It’s been almost a year since Sixteen Power debuted their custom 14.0 L V16. The engine is basically two 7.0 L LS7 V8 mated together in a single block that accepts aftermarket heads and intakes. The engine with a mild tune with a mild camshaft made 1,103 horsepower and 1,115 lb-ft of torque on the dyno.
