Are the 216 rods and 235 rods different length? And if so, by how much?
Rods are the same length. Gleaned from the appropriate Vehicle Info Kits: Rod length 235 6.81 inches vs. 216 6.8125 inches. Essentially the same. Per Jerry and my rough measurements, the crank to deck height is about 1/8 inch more on the 235 to account for the increased stroke.
