Chevy S-10 Pickups Continue To Top Pro Stock Truck Charts; NHRA Exhibition Series Heads To Topeka

Topeka, Kans.; Sept. 25, 1997: The Chevy S-10 Pickups not only continue to top the charts in the National Hot Rod Association's (NHRA) Pro Stock Truck Series, they continue to improve. After five events of this exhibition series for compact pickup trucks, the Chevy S-10 is the fastest and quickest, with John Lingenfelter bettering the S-10's speed and e.t. with every event. Lingenfelter, also the engine builder of the 358 cu.in. Chevy V8 engine equipped in the S-10, set the quickest time of the series so far, at the series' previous event in Reading, Pa. His 7.704-second run in the quarter-mile at Maple Grove Raceway is the best so far, as is his speed of 175.26 mph, also established at Maple Grove. Next on the Pro Stock Truck exhibition schedule is the Sears Craftsman Nationals at Heartland Park Topeka this weekend, where six Pro Stock Trucks from three manufacturers (Chevy, Dodge and Ford) will again face off in head-to-head passes to determine the two quickest trucks for the final elimination.

Jerrry Hass, driver of the second Chevy S-10 and also the chassis builder, holds the second quickest e.t. (7.740) and second fastest speed (174.08). Lingenfelter and the S-10 have won two of the final eliminations so far, Dodge driver Darrell Alderman has won two, and Scott Geoffrion, in a Dodge, has won one. Although the S-10 was quickest and fastest in each final elimination, the Dodge victories were as a result of holeshots (better reaction time). "We test something every run," says Haas. "We've tried different transmission ratios, different clutch combinations, different air pans (for the cowl induction) and different rear tire sixes. We reached our goal at Reading. When we started these exhibition runs we projected that we would run 7.70 and 175 mph. I'd love to put it in the 7.60s. We are absolutely not stopping here. We're a long way from the top of the hill." "There's always more," says Lingenfelter. "We're learning more about what the truck needs each time. Most of our improvements have been in the clutch department. As for the engines, we haven't changed anything in them since we starated. We have been freshening them up, but we actually haven't done any development work."
