I Want It, But How Much Will It Cost?

I don't think it's fair to bring up pump gas as the 5.4l is out of a street-legal vehicle and is designed to run on pump gas as well. As for the HP numbers you've seen out of a 351W, at what rpm?
The 5.4l is all about low-range rpm usage, its torque and HP are all available big-time low-down in the tach. I'm guessing if you wound up a 351W with sufficiently flowing heads and intake and carb, that yes, you could get the big numbers...would you want to run that screamer on the street? I don't think so.

As for the 5.4l available as a crate engine. I'd like to see it too, especially if they could do it for a reasonable dollar figure. I wonder how they'd handle the computer issue though as it is designed to use a unique Motorala PowerPC-based ECM that is unlike any other Ford ECM.

More power to Ford if they do it.

"As for the HP numbers you've seen out of a 351W, at what rpm?"
over 500 ft/lbs from 2500 rpm up


"I'm guessing if you wound up a 351W with sufficiently flowing heads and intake and carb, that yes, you could get the big numbers...would you want to run that screamer on the street? I don't think so."

Then you are wrong. Idles ike a champ at 850, runs cool, plenty of low end, peak HP in the 6200 range


NOTE: when I say 351W, I am including strokers built on that platform as well.
