GM’s LS engine is a gem. Wether it’s factory-fitted to your production car, dropped in as a crate engine, or swapped from a junkyard wreck, the General’s small-block V8 is nearly limitless.
But what if you want something more? Well, Australia has you covered.
Yes, Down Under is the home of V12LS, a company building, well, a V12 engine made from smashing two LS1s together. The resulting 9.5-liter engine debuted at the 2016 SEMA show, where the first prototype engine made 641 wheel horsepower in a heavily-modified ’67 Camaro.
Now, the company is working to build a one-piece block, available in either cast iron or lightweight aluminum. The goal? To make 1000 naturally-aspirated horsepower from a V12 with the same bore and stroke as a factory LS1.
V12LS plans to offer engine builder packages starting at $21,300 delivered, including the block, heads, crank and cam. More complete options are also available, going all the way up to a $46,200 turnkey package with fuel, spark and lubrication system and a standalone ECU. All you’ll need is headers, the water pump and front-end accessory drives. The V12 even uses the same engine mounts as a factory LS1, located the same distance from the rear of the engine as a factory mill. You’ll just have to figure out how to fit the front of the engine in your application—the V12 LS is roughly 8.8 inches longer than a stocker, all added to the nose of the motor.
Here’s how V12LS makes its custom engine block using stock GM dimensions. And hey, if 12 cylinders isn’t enough for you, we know where you can get a GM-inspired quad-turbo V16…
