    If I remember correctly, horsepower should be 235 and torque would be 385 ft lbs. Hope this helps.

    I think the 350 was rated at 210 hp and 300 ft lbs of torque around that time period.

    An old chevy brochure I have from 89 shows the 454 at 230 horse at 3600 rpm and 385 #'s torque at 1600 rpm. The 350 was listed at 210 horse at 4000 rpm and 300 #'s torque at 2800 rpm.
