GT motor assembly was never shared with any car or truck.
In 2007 the Mustang GT500 came out with a similar motor. Displacement was the same, that's where it ended.
Lightening had a 5.4L SOHC motor with an Eaton blower if I'm not mistaken.

Yeap, lightning and all 5.4 trucks from that generation all had iron blocks. No truck or car ever had the aluminum block until the GT500 and it was still not on par with the GT. Its fairly similar to the Cobra R which did have similar heads and aluminum block with nearly 400RWHP N/A back in 2000. But the heads on the GT flow more than even the Cobra R. The only 5.4 DOHC was used on Navigators at the time and they had 52cc combustion chambers and drastically different flow rates and cams.
However, 90% of F150's had forged cranks and all lightnings had forged cranks. Not a big deal, the heads, cam followers, lash adjusters, cams, oiling system, superchager, intercooler, were all vastly different. Unless the Cobra R had a dry sump, I don't think Ford had done that before either.
Consider the 03-04 cobras had forged bottom ends with DOHC, and were 4.6's and the Lightnings were 5.4 with SOHC and ended production in 04, I kind of expected FORD to do something with a high output 5.4 with the works. They did just that and are some out there making 1200-1800 rwhp with the ricardo trans stock.
