Q.

Will larger 429, and 427ci engines be designed, and mass produced in the future, for high performance Mustang variants?

A.

We recently introduced two new V8 engines in 2011, an all-new 5.0-liter for the Mustang and F-150, and a new 6.2-liter V8 that is used in the F-150. The 5.0-liter is rated at 412 horsepower in the Mustang; 360 horsepower in the F-150, while the 6.2-liter has 411 horsepower and a massive 434 lb.-ft. of torque. Both of these engines are more powerful than most of the regular production versions of the classic 427 and 429 engines of the late ’60s and ’70s. Those engines were rated at somewhere between 360 and 400 horsepower. We also have a 650 horsepower* engine coming in a few months for the 2013 Shelby® GT500.® Because of today’s technology, we no longer need very large engines to generate high horsepower. However, if you are interested in a very large engine, we offer a 521 cu.-in. crate motor through Ford Racing. You can look at the engine as well as many other high-performance old-school pushrod engines at http://www.fordracingparts.com/crateengine/main.asp

N. R Thanks, I'll keep this in mind. Nothing I didn't before, but this information is still useful. Guess stupid questions can lead to great answers. :)

N. R Yeah, it's a somewhat ridiculous question. Too bad Ford shot down the one I had about direct injection for the 2015 Mustangs, that was much more reasonable. :(

Kyle R Hard to imagine that happening with a gov't mandate for 54.5 MPG average fuel economy by 2025. I'll be ecstatic if the current 5.0 and 5.8 liter motors can continue being made past 2014.
