How much should a basic 340 rebuild cost?

I wonder what year that is from.

Resurface a v8 head - 1hr : $9.00

That from a 1970 Professional Chilton Labor Guide.
Basic overhaul, then extra charge for the stuff in the frame.
Dealership times were less .

We would give a firm quote with these guides, and most often beat the time significantly, and give the customer a deal.
