LS3 Power for Grassroots Motorsports' Track Day Vette

Grassroots Motorsports Magazine is the go-to book for features and builds of vintage and modern road race, autocross, and track day cars. When GRM's J.G. Pasterjak wanted more muscle for his C5 Corvette Z06, he turned to the experts at Summit Racing.

They recommended a BluePrint Engines Pro Series LS3 to replace the factory LS6. Out of the box, the BluePrint LS3 puts 465 horsepower and 435 lbs.-ft. of torque to the Corvette's rear wheels. That's a lot of scoot--and there are plans to upgrade the engine to make even more power.

Our OnAllCylinders blog recently posted a story outlining GRM's Z06 upgrade program and what it takes to build a track-day C5 of your own (hint: it's not that difficult). We'll keep you posted about update stories on this awesome Vette.
