I have a 2004 F150 heritage (old style). I bought it off a guy with a bad motor and the truck only has 56,000 miles on it. They guy claimed he couldn't find a motor for it because of it being a "heritage''. has anyone ran into this? what 4.6 can i get to work in this truck? what will need inter changed?

 

Hi should be anything 2004 heritage back to 1999 i beleive they put power improved heads on them.

 

The only thing I see different in the interchange book, 8 bolt flywheel and 6 bolt flywheel. Also a "Romeo".

 

There is a rule about these motors that goes like this; take it out and apart to see what's there before ordering any parts.
There are too many changes over the years and during production runs from different plants that can trip you up..
Basically all you need is a new or rebuilt short block with the right crank bolt pattern to fit your flywheel so the total balance is maintained then put the rest of your parts on it so everything is there as before.
Good luck.

 

Thanks for the responses!

 

Do you know what the problem is with the "bad motor"?
You never know, might not need much to repair.

 

i will have it. They guy never brought with the truck. i am actually curious as to what it wrong with it myself. it only has 53,000 miles on it. so yeah i might be able to fix it.

 

Look at the 8th digit of the VIN. '6' = Windsor engine. 'W' = Romeo engine. And for what it's worth, those engines are a dime a dozen. You can source that engine from MANY Ford vehicles of that year, that will fit.

 

that's good news! guy i bought the truck off of said it had to 04 heritage only. i thought id check it out. i just want to be able to go buy a motor and drop it in and done. thanks

 

so i found a 04 new style f150, it's a Romeo just like my 04 old style. what all do i have to change?

 

I didn't understand the question. Do you mean you found a donor engine, as in one from an '04 NEW (at the time) body style F-150? If yes, then just strip it down to the long block, and bolt on everything that is specific to your '04 and you're good to go.

 

I just found an 03 Windsor motor. Will that work? I know they are diff. I don't want to buy it and it won't work

 

Sorry about that. I thought the truck I was going to look at was a new body style with a 4.6 ended up being an 03 with a Windsor. Good sounding motor. I'll have everything to drop in mine.
