Tom and All,
I hope you all had a great weekend!
This was the response I got from Rob regarding the aluminum caps on the 3.7s. "All CS3.7’s incorporated an aluminum cap. The earlier versions were anodized black, and there were some cases of the anodizing turning gold in color. The later CS3.7’s incorporated a Black Powder Coat on the caps, which would not change colors. I don’t know the serial number in which this change was made, but it was around the #800 serial number. No sonic issues with either version."
