Need a plan - component selection for restoring 68 340 that runs on 91 oct

Starting back with NM comments on the custom pistons. Thank you, I did not realize what went into that choice. I will stick with one of the two flat tops. Actually I am going with the KBs.

Not going to stroke the motor.
So how do the numbers stack up with KB's FTs using either Lunati or the Howards as Wym has suggested as an alternative?

As for AJ's quiz. Never had a 360 and never worked on one. I would recognize my intake manifold in a moment but I don't think that was the test you intended or was it? If not, then I'm really not sure, maybe water pump was different or ah, perhaps the harmonic dampner... is the 360 externally balanced?
