Is anyone documenting the SPD's to narrow down when engines went from turquoise to blue? This gold GTS is blue, this swinger 340 is turquoise (though it appears the motor may have been apart).
I have a 69 340 that I haven't verified what it came out of (dart/Cuda) and its obviously a turquoise motor. How ever, the 340 swinger I currently have is a late build and I want to paint the original color. Unfortunately the previous owner blasted everything and no original color was left, then he painted it orange...then black. SPD is 709.
