The upcoming seventh installment of Ken Block's Gymkhana series just may be the best one yet, simply because the video will feature the Hoonicorn -- an all-wheel drive 1965 Ford Mustang packing a Yates 410-cubic inch Ford V8, good for 845 horsepower, and a six-speed manual gearbox. Eye-catching graphics and a set of bronze wheels complete the package. The car was two years in the making, built at ASD Motorsports in Charlotte, North Carolina. It makes its official debut at the SEMA show in Vegas this week. Gymkhana 7 has wrapped, but there's no word yet on a release date.
