. Our sprockets are made oversized to eliminate the chain slack found in the OE and other aftermarket sets. The cam sprocket is machined for and includes a captured thrust bearing to reduce friction. Our Premium True Roller chains feature superior strength with full roller action. Side plates are cut and shaved from high strength steel and heat-treated for maximum fatigue resistance. The.250 rollers are cold rolled and hardened to exacting standards increasing load and RPM capabilities. All our LS sets are hand-matched at our manufacturing facility to qualify center distance and run out. This is a Cloyes Exclusive - no one else in the industry takes the time and attention to detail to ensure you get the very best custom set in each and every box. We offer LS sets in our patented Hex-A-Just series allowing easy timing adjustment of +/- 6º, as well as in our Race Billet series which are available with three or nine keyways. New Coverage for Raised Blocks and also an EXTREME DUTY Race Chain! LS sets now available with increased center distance for the RHS and other.390 raised blocks. Also new this year, all our LS sets are available with the well-known racing chain currently being used by the leading 24 hour endurance teams...

6 FEATURED PRODUCT Hex-A-Just 4.6L 2V Increase both torque and horsepower with improved cam timing balance. This engine is unique in that the individual bank valve trains are controlled by two separate chains and cam sprockets. The patented Cloyes Hex-A-Just system allows you to quickly make adjustments to balance the right and left banks and meet any custom cam specifi cations required to maximize your engines output. This is not a two-piece sprocket design. This exclusive Hex-A-Just product is a one-piece sprocket design that functions in the same way as the OE confi guration. It utilizes a stainless steel adjuster plate of specifi ed hardness and thickness that replaces the OE cam sprocket washer. Wide tolerances are an inherent flaw with any mass produced OE part. This is corrected by the fact that our sprockets are precision machined from premium billet steel on our state-of-the-art CNC equipment. Special care is taken to tolerance critical features (bore fitment, keyway fitment, timing angle, etc.) for each high performance sprocket manufactured. All sprockets are then induction hardened and oil-quenched using our in-house multi-stage heat treat process. The dynamometer graph shows noticeable torque and horsepower gains as a result of corrected camshaft positions from a simple bolt-on. Your additional fi ne tuning results in maximum gains. Patented Hex-A-Just allows +/- 4 Induction Heat Treated, Billet Steel Sprockets Precision tooth profile for ideal chain mesh Precision machined keyway and bore fitment Exclusive light, fine finished performance chains 2V - Full Kit - Includes ALL the timing components; two Hex-A-Just adjustable billet steel cam sprockets, billet steel crank sprocket, two fi ne fi nish chains, all guides and tensioners. 2V - Upgrade Kit - Everything in this kit is an upgrade from OE; two Hex-A-Just adjustable billet steel cam sprockets, billet steel crank sprocket, two fi ne fi nish chains. 2V - Sprocket Kit - Includes the two Hex-A-Just adjustable billet steel cam sprockets.

7 FORD 4.6L MODULAR ENGINES Hex-A-Just 4.6L 4V As with the 2V, the 4V has the same potential to increase both torque and horsepower with improved cam timing balance. This engine is like the 2V in that the individual bank valve trains are controlled by two separate primary drives, but in addition the 4V utilizes secondary drives to control the intake cams. The patented Cloyes Hex-A-Just system allows you to make the needed adjustments to customize your valve train settings. Our primary cam sprockets allow you to balance the banks, while the 9-keyway secondary cam sprockets give you the tools required to adjust exhaust cam to intake cam overlap. This is not a two-piece sprocket design. This exclusive Hex-A-Just is a one-piece primary sprocket design that functions in the same way as the OE confi guration. It utilizes a stainless steel adjuster plate of specifi ed hardness and thickness that replaces the OE cam sprocket washer. All of our sprockets are machined from premium billet steel on our state-of-theart CNC equipment. Special care is taken to tolerance critical features (bore fitment, keyway fitment, timing angle, etc.) for each high performance sprocket manufactured. All sprockets are then induction hardened and oil-quenched using our in-house multistage heat treat process. Patented Hex-A-Just allows +/- 4 Induction Heat Treated, Billet Steel Sprockets 9-keyway secondary cam sprockets allow +/- 4 Secondary sprockets adjustable in 1 increments Precision tooth profile for ideal chain mesh Precision machined keyway and bore fitment Exclusive light, fine finished performance chains Upgraded secondary racing roller chains Our one-piece billet steel cam sprocket design, used on both 2V and 4V applications, works identical to the OE confi guration by using our custom adjustable washer. 4V Upgrade Kit Everything in this kit is an upgrade from OE; two Hex-A-Just adjustable billet steel primary cam sprockets, two 9-keyway billet steel secondary cam sprockets, two 1-keyway billet steel secondary cam sprockets, billet steel crank sprocket, two fi ne fi nish primary chains, two upgraded secondary roller chains.

