77- 225 short block back from the machine shop. Going into 64 Valiant 170. I have a new waterpump on the 170. can I use it on the 225? What about Pullys etc? The damper on the 225 has the damper sandwiched between 2 pullys the 170 has a smaller, narrower single damper/pully. I don't know if it will align with accessories from the 170. The 170 is not yet out of the car.

Yes.
All directly interchangeable.
With the exception of the timing mark location, the '64 and '72 dampers are identical. The extra pulleys (front power steering and rear A/C) are bolted onto the damper.
Yes, it will.
