Wow, it wouldn't have been long before the center of that flexplate just let loose of the rest.

Pretty much every passenger/light truck big block I have seen has the Hi-Perf/Pass cast into the block. It doesn't mean it is anything special.

I haven't found an IVR code yet. I did find the IV code which says '66-'68 325 HP 396 with auto trans, just like you said.
