Here is some serious horsepower. A Chevrolet big block with twin turbos, loosely modeled after the Nelson Racing Engines piece. 572 cubic inch, 1300 HP on pump gas, 2000 HP on race fuel, and can be used as your daily driver. Lots of detail, 95+ objects, including fuel injectors, throttle-body parts and detailed symmetric turbo pieces, most fastener heads, but no internal engine parts. Includes air-box / intercooler stuff, though depending on application, revision may be needed. Dimensionally correct within reason, but not an exact reproduction.