30 CENTER DISTANCE & HAND MATCHING What is Center Distance? Center Distance (or CD) is the measurement from the center of the camshaft to the center of the crankshaft. Accurately matching your timing set to the center distance of your engine will determine the performance and longevity of your timing set. CD = MOS - (CRANK DIA./2 + CAM DIA./2) Hand Matching... A Cloyes Exclusive! All of our premium Race sets (Hex-A-Just, Quick Adjust, Race Billet, and Original True ) are hand-matched at the Cloyes manufacturing facility by trained personnel to qualify center distance and runout. Each and every set is measured, by hand, under a predetermined load to determine the exact center distance of each set. It is this attention to detail that sets Cloyes apart from the rest of the pack. If you are ordering an undersize set, put your confi dence in the fact that these sets are also hand matched to make sure you are getting the precise center distance that your align honed engine needs. Reduced Center Distance Sets! Look for the in the application listings on pages 6 through 17. Many of our premium Race sets (Hex-A-Just, Quick Adjust, Race Billet, Original True ) are available in reduced center distance of and This is noted in the application listings by the symbol next to the part number. To order a reduced center distance set: Simply add -5 or -10 to the part number. For example, A-5 or A Under? We sometimes have limited supply of.015 reduced center distance sets for SB Chevy, SB Ford, and SB Chevy Rocket. Contact tech for details. Aluminum Block? Given the unique circumstances of certain aftermarket aluminum blocks, Cloyes can custom match your timing set oversized to accommodate material expansion. 28 CALL OUR TECH LINE AT (479) ext 228 or VISIT

31 TECH INFO - TIMING CHAINS The racing world has different levels of performance and the same is true of the performance parts world. There are different levels of speed sets also, and it is important to match the set to your needs. As a general rule, you want to upgrade your timing set as you upgrade the rest of your valve train components. Within our own product line, we offer two different levels of speed sets - STREET and RACE. The factors that separate them are sprocket material, heat treatment, chain type and level, matching, and adjustability. See page 32 for a quick reference feature comparison. all ChaINs are NOT CREaTED EQUal Probably the most critical part of your timing set is the Timing Chain. Key requirements to a quality chain are the component materials and the manufacturing processes. Each chain component: pin, bushing, roller, and link perform a specifi c function and therefore require a particular material and heat treatment for each of their individual needs. Each component is designed to provide excellent wear properties as well as ductility to endure shock loads. This balancing of both hardness and ductility can only be accomplished by controlled manufacturing processes. SEAMED vs. SEAMLESS ROLLERS This seemingly endless and age-old debate really has no merit. The fact is, it doesn t matter if a roller is seamed or seamless as long as the proper material, heat treatment, and manufacturing processes are implemented. Our standard Street True Roller chain, which we manufacture with seamless rollers, has proven to be an excellent entry level performer. The Cloyes Premium True Roller chain, which has seamed rollers and is used on all our premium race sets, is racing and winning at tracks across the country and around the world. The extremely high-end Cloyes Z chain, a new option on our LS applications, also has seamed rollers and is being used by many of the leading 24 hour endurance teams. So in conclusion, it s less about the seamed or seamless roller, but more about the material used, the manufacturing processes, and a commitment to quality. MATCHED vs. UNMATCHED - WHICH DO YOU PREFER? Another often asked question is about chain defl ection. The illustrations below display typical chain defl ection (in inches) on a mass-produced OE design vs. the chain defl ection on a hand-matched Cloyes True Roller set Defl ection ⅜ Defl ection 0 Mass Produced Cloyes True Roller Set 29

32 ADJUSTING YOUR VALVE TIMING Why Advance or Retard Valve Timing? Adjusting your valve timing gives you the ability to customize your torque and power curves to optimize your desired engine output for your specific application needs. ADVANCED TIMING = MAXIMUM TORQUE AT LOW RPM Recommended for towing, performance street driving, and drag racing with automatic transmissions. RETARDED TIMING = MAXIMUM TORQUE AT HIGH RPM Recommended for circle track, drag racing with manual transmissions and other all-out racing applications. How to Advance or Retard Valve Timing Cloyes offers several different options to adjust your valve timing: HEX-A-JUST With the simple turn of an allen wrench or fuel pump eccentric, our patented Hex-A-Just systems allow you to infinitely adjust valve timing within a window of + / - 6 degrees. QUICK ADJUST Another Cloyes patented and innovative way to adjust your valve timing. By simply loosening the six fasteners and using the supplied tool you can infinitely adjust valve timing within a window of + / - 6 degrees. MULTIPLE KEYWAYS Use our three or nine keyway crank sprockets for incremental adjustments 30

33 TECH INFO - KEY TERMS Key Terms center distance - The calculated distance between the center of the crankshaft and the center of the camshaft when installed on the engine block. See page 28 for more info. timing set center distance - The calculated distance between the center of the crank sprocket and the center of the cam sprocket with regard to chain pitch and tooth count. runout - The amount of linear variation as a timing set rotates. Excessive runout will negatively impact performance. Cloyes exclusive hand matching - Cloyes process that qualifies our premium race sets with respect to center distance and runout. The center distance is matched to your specific application and runout is minimized by tedious quality standards. See page 28 for more info. custom center distance set This can be an undersized set for align honed blocks or any custom size to match a customer s block measurement. See page 28 for more info. oversized sprockets - Unique Cloyes manufactured process that allows Cloyes to achieve correct center distance on particular sets or applications. This is especially important for achieving proper fitment for optimum performance. cheater tooth profile - US Patented tooth profile by Cloyes under Patent # 5,848,948 which provides improved chain wrap, complete distribution of torque loads, and accommodates the components as the system wears with use. matched gear set - Cloyes process that qualifies a gear set with respect to center distance, correct backlash, and runout. induction hardened - Cloyes process that heat treats the teeth of a sprocket without affecting the hub/web portion of the part. The advantage is a hardened wear surface where the chain makes contact, yet a ductile hub/web that can withstand shock loads. captured needle thrust bearing - Enclosed bearing that is accommodated by specific sprockets for the purpose of enduring thrust loads from the valve train. This type of bearing minimizes frictional losses between the cam sprocket thrust surface and the front of the block, and also alleviates wear issues. thrust washer Frictional surface part that functions as a wear resistance between the cam sprocket thrust surface and the front of the block. Our washers are available in hardened spring steel and bronze for specific purposes. rollerized cam button An assembled part that contains a thrust bearing for the purpose of setting cam endplay. This part is constructed using heat treated billet and a premium thrust bearing. 31
