Australian V12LS Group Converts an LS1 V8 Into a Custom 1000-HP V12 Engine

Turning a small-block into a long-block

Published October 9, 2017

Engine swaps are probably the easiest way of upgrading one car’s performance. But they aren’t the only way. Turning a brand new V8 engine to custom performance group like the V12LS out of Australia, and getting a beefed up V12 engine version in return, is another one. Highly unorthodox but rather efficient way, if I might add.

Incidentally, V12LS group only accepts one of the most popular engines for swapping ever devised. GM LS1 V8 which powers numerous Camaros, Corvettes and God knows what else isn’t only affordable, durable and easy to fit into most engine bays. Apparently, it’s also easy to work with as Aussies managed to convert it into one steady and coherent symphony of power.

Their first engine was created out of two separate LS1 blocks mashed together into a single 519 cubic inch unit. This prototype could have been seen at the 2016 SEMA show. There it rested inside custom built Quality Custom Rides LLC’s 1967 Chevrolet Camaro. This 8.5L V12 delivered north of 700 horsepower and 600 pound-feet of twist.

Now, they’ve decided to raise their craftsmanship game to an entirely new level. Their latest engine is a one-piece block which required a complete ground up design. It can be had either in all-aluminum or cast iron forms, and it displaces 580 cubic inches or 9.5 liters. Two sets of tunes are available right now with third and most powerful one just around the corner. Stage 1 package is squared off at 600 horsepower and 500 lb-ft of torque. Stage 2 delivers 717 hp and 600 lb-ft of torque. Finally, the upcoming Stage 3 tune should be able to lift this custom V12 engine over the 1,000 horsepower mark with the help of LS7 heads. Furthermore, Aussies are also working on a forced induction version of the mill which should be able to generate an even larger output.

All this power comes at a price, though. V12LS will sell you their long-block for no less than $35,000. You can get yourself a perfectly fine brand new V8-powered pony car for that kind of money. And this wild Australian bunch doesn’t think you shouldn’t. As long as you splash another $35,000 on one of their V12s and swap it into your new ride. Their presentation video is just below.

About Nikola Potrebić

Despite driving a piece of junk, Nikola still manages to survive the harrowing experience called "A road trip in a Yugo," day in, day out. On the other hand, precious few things move him as muscle cars do. Especially those from the bygone golden era, which makes him wonder why wasn't he born a few decades earlier? Well, at least he's been given the opportunity to enjoy the likes of the Pontiak Aztek, Chrysler PT Cruiser, Fiat Multipla, and other lovely millennials, right? Come to think of it, I'll stick with my Yugo. Thank you very much.
