What is this hood ?

Its all steel, guess it was a RR hood grafted to 69 hood. Fenders and grill are 69 too, explaining no trim strip. Fuel injected 5.2 magnum stroked to 383 w 4 speed 44re , 12" disks and 17's? hummm. Its only 7 hr drive.

If it steel, it looks good from a distance and suits the car. Whats it look like from underneath?
