RE:C3AE-C heads?
By McQ - 12/26/2003 6:56:01 PM; IP 65.176.105.175
That '63 'bird engine may have the 1963 only 390-4V heads - the C3AE-6090-C. These heads seem to have been used only in '63 for the 390-4V. They have a smaller CC chamber than the C1AE and the C4AE, C6AE, etc.

The C3AE-C head was also the head used on the tri-power 406 for early '63. However when bolted on the 406 at the factory, they were machined with valve spring cups and larger valves.

The C3AE-C head provided a compression ratio bump to the '63 390-4V over the '61-'62. This with the same dished pistons that were used in the 390 for '61-'63.

I'm telling you all of this because I think it would be worth your time & money to pull those heads from that old 'bird if they're still there. They would make great heads to run with a set of standard 390-2V pistons. I would recommend installing 2.09/1.66 CJ/lo-riser valves along with the minimum pocket porting work that should go with these larger vavles. The taller intake ports should match up nicely with the 427 intake you want to run.

I'm not exactly sure which lo-riser 427 intake you mean but if it is a 427 intake I would not run it with the C7AE heads you may have on the '67 Merc 390-2V. Look at the intake ports on the Merc 390 heads.....cute little shorties aren't they? Look at the intake runner ports on the 427 intake.....not a good match.
This thread, so far...
