The cylinders can be honed 0.005 in. oversize. This keeps the walls thick enough to support boost. A 4.000-in. stroke crankshaft will also increase displacement. The chart below lists the specs for a common bore and stroke combination.
“This is awesome,” the younger Torres said, hoisting the trophy. “Me, my brother, my dad, we’re all so competitive. I knew it was going to be tough, and it could have gone either way [in the final], but we’re always on each other’s team. We have a little rivalry, but we always want each other to do good.” Top Dragster #1 qualifier Steve Will had been to the winner’s circle before in support of daughter and Top Fuel driver Hillary Will Hines, but this was dad’s first victory of his own at a national event.
The CP Carrillo-backed Top Alcohol Funny Car pilot left the starting line with a psychic .029-second reaction time and kept right on going for a 5.425, 269.67 win over Swede Ulf Leanders’ 5.508, 268.33. Aggressively testing in Phoenix prior to the Winternationals paid off for Top Alcohol Dragster driver Shawn Cowie, who scored his 11th national event win and second season-opener Wally with a defeat of Garrett Bateman.
I would like to get about 350 hp out of the new engine and run in the 13s. Is this possible with my combination? Your crate 350 should be okay for use with a TPI system. We recommend checking the engine’s camshaft specifications. Most “computer-friendly” cam profiles are no bigger than 214-222 degrees duration at .050 and .450-.460 inches of lift with 112-116 degrees of lobe separation. If the cam in the new 350 is much over these figures, you should consider a different camshaft to ensure compatibility with the IROC’s computer.
