Cowie surged ahead with a victorious 5.333, 277.03 as Bateman smoked the tires at the hit of the throttle. During World War II, long-range fighter and bomber aircraft were equipped with “Belly Tanks” or “Drop Tanks” full of fuel which extended their range for long-distance flights. After the war, the tanks’ streamlined housings became the go-to choice for hotrodders looking for an aerodynamic body for their Salt Flat racers.
Like other LS engines, a cam swap is common. The LSA has a very small camshaft. Upgrading to a LS9 camshaft is worth about 30 hp, however, it won’t make more power until 4,800 rpm. It’s really only worth it if you plan on running at high rpm. Larger, aftermarket cams can add about 50 hp. Going as high as 0.630 in. of valve lift is also common. The table below gives some information on what to expect from different cams. (Note: We are assuming a standard blower, pulleys, and tune on pump gas.)
“It’s always nerve-wracking pulling the cars out after a long off season, but it was a great race with a lot of great competition,” Rizzoli said. “Phoenix was my first race last year, and I won that one—so evidently, watch out for me at the first race of the year.”
Built for performance, LSA engines didn’t use Active Fuel Management (AFM), Variable Valve Timing (VVT), or Flex Fuel (E-85) technology. The blocks were precision-machined using deck plates. They also had piston oil squirters to improve durability.
