Wednesday's NHRA test session for Pro categories at The Strip gave drag racing fans a free preview of the Oct. 24-27 NHRA ACDelco Las Vegas Nationals. Five Pro Stock and six Pro Stock Bike teams participated, as well as Duane Shields' Top Alcohol Dragster from Las Vegas. Pro Stock attendees included Las Vegas' George Marnell, V. Gaines, Allen Johnson, Tom Lee and Ben Watson. Bike entries included Matt Hines, Henderson's Jay Matthews and Scott Lewis. Marnell posted a run of 195.36 mph (7.06 sec.) in his Matco Tools Pontiac, but today's passes were not about top speed. "We don't have a race motor in the car," Marnell admitted. "We have a test motor in it. We're looking for track set-up today. We're saving our good stuff for next week. What we're working on today is definitely going to pay off next week. We ran into a little bit of rough times over the past few races. We've been trying different motor and carburetor combinations and it seemed to pay off. We've got a much better handle on it now and we're ready to rock and roll."
