Also discontinued is the replacement LS427/570.
The LS7 debuted in the magnificent C6 Z06.
The American automakers have all had their share of exceptional V8 engines. The last 20 years have been good, really good in fact. One of our favorites, hell we love them all, is GM’s gargantuan LS7 V8 which started out in the C6 Chevrolet Corvette Z06.
The big naturally-aspirated 7.0-litre V8 produced 505 horsepower at 6,100 rpm and 481 lb.-ft. of torque at 4,800 rpm in the 5th generation Camaro Z/28. The V8 was happiest above 4,500 rpm where it not only all of its power but created a sound that made our arm- and neck hairs stand at attention. The roar bellowed all the way to the red line, and it would happen all over again after an upshift.
It, and its replacement, the 570-horsepower LS427/570, will no longer be made available from Chevrolet. According to Road & Track, GM has no plans to substitute it with another engine of the type. Although GM does have plenty of other crate engines on offer, the LS7 was a rare all-motor high-revving V8 that even a boosted engine like the LT4 (supercharged 6.2-litre V8) can’t quite replace.
Chevrolet will fulfill the final current orders and after that, it’s curtains for the LS7
