Hey aggie you said you beat to 5.4L 4x4s. I take it you have 4x2 so less weight. Bigger is better aggie. The 4.6L is a great engine. Test drove one before I test drove 5.4L. I felt a big difference in power in 5.4L not to say the 4.6L isn't powerful. Remember there is no replacement for displacement. Oh yeah do you have 5 speed?

Oppps...wrong tread... I am looking for advance mental disorders..you know, like dreaming that Ford is building the trucks with Toyota engines.
But anyway, mine is a 5.4 and I am very happy for that.

I also had a dream. I dreamed that I have the correct radiator and guess what. This dream may come true. In a 2001 Silverado.

The 4.6L engine has an aluminum upper intake manifold. The 5.4L engine has a plastic intake. Also, there should be a sticker on the driver's side valve cover that has the engine serial number, type and displacement - 54 or 46. You might need a flashlight to read it. Good luck.

4.6 or 5.4
I will try an help you barngoddess.
Now tell me, in this dream were you shifting gears and working a clutch? If so, then that would be a 4.6 as the 5.4 only comes with an Auto. Of course, it you dreamed you were driving an Auto then it may have been either so let's move on. Many people don't know this but, there is a Fifty Dollar Bill taped to the back of the 5.4L. (that is the end opposite of where the fan is) All you have to do is reach back there and get it. If it's there you may have a 5.4L or it may mean that your truck was built by an unscrupulous assembly plant worker so let's move on.
I'm sorry your hour is up. Please see the secretary on your way out to schedule your next appointment.
