To say former General Motors Performance Division director and engineer John Heinricy knows how to drive is an understatement. Not only did he take care of the performance driving aspect of engineering for GM for years, he’s an SCCA champion and has a sub 8-minute time around the Nurburgring in a 2009 Cadillac CTS-V.
There are few people better suited to testing out a new GM performance product than Heinricy, which may be why Hennssey Performance Engineering called him out to put their HPE600 Camaro Z/28 through its paces at MSR Houston. The HPE600 package for the Z/28 graces its 7.0-liter LS7 engine with an HPE camshaft, ported cylinder heads, upgraded valvetrain components, stainless steel longtube headers and HPE ECU tuning, resulting in 638 horsepower at the flywheel.
The HPE600 package was developed after a customer approached Hennssey saying the LS7 engine in his Z/28 lacked torque on the straights. We’re sure Heinricy appreciated the extra bit of grunt on offer when coming out of the corners thanks to HPE’s work, and we know for a fact he liked the improved soundtrack.
