Recalling a legend.
Today, we say goodbye to the Chevrolet LS7, one of the most powerful V8 engines ever made. This monster V8 was first seen in the Corvette Z06 where it quickly became a fan favourite. The LS7 was also used in the Camaro Z/28, before being made into a crate engine for Chevrolet’s performance parts program. Chevrolet has stopped orders for this legendary crate engine after years of service, leaving us with a 7.0-liter gap in our hearts.
The C6Z06 was the first vehicle to debut the LS7. It caused shockwaves across the automotive industry. The 7.0-liter V8 produced 505 horsepower (376 Kilowatts) at 7,000 rpm. There are many V8s that are more powerful, but the LS7 has more character.
The LS7 has the same displacement and sound as a classic American V8 but it is modern. The LS7 has a forged crankshaft and titanium connecting rods. It also features unique hypereutectic aluminiu pistons. The LS7’s classic 2-valve per cylinder pushrod design is still the best of both old and new. Chevy tested the LS7 reliably at 8,000 rpm, but could not use this redline in production because of limitations due to hydraulic lifters. This rumor is supported by many aftermarket companies that have been able to increase the LS7’s redline reliably.
The LS427/570 was also discontinued by Chevy. This was an upgrade version of the LS7. It used an upgraded camshaft that produced 570 horsepower (425 Kilowatts). To make it easier to swap engines between cars with clearance, the LS427/570 used a wet sump oils system.
Although we will miss the naturally aspirated beauty and power of the LS7 engine, Chevy sold a lot of them so that we can continue to enjoy it for many years. It’s up to you to find one used.
