Tom Nelson on Instagram: "Our 632 Hot Rod Series will surprise you with how lightning-fast it revs. This is a hydraulic roller, pump-gas engine you can drive anywhere—even with the A/C blowing in traffic—and it has a torque curve that’s almost as flat as a ruler. This engine never produces less than 700 ft-lbs of torque from 3,500 to 6,300 RPM, with a peak of 804 ft-lbs."
