Default Rotating assembly orientation questions.

Question 1. My pistons are stamped with (L) left, and (R) right, but is that classified as looking at the engine from the driver seat, or the front of the vehicle?

Question 2. My Eagle forged rods are stamped with a casting number on the lower portion of the rod (the larger end). Should the casting numbers be facing the left or right of the motor?

left side is looking at the front of the motor...

if the pistons have dots stamped on the head they ALWAYS go to the front unless otherwise noted.

Left = driver's side, Right = passenger's side.

The rods have a large chamfer on the large end were the rod bearings go , The chamfered side goes to the out side of the crank journal. I don't know what crank your using, but most of the aftermarket cranks has radius on the out side edges of the rod & main journals and the bearing that you order must have the chamfer edge also . If your crank has the chamfered edge and you use a standard bearing with out the chamfer ,when you torque the caps down it will lock the rod or main up the motor will not turn. A stock LS crank does not have that chamfer so you can run a standard bearing but you still haft to turn the rod chamfer to the out side.

These are correct.
