RE: C3AE-C cc? |

You're helping us a lot here Travis. Thanks because it's just so strange to see that these heads were used as you've found. An example, I have a '64 390-4V that was a complete and correct engine right out of a '64 Gal. It had the C1AE low performance heads you describe. Did the '63 390 have the dished pistons like '61s? This '64 390 spare I have had flat tops that with the C1AE heads yielded somthing over 10:1(going from memory here). So was Ford trying bump the compression ratio up in '63 while retaining the dished pistons that had been yielding 9.5:1? And yes, the heads we are looking at have the rounded combustion chamber that looks just like the c-chamber of a guaranteed genuine '63 406/405 head that is factory machined for spring cups. We know that head is 406 correct. It's our theory that these C3AE-C '63 390 - 4V heads are great candidates for the larger '27/'28 valves and machining for spring cups - there you go....A good set of HP heads if you want decent compression. |
