Warren,

-------As you know, Im not a parts numbers guy, but Im relatively sure that a dimple rod is a dimple rod. Red Alerts motor was built by Tonawanda with dimple rods. Those same rods are still in it today. Whenever I freshened the motor I would take in three sets and have my engine-builder choose the best of all of them and he always said that the originals needed nothing. Both HP427s and HP454s used dimple rods. I dont know the beginning and ending dates for their use on the engine assembly-line. Someone else on here more versed in that stuff and the numbers can probably elaborate on what I have said!!!.........Bill S
