CORE VALUE: LUNATI’S NEW $225 GOLD VALVE SPRING KIT FOR GM LS ENGINES

Written by Moore Good Ink Olive Branch, MS: Times are lean right now, and especially so for hot rodders on a budget. To address this frustrating inconvenience, Lunati bucks the market with a new LS-engine dual valve spring kit (PN 73925K1LUN) for about $50 less than competitors. With a maximum lift capability at 0.660-inch, the Lunati kit serves the majority of popular camshaft applications. The kit is complete with dual valve springs, steel retainers, locks, valve seals and spring locators and represents a drop-in installation for many popular LS applications. OEM LS engines use single-wire valve springs designed around factory camshafts.  Aftermarket camshafts require new valve springs suited for high lift and serious ramp rates. Lunati’s retainers and spring locators are CNC-manufactured from 4140 alloy steel.  The locators pilot onto the valve guides and locate the inner diameter of the inner valve springs, preventing them from abrading the spring pockets in the aluminum heads. In common with all dual-spring retainers, these new Lunati types have a group of steps machined into their underside (which locate the upper registers of the valve springs) and a bore machined to accept the 7-degree valve locks. The locks are equipped with inner bead locks and the 7-degree interference angle between the locks and the retainers is favored by many who believe it causes the locks to clamp the valve stems tighter. Advantages: Through careful CAD and FEA design efforts, Lunati engineers have developed a new valve spring retainer design using wear-favorable alloy steel, yet nearly matching the weight advantage of Titanium.  For street/strip longevity, Lunati’s lightweight alloy steel retainer is unbeatable.  Viton steel-jacketed...

NEW ROUSH YATES BELT-DRIVE TIMING GEAR FOR FORD WINDSOR-BASED ENGINES

Written by Moore Good Ink Mooresville, NC: It’s no secret that most popular pushrod-engine racing technology, regardless of venue, is rightly born of the rigors of NASCAR racing. Timing gear is no exception. In the late eighties, the dry-running, cog-belt-driven system rose from timing chain failures that frequented NASCAR racers during 500-mile contests. Ostensibly developed for the Roush Yates 358 cubic inch (NASCAR, ARCA, Craftsman Truck Series) and 436 cubic inch (WSORR and TORC off-road series) engines, its new cog-belt system is a precise link between camshaft and crankshaft, tough enough to endure 24-hour races such as Daytona and Le Mans or a full-season of circle track competition. Further, the system enhances any engine based on the Ford Windsor cylinder block. Years of service are assured simply by replacing the belt at recommended intervals (before every race, yearly, or as abuse dictates). Besides producing less friction and being more durable than gear- or chain-drives, the Roush Yates system offers race and high-performance street engines a number of advantages: 1. Adds external accessibility and adjustability of the timing gear itself, which can be advanced or retarded (up to 25 degrees overall) during dyno testing and tuning. No need to remove the front cover of the engine or drain the coolant system 2. Eliminates harmful harmonics to guard against valve train instability 3. Provides billet aluminum upper pulley for additional strength and features cogged-tooth configuration 4. Supplies heat-treated steel cogged-tooth crankshaft pulley for strength and reliability 5. Accommodates both dry-sump and wet-sump oiling systems 6. Features upper vent ports for cooler-running belt assembly 7. Furnishes all Grade 8-spec fasteners for strength...
