Vengeance Racing in Cumming GA is known for turning out some impressive builds.  Here’s another to add to their growing list.  This C5 Z06 underwent quite a few upgrades during its stay with Vengeance.  The Vengeance team had previously installed a A&A Supercharger Kit, along with some other bolt-ons.  The owner quickly became addicted to boost, and wanted more…lots more!


The goal for this build was to make as much HP as possible, while maintaining streetability.  The stock LS6 block was removed and replaced by a freshly built RHS 427 block.  A Vengeance spec blower camshaft, Trickflow 245cc 6 bolt heads, and ARP studs were also added.  The Vortech V3 Si-Trim was swapped out for the V7 YSi, and the factory 6 rib belt drive was upgraded to a A&A 8 rib drive.  The car went on the dyno and spun the rollers with a vengeance!  The final number, 879 RWHP & 749 RWTQ w/15 PSi on 93 octane!!

This one clean Z06!  The rumble from the exhaust at idle, and that sweet Vortech V7 blower whine let unsuspecting car enthusiasts know that this monster is far from stock.
