Congratulations, you got one!
I’m sure you will find items that maybe need attention or upgrading.
That’s the fun of the hobby.
One thing I may suggest is the radiator.
A higher performance engine, such as the “Factory“ 360 HP Tri-Power motor would have come with the larger (thicker 4 core) radiator.
It seems your 66 has the thinner 3 core version.
Also FYI, as always someone installed the valve covers backwards/wrong sides
Good luck and have fun.
Chris.
