Anyone know the weight differnce between the 4.6 and 5.4? friend is looking at turning his 03 ranger into a pre-runner, and was going to drop a 4.6 in it but will go with the 5.4 if the weight differnce isnt too much

I don't know, but I doubt that it can much.
The difference between a 4.6 iron and aluminum block is just 75#.

I might be wrong but my understanding was that the block of the 4.6 and the 5.4 was one in the same. It is just that the 5.4 has a bigger stroke volume per cylinder making the increase in liters and thus more power. Same pistons, just longer stroke of each piston. I could be wrong though but that is what i was told. So the wieght shouldnt be much of a difference at all.

^^^ thats correct atleast to what i know, we were trying to get exact weight but cant find it anywhere, we found each motor going weight them manually lol

The 5.4's deck hieght is like an 1" higher over the 4.6 giving it that extra stroke.

The weights like 10-15lbs diff. IIRC

that's not much of a difference.
