Sure, the Chevrolet Camaro Z/28 has been out of production for quite a few years now but it still remains one of the most focused and driver-oriented Camaro models built in recent decades. For owners looking for a little extra performance, Lingenfelter has come to the party.
The crown jewel of the fifth-generation Camaro Z/28 was always its engine. Whereas most other high-performance Camaros launched since have relied on forced induction to achieve monumental levels of power, the Z/28 has a 7.0-liter naturally-aspirated V8 that was co-developed with Corvette Racing. This was one of the finest engines that GM was producing at the time and delivers 505 hp and 481 lb-ft (652 Nm) of torque.

One could argue that these figures are just about perfect for a street car. However, Lingenfelter’s upgrades push the envelope even further without relying on forced induction. That’s right, the tuner opted to make a host of internal upgrades on the 7.0-liter V8, rather than simply slapping on a supercharger and calling it a day.
Lingenfelter’s upgrades start with the heads being CNC ported and polished while the compression ratio has been changed to 11.5:1. The engine is also rocking new dual valve springs with titanium retainers and valve locks. The tuner has also gone to the trouble of porting and polishing the throttle body and slotted in larger fuel injectors. There are also new head gaskets and bolts, a 160-degree thermostat, and long tube headers from American Racing.
The result is a cool 660 hp. Lingenfelter notes that the alterations mean the car has a more aggressive idle and isn’t as well suited to everyday driving as the standard car. Fortunately, Camaro Z/28 owners who can’t handle the change in driving dynamics are able to opt for a 630 hp package that is easier to use on the street.
