Non adjustable rockers? C3AE-C heads .... not always for 6V 406. Just a guess here but I think you have a nice garden variety 390-4V-300 horse. We had quite a discussion about these heads back in late July. I always thought the C3AE-C was nothing but the early 406-tri-power head. Wrong! They were if they were equipped with large valves, 2.08/1.66. However, FoMoCo apparently thought these heads with the standard valves, 2.03/1.55, would be a nice compression bump to the '63 390 which was still being built with the dished pistons. A friend has located three sets lately. We've picked up two of the sets because the c-chamber is 64CC. With the larger valves you have a nice set of HP heads. Also will machine them for spring cups which the 406/405 '63 engine had. Many said the heads are nothing special. I disagree. They have great compression making combustion chambers. They were apparently used only in '63. I've had '64 390 4V enignes and they were either equipped with C1AE or C4AE-G heads. The C3AE-C was a one year deal in my guess/opinion. Again, your 390's non adjustable rockers indicate it's not a HP engine. |
