You're right of course. $450 was for the basic rebuild. I've forgotten what I paid for my 1958 convertible but that sounds about right. I've still got the build sheet and the transaxle. It's perched on the tongue of my Airstream.
I can't find anything this morning about the OCF. The State fairgrounds (in Salem) is an evacuation center. But the Country Fair retreated into the cloud this year:

The Holiday Ranch fire itself is East of I-5.
edit:
Phoenix, Talent, Blue River, Vida and Detroit are gone.
