So let me guess the torq conv fron my 4.6 expy won't fit the 5.4 fly from the f250...

 

No,totally different.

and the 4.6 romeo fly is diffrent....

 

Only the number of bolts to the crank.

how much do flex plates normally cost from a junk yard...

 

Typically not an item that you can get from a yard. They sell the engines complete with flexplate nowadays,and do not like to pull parts from them. Autozone lists a new one for $54.Dealers shouldn't be much more than that-I'm pretty sure the last one I got at the dealer was around $65. All you need is one for an F150/Expy 4R70W with an 8-bolt crank.

That's not bad where can I get the lower plastic intake from. I can't find anywhere but from dealer for about 400$

 

That's about it-unless you find a yard that has a core engine lying around that they would want to part out.Possibly ebay-I see intakes on there from time to time.

Here's an all-plastic manifold for $125:

Thanks... I've ran into so many problems with this swap I may just wait till 75 dollar engine week at harry's to get the 4.6 from some cv there is plenty cop cars there... I'm tired of this job allready I want to drive how is the 4.6 for towing garbage or can I tow some stuff...

 

I used the pull a 30ft travel trailer that weighed a max of 6500lbs with the '98 F150 in my signature. It had 200K miles on it,and handled it without much fuss.
hehe..here's a pic I shot when pulling that trailer down the interstate on a road trip a couple of years ago...

Lol the dummy oil guage was a little high

 

So would a cv motor go right in the expy

 

It should-just swap the external accessories and the intake,etc. There were 2 different torque converters used on CV's though. One was a 12" and the other was an 11.25" converter,and the flexplates were different between the two. The flexplate for the 12" will fit you truck converter,the 11.25" flexplate will not.
