i had a run in with a guy last night with a new edge gt. it had some sick body kit on it, looked like a roush, and the exhaust came out on either side underneath the doors. We did two 3rd gear pulls from about 70 and i put a couple cars on him it seemed like, but i couldn't really be too sure, might've been a bit more or less. anyways, i asked him what he had and he said he has a 5.4 motor? i thought he said 5.0 but sure enough it was a 5.4. the only thing that i thought was kind of odd was that he said he had it dynoed and it only made 250 rwhp, but it made 330 ft/lb of torque. is that right? thats a ridiculous amount of torque for what it is. i wasn't sure if he meant at the flywheel either, then he told me that his car wasn't tuned . so i might've been in trouble if he was tuned. are alot of people swapping 5.4's into their cars?

he put a truck motor in it?

the only 5.4L people should be putting into these cars should be from a GT500.. so where's the S/C? or did he buy just the gt500 engine from someone who had already sold the stock s/c? There are ofcourse other 5.4L engines..

I saw a 5.4 F150 get dynoed the other day with a whipple on it. It made 350 rwhp. Sounds about right, Miiler.

I think that motor is in the Lightning and Triton trucks....and it's a SOHC version versus the 5.4 DOHC in the GT500.

or it could be the 5.4 DOHC Lincoln Navigator engine. it's a low compression engine, so peak hp wasn't very high, but it's a truck engine. lots of torque.

damn, i bet that truck sounded pretty badass at peak rpms. was it a single cab?

m5miler

that might've been it then. yeah i was confused when he said it was a 5.4, i asked 5.0 and he responded with haha nah man its a 5.4. yeah that explains the torque issue then, those navigators need good amount of torque to help propel it off the line.

the 5.4 out of the 99 cobra-r was also an ok engine.......

A stock SOHC 5.4L could easily make those numbers. The '04/'08 5.4L SOHC found in the F-150 were rated at 300hp and 365ft/lb at the flywheel.

Yes it does. Also remember that trucks have a ton of loss to the rear wheels; HD trans, HD rear axles and heavy wheels and tires.

Exactly. The tires alone on that truck are massive enough to eat up a good bit. Its a long trip from the flywheel to the pavement on those trucks. I found the actual vid. They put up most of their dyno runs.
