Didn't say you could, wasn't my quote, 473 hp is pretty good, do think you could get the torque numbers up though, 328 lbs-ft is only 1.12 lbs-ft that's pretty low.
Less torque than a stock 340 or 360 magnum. People see that peak number and get all impressed, not realizing that thing would be a turd in a street car with highway gears
