Okay, my friends, I have been put onto another restoration distinction that has to be sorted out, thanks to the sharp eyes of Marv Raguse, the owner of what was once my Gauguin C hardtop. The latest point up for discussion is the probability that from 1957 to 1958 there was a change in the positioning of the spot-welded coil bracket base on the left side valve cover of the 300 C and D motors. The current assumption is this: If you have a 300C or D up through VIN #1585, the bracket is positioned above the letter "E" in the "FIREPOWER" script. This places the coil extremely close to the expanded brake booster. If you have a 300D after VIN #1585, the bracket is positioned above the letter "W" in the "FIREPOWER" script. This places the coil some 2+" away from the expanded brake booster. As far as what the assorted parts books say: LEFT VALVE COVER 1735 780 1957 and 1958 300 motors up through D VIN#1585 1851 720 1957 300 and NYer "power pac" (dual quads, no solid lifters option) motors 1944 626 1958 300 motor after VIN #1585 The parts book indicates there are THREE different valve covers! I don't know what that third variation might be nor is there any way for me to know what #s should be assigned to the two assumptions written out above! Your comments are welcome. What valve cover coil bracket placement is on your C? your D? Any ideas on a third variant? C Wayne For C Questions (The C stands either for this guy is "Crazy for Cs" or "Cs are driving him Crazy".
