He's probably laughing because most ford guys have been insisting for years that ohv/ pushrod is dead and we will have to go ohc to compete. Guessing he's laughing because it doesn't look like that now does it?
They don't add cubes because the design of the coyote won't allow it. They are stuck with the cubes they have ( think it can go to 318 or so) So... Rip on us for having more. Simple...
High revving complex engine that has to be revved to the moon and makes less power across the curve until high in the rpm range. Vs a larger cubed less complex design that makes power everywhere. With the option of even more cubes. Sounds like a tough choice.

We're all aware of the ages of the OHC/OHV engine designs (at least those who have researched both), so I don't think we need yet another history lesson on when each was first put into use in a high-volume passenger car. I just thought it was funny that the OP used the word "heritage" in defense of the OHV engines still being produced by GM. GM doesn't do it because of heritage, they do it because they feel it is the most cost-effective yet efficient way to power certain vehicles they produce. And they continue to improve the breed year-after-year.
