RCR builds motors for other teams. To rent an SB-2 engine last year cost $55,000 for one race. Using a real NASCAR motor in a street legal car might be a first. RCR makes a lot of the parts, which is another reason the engines are so expensive and basically not available for public sale. NASCAR's top series has moved to a new engine program (R07), but the Nationwide and Craftsman Truck series both still use the SB-2 configuration.
With each RCR Camaro comes an extra motor, an all-aluminum 427-crate engine and the SB-2 that raced in NASCAR in 2007 and in the Busch series for 2008. In addition to the SB-2 race engine, each RCR Camaro comes with three different engine packages, including a 383 cubic inch crate engine, a fuel injected LS3, and the previously mentioned all-aluminum 427 cubic inch SBC.
Obviously, RCR has gone the extra step to honor Dale Earnhardt. Brooks' first suggestion for a crate motor was the LS3 in the 2008 Corvette. Richard favored an engine a little more period correct V-8 with a carburetor. After months of test marketing, they decided to offer both engines
Brook recalled, "Richard said why don't we put race engines in them. We're switching to a new engine program. We're going to have some of these engines [SB-2] around, and it would be cool to not only offer the fans an opportunity to buy a limited edition vehicle, but to choose a race engine driven by their favorite RCR driver or at their favorite track."
Brook thought the idea was awesome. They both had second thoughts about service. If a race engine needed parts, the owner couldn't go to his local parts store for a fix. After all, the SB-2 is a naturally aspirated, non-roller cam V-8 turning 10,000 rpm and based on a '55 Chevy V-8.
In an e-mail, Brook added, "The perception out there is these engines are boat anchors. I agree that taking an engine that was built to run 600 miles in the harshest conditions and already has 500 plus miles on it is a recipe for disaster. The difference with the Series 3 program is these motors have been rebuilt by the legendary engine shop at RCR (which has now merged with DEI's engine shop to form ECR-Earnhardt Childress Racing. These are fresh SB-2s that have been reconfigured for the street, but still pump out over 600 hp at 7,200 rpm. This is about 70 percent of its capability and obviously leads to a much longer lifespan. In reality, I thought the SB-2 would be more of a trophy and not be the primary engine. That is where the other engines comes into the program, something that we could warranty and repair quickly and easily."
Brook proved the drivability of the first car he built with the SB-2 motor. It works. It is functional. But, he figured most people would rather take the car with the crate engine installed, and put the SB-2 on a motor stand for display in their garage, office or shop as a "cool trophy of the whole package."
