To consolidate the facts, @Gene, Long rods mean more torque. Long stroke and long rods equals lots of torque. Tractors have crank off center to bore and long rods and long stroke Huge torque low rpm's! 302 Chevy short rods short stroke low torque HIGH rpm's. 10,500 rpm's not unheard of but 6,500 -7,000 to get it off the line is also not unheard of. Norton's long rods and off center to bore equals a high torque and a engine that doesn't like high rpm's.
302 Chevy has a 5.7" rod 5.7/3 = 1.9:1 rod ratio. That's a fairly large rod ratio.

400 Chevy SB has a 5.565" rod 3.75" stroke. That's a 1.484:1 rod ratio, much smaller rod ratio.
