73 340-4 speed # matching build !!!!
What a neat car and build story.
I knew it was a late build....
No EGR Temperature Contol Valve hole in firewall.
The change took place on March 15, 1973. The valve was moved to the top tank of the radiator.
340 and 400 4bbls did not have EGR, hence the blank-off plate.
