V12 LS1 engine – Video

 

A few years in the making, this one of a kind V12 LS1 engine has been pieced together by the Corish brothers at V12LS.com. In essence it’s two GM V8 LS1 alloy blocks and cylinder heads shortened and grafted together using a custom billet crank and camshaft. The beauty of the build is that engine still retains many GM parts. This prototype engine will be heading to the US soon for testing. The good new is the guys plan on making these engines available for sale next year.
