The Corish Brothers' Australian-built, LS-based V12 engine is set to debut publically at the Specialty Equipment Manufacturers Association show in Las Vegas on November 1. The V12 LS engine will be mounted in a chopped and lowered 1967 Chevy Camaro built by Quality Custom Rides. QCR's founder Mike Heim actually bought the Camaro as his first car in 1981 at 18 years old and he's had plans to chop it for a couple decades.

Numerous teasers have shown both the car and the engine, which measures 519 cubic inches or 8.55 liters, and builder Shane Corish told Street Machine TV in June that the engine is basically two aluminum LS1 blocks with one-half cylinder cut off one and one-and-a-half cylinders cut off a second. Shane then mated the two blocks in the center of the half-cylinders before re-sleeving all 12 bores. The crankshaft was custom-designed by Matt and made from billet by Clive Cams in Victoria, Australia.

The prototype engine was then shipped to the United States, where V12 LS co-founder Matt Corish has undertaken installation on the QCR '67 Camaro. Here is Matt talking briefly about the engine and the car in the Quality Custom Rides shop.

That installation has included a dozen individual throttle bodies and some wild-looking six-to-one headers.

So what's it sound like? The V12 LS Youtube Channel uploaded a short teaser clip of it firing up in June before it was shipped stateside and given the custom headers.
