Instead of 1,000 ponies under the hood as in last year’s model, the company has cranked up output to an even more Texas-sized 1,200 hp. How was this done? Starting off with a stock 2013 Ford Shelby GT500, the 5.8-liter V8 was stripped down to the block and given an array of upgrades via improved engine internals and forced induction as well as a cooling package. An adjustable suspension and larger brakes were added in order to handle that extra 200 hp. Sound good? We thought so, but the price may have you thinking twice: $154,995 will get you just the upgrade kit, plus another $54,650 for the donor GT500 Mustang.
