[Mr 5 0]

My User Name indicates my preference but I have to say this: It doesn't matter if the pushrod 5.0 is superior to the 4.6 OHC engine or not, the fact that Ford is churning out tens of thousands of 4.6 V-8's in their various lines and not 5.0 V-8's is what will cause the modular 4.6 to dominate, eventually. It's as much a matter of both math and marketing as anything else.

I can't offer a time-frame but the 4.6 will dominate simply because it'll be the only Ford V-8 engine readily available. Like it or not, pushrod technology will slowly become a distant second in buyer preference as young guys grow up knowing only OHC tech and see the 5.0 as antique, just as another generation saw the Ford flathead V-8 - which dominated during the late 1940's - early '50's Hot Rod era - until the Chevy V-8 was introduced in '55. Then, within a few years, flatheads were abandoned by anyone looking for real power.

The 5.0 won't 'die' like the flathead, it'll still be seen as there are zillions still around but eventually they will just age out of the market and while you may still see a few 5.0's powering 'old' Mustangs and kit cars in 25 years, they'll be considered ancient and out-of-date. Guaranteed.

Frankly, right now, I still prefer my 5.0 for a multitude of reasons but I have no illusions that it will still be around in another decade and I've adjusted to the fact that no matter how much I like the 5.0 and whatever the current shortcomings of 4.6 the modular V-8 will be powering my next Mustang.

Of course, I intend to hang on to my 5.0 powered LX quite a few more years before I surrender to 'progress' and a 4.6. Hopefully, by then they'll have improved even more, aftermarket parts will be plentiful and the factory-stock 'Stangs will be running low 13's all day.

I can live with that.
