If you are thinking you’d like something a little different besides a Chevy small block in your next street rod or classic car build, Corky Coker may have just the answer you are looking for.

Coker tires has been supporting hot rodders and classic car builders for years with speciality tires that are true to history, and he’s also a real car buff. Now, Coker has taken it a step further by revealing the Lencki Six Mark II at SEMA. And boy, is it something.

The original Lencki Six was an engine comissioned by racer Joe Lencki for Indy Car racing. The mill was designed by Leo Goosen and assembled at the Offenhauser shop in California. It first competed in the Indianapolis 500 in 1939, finishing 14th, and versions of the engine continued to compete in America’s most famous race until 1963.

The double overhead cam straight six engine was quite advanced for its time, and the proof comes from how long it remained competitive in Indy Car racing. Even after it was “retired” from the field of competition Lencki kept the patterns and all rights to the design he comissioned.

And now, based on those patterns, Corker and Mike Cunningham have teamed up to create a new Lencki Six with a few modern touches that they are calling the “Mark II.”

Almost all of the flavor of the original engine remains, but with touches to add power and reliability. For example, the Mark II still retains the original Weber intake casting, but the carburetors have been cleverly swapped out for a FAST EFI system. And at first glance it may look like an old-school magneto is still delivering spark to the hemispherical combustion chambers, but that’s really a well-disguised distributor. The original Lencki Six produced a very healthy 416 horsepower back in 1955–which is why Coker fondly calls it an “Offenhauser on steroids”–but the Mark II improves upon that by pumping out over 500 with a pump-gas friendly 10.5:1 compression ratio.

Coker says that while this engine is obviously perfect for Indy Car restoration projects, it will also be great for high end hot rods and even the occasional classic boat. We’re hearing that they are taking orders now, but if you want one you are going to have to scrape up around a hundred grand. There’s more information in the video below.
