New sprint car crate engine program using factory-sealed Chevrolet 602 and 604

By Bertie Scott Brown –  Boardman, Ohio: When Pace Performance discovered sprint cars in the northeast spent more time languishing in garages because owners couldn’t afford to race them, they decided to try a different approach. Last year, 2014, they prepared a Chevrolet Performance factory-sealed 602 and tested it over a full season of racing against traditional 305-powered machines. It proved competitive, finishing regularly in the top five, durable, and overcame the cost obstacles. This year they are launching their new crate engine program offering the 602 and 604. The 602 generates 400hp @ 5,600rpm and 440lbs ft of torque @ 3,800rpm and costs $3,975. The 604, on the other hand, is equipped with fast-burn aluminum cylinder heads and a more aggressive camshaft. Both engines are provided with a Crate Innovations crank balance hub and slip yoke assembly.       The process GM delivers the crate engines to Pace Performance with factory-sealed fasteners. Pace adds a cam spud to the rear of the camshaft which drives the fuel pump and power steering pump if required. Then their partner Race1, headed by Brad Hibbard, installs secondary cable seals on the existing engine fasteners and applies tamper-proof tape over the seals with a QR code. Should a tech inspector wish to scan it with a Smart phone, a page will appear that identifies every seal and its location as well as every serial number. Like to see a 602 sprint car in action?

New 454cu in engine block: World Products launches formidable Windsor-style competitor

New 454cu in engine block: World Products launches formidable Windsor-style competitor

By Alfie Bilk:  Introducing a new engine block with big power potential, understandably, gives rise to a sense of occasion. First, consider the time and treasure invested in its creation. Also, consider the enormity of the engineering details and the designer who tirelessly examined hundreds of complex regions of the new casting. It’s an endeavor not for the faint of heart. But its culmination is exactly what we observed at the end of 2014 when, during the PRI exhibition in Indianapolis, World Products unveiled two innovative Ford-based blocks. Both defined as small-blocks they are distinguished mainly by their deck heights: one measures 8.2in., the other 9.5in. The 9.5 version displayed in finished form sported a displacement of 454cu in (7.4L), exhibited a host of advantages, and echoed the biggest engine news of the show. It is called Man O’ War. The Man O’ War block had existed previously, but when World Products was sold in late 2012 the new owners decided to entirely revise it. Now graced by new architecture and the brainchild of World’s Engineering Director, Dick Boyer, it accommodates the original 10-bolt cylinder heads as well as the latest aftermarket high-performance 18-bolt counterparts. Introducing six head bolts per cylinder combined with extra thick decks greatly reinforces gasket clamping. But its sporting credentials didn’t end there. Devoted to the idea that the new engine should be the strongest and most rugged, Boyer, an accomplished race engine builder and tuner, cast the new power unit in a 40,000psi iron alloy. He also increased the thickness of the main bearing webs, upgrading the front one by adding 0.080in and the...
Dramatic first ChumpCar endurance event of 2015

Dramatic first ChumpCar endurance event of 2015

By Freddie Heaney – Road Atlanta, GA: ChumpCar staged its first nationwide event of the 2015 race season with a well-supported 14-hour endurance race. “Life has an expiry date,” as they say, “let’s do something!” Of the ninety-two entrants, some originating from as far away as Canada, the ChumpCar opener was won by a 1999 Saab driven by an upstate New York-based team called Tired Iron from Sauquoit. In fact, this same car triumphed at the 2014 ChumpCar Daytona event and yet another of their Saabs finished fourth at Road Atlanta. What’s their special quality you might ask? A reputation for building fast reliable Saabs and selecting fast evenly matched drivers—usually four. The trouble with flags Saturday, February 7, turned out to be a warm mid-winter day with blue skies, grateful enthusiasts escaping their snowy thermal prisons in the north and the promise of close, enjoyable racing. In fact, sometimes too close which precipitated a couple red-flag periods. The red flag carries a symbol of urgency, signifying all racers must come to an easy stop, pulling over to track edge and out of the way. But endurance racing, where hundreds of drivers participate, has by nature a potential for error: some proceed to stop as fast as possible with dramatic clouds of tire smoke, while others fail to pull over, blocking the track for those cars racing up behind. Even more sinister, perhaps, was the sight of the black flag, brandished around 5:45 just before nightfall. This compelled all racers to return to the paddock for a “Call-to-Jesus meeting.” With racecars parked in two neat, long lines along the...

Dazzling art of heel-and-toe

On modern racing cars, throttle blipping on down-shifts is activated by the paddle-shifting mechanism on the steering wheel. But during the last century it was the work of the driver’s right foot…

Why people struggle with serpentine pulley systems

Why people struggle with serpentine pulley systems

By Archie Bosman: When you decide to invest in a serpentine pulley system, many of which cost around $2,000 and beyond, naturally, you want your endeavor to be a potential award-winner. But the new system should not only look good but also fit well.  It is also crucial that the kit includes all the brackets, pulleys, accessories, belt, as well as power steering and air conditioning provisions. And if the manufacturer takes pride in their work you’ll find all the fasteners, spacers, and gaskets, individually identified. Joe Rode of Eddie Motorsports explains the basics and offers advice on how to select a competent serpentine belt system.
