The turbocharged 454 from Demon Engines produced 776 hp and 732 lb-ft of torque. Torque production exceeded 650 lb-ft from 3,500 rpm to 6,200 rpm. More power was on tap with higher boost levels (beyond 8 psi), but the homemade turbo kit definitely served its purpose. Remember, these power numbers came from a short-block equipped with a cast crank and stock rods.
