The ASA Engine
This was a very special application LS1 built for the 2000 American Speed Association (ASA). In 1998, the ASA decided to introduce electronic engine management to oval track racing. The new LS1 Corvette engine was a natural fit.
ASA called the whole deal Project 2000. These engines developed 430 hp at 6,200 rpm, with torque reaching 430 lb-ft at 4,800 rpm. The redline was at 6,500, which was the same as the fuel shut-off point. When you compare these numbers to the stock LS1 it's a wonder this engine hasn't been more popular. It shouldn't be that hard to create one of these engines using parts from your Chevrolet parts department or from Lingenfelter.
The ASA initially ordered 300 engines for the 2000 season. I haven't been able to confirm that number, but it sounds reasonable. These engines were assembled at the Romulus, Michigan, plant and then shipped to Lingenfelter, where they were modified, dyno tested, and then sealed. ASA kept control of the PCM boxes and passed out sealed boxes before each race. These were special units developed by GM and had different values from the production units.
These engines used a more aggressive camshaft, higher quality valve springs, and a dry-sump oiling system. In 2000, these engines were sold to the ASA teams for $12,000. I ran across one of these engines last year and the owner was asking $11,000. Not bad considering that it had been raced for a decade.
LS by Kimble
Over the years, General Motors has commissioned cutaway artist David Kimble to render several of its engines for various press kits. Here are a few from the LS era.
