Unhappy 708-cubic-inch, all-aluminum engine for marine use

All-Star 708 cid Big Block based engine?

Were did it go?
The exhaust design and the bellhousing dimensions are the only standards that carry over directly from the original Chevy, which means the Allstar will fit right into standard big block installations. The actual dimensions are about three inches wider, three inches longer and the same height as the standard 502, but the new engine weighs about 150 pounds less.

Those dimensions become even more impressive when you find out that the 708-cubic-inch Allstar puts out almost 900 horsepower and more than 1,000 ft./lbs. of torque at 4,800 rpm. Did I mention that it produces those numbers on pump gas and without a turbocharger? That's right, the Allstar is naturally aspirated.

The last information was that Merc bought the rights! Did they back shelf it with Pressure from GM?

how about Torque eng.

Torque Engineering Corporation designs and manufactures the largest marine gasoline production engine available. This 860 cubic inch/14 liter, aluminum,V-12 powerhouse is designed with an eye toward providing the utmost in high power output, reliable operation and a long life.

Did the company not outlast its engines?

I understand Sterling now owns Torque. Last I heard there were working out a few issues and planned to market the engine. But that was like a year ago.

That is a super cool piece but it sure would throw off your transom hole location from standard Bravo.
