2007 CHEVROLET CORVETTE Z06
At the time of its release, the 2007 Z06 was THE fastest and most technologically-advanced Corvette in its entire 54-year history, up to that point. Exterior changes (from the standard Corvette) and aerodynamics were subtle but effective, many inspired by Chevrolet’s Corvette racing program, especially the LeMans-winning C6R Corvette racer.
2007 CHEVROLET CORVETTE Z06 ENGINE
The ‘Bowtie Boys’ built a very special engine for the 2007 Chevrolet Corvette Z06. The LS7 started out life as an LS-series small block, but was stretched to big-block size. At 7.0-liters, or 427 cubic inches, it blew past the previous record-holder for Chevy small block displacement, the 1970s-era 400. This new LS7 is a technological tour-de-force, and a poster child for the expression: “There’s no replacement for displacement”. This monster motor makes 505 horsepower and shoots the 3,100-pound Z06 to 60 in a scant 3.7 seconds, all in first gear! To get so much displacement out of the small block (with the same bore centers at the original 265 V8), thin-wall steel cylinder liners were pressed into the aluminum block to allow a bore of 104.8mm. Then they stroked it a new forged steel crankshaft, supported by forged steel main bearing carps. The connecting rods, pushrods and valve springs are made of lightweight high-strength titanium. The cam had .591″ lift and the heads were CNC-ported. All this supported a 7,000 rpm redline! Imagine spinning an old school 427 big block out to 7,000. And the Z06 will do it every day.
