Well, I came by my opinion that the 6.2L was designed for the Raptor honestly. Here are a couple of quotations direct from Ford promotional literature circa 2011:
- From a page entitled "2011 Ford F-150 Raptor 6.2-liter V8 Engine" - "Ford's rich racing heritage inspires the
new 6.2-liter V8 engine for the 2011 Ford F-150 SVT Raptor." (emphasis added)
- From
http://media.ford.com/article_print.cfm?article_id=33181 -
--"New for 2011, the Ford F-150 SVT Raptor delivers a standard 6.2-liter V8 engine with class-leading 411 horsepower and 434 lb-ft of torque, powering customers through almost any off-road terrain they encounter."
--"The engine and truck were tested in the Baja 1000 and on a unique desert loop designed to prove out the durability that high-performance, off-road enthusiasts demand."
--"Core features of the
new 6.2-liter engine include cast-iron engine block and four-bolt main bearing caps, aluminum cylinder heads, a single overhead camshaft with roller-rocker shaft drivetrain and dual-equal variable cam timing."
"The 6.2-liter V8 is similar to the engine used in the
all-new 2011 Super Duty,
but features unique tuning and a special cam profile to produce more horsepower and torque."
From an April 27, 2010 Motor Trend article by Angus MacKenzie entitled "First Drive - 2010 Ford F-150 SVT Raptor 6.2" - "
Ford's new 6.2 liter V-8 is the engine the Raptor was always meant to have; the decision to launch with a tuned Triton was made when the engine and truck development programs got six months out of phase."
And very interestingly, there was a Car & Driver road test entitled "2010 Ford F-150 SVT Raptor 6.2 - Road Test" from October 2010 by John Phillips. The report specified 379 cu in, 6210 cc, and documented an observed fuel economy of 16 mpg.
