Chevrolet | Corvette : May 4, 2019
Michael brought us his pristine LeMans Blue Metallic 2007 Chevrolet Corvette 427 Limited Edition Z06 to address the LS7's infamous valve drop issues, and also add another ~100whp worth of naturally aspirated power in the process! Up first, John installed a set of CNC ported cylinder heads from Lingenfelter Performance Engineering, custom billet-core camshaft from Cam Motion, push rods from COMP Cams, fasteners from ARP, all new OEM GM gasket, seals, fluids, and timing components (along with a C5R timing chain), with a set of long-tube headers from Stainless Works to top it all off.
After the mechanical work wrapped in the shop, Matt strapped her down to the rollers for Vlad to bring it all together with a custom calibration via HP Tuners. The result is exactly what we were after, coming in at 545.06whp & 512.92lbft! Up next, a ported MSD Atomic intake manifold, Nick Williams 102mm throttle body, and a VaraRam intake to let this LS7 breathe a bit easier. Keep an eye out for more to come from this C6Z in the future!
