Thanks Verne........ Any idea if this was the same specs used through the late 60s, namely 1969??? I'm willing to bet it was....

Rich,
All my books and references pretty well peter out after '67. sorry. Perhaps someone with later parts books can find out whether the same part number was used through '69.

That is the same Cam they used in the 1969 L-34 396/350 HP,up until the new 402's came out later on,then they switched over to the #4359.
