Both Hennessey Performance and the Ford GT need no introduction. The former is already famous for uprating almost anything Cadillac and Chevrolet have to offer, among various vehicles from other brands, while the latter is the last supercar to come out of Dearborn. So is there anything Hennessey and the Ford GT have in common? Actually, yes! The Texas-based shop is now offering a mind-boggling engine upgrade that turns the GT into a 1,000-horsepower beast.
