Piston rod question

Post by 1969zeitler »

Any difference between the 411 and 411A rods? (besides the A of course).

The main difference is the offset in the pin boss. The later models, "A" have a boss on the connecting rod shank to indicate the up position to orientate the pin offset. The pin offset is designed to reduce low speed piston slap. Either rod needs to be installed with the bearing tangs on the bottom of the crank.
