I have a 99 f150 with a 5.4 and the motor blew up... Now my question is will I have to put a 5.4 back in it or will a 4.6 work

 

Putting a 4.6 would be possible but stupid. Any 5.4 2v 99+ will work. Going with a 4.6 would be a major downgrade and there is plenty of good 5.4's out there.

 

Yeah... But in my area there hard to come by and when you do find a 5.4 there 1200 dollars or more and wore out.. Guess I will keep looking for a 5.4 though

 

a 4.6 will run forever if maintained. But i agree with jethat. It'd be a downgrade in your situation. Keep looking, check pick and pulls for em too.

 

There are Rebuilders who sell them under 2 grand. I found the one in my truck for about 1200 it only had 40,000 on it. Remember any 2v 99+ will work. Truck Van Explorer expedition. You'll have to swap a few parts but they all work. There still putting the 5.4-2v in the Econoline far as I know.. And Far as I know its a swap..

 

Your going to have to spend a few bucks... it's an engine, and a big one. You should be able to find engines at junkyards, used car parts or craigslist. Check areas near you, you may have to be willing to drive a few hours. Expect to pay about 1000-1800 depending on mileage. Id try and find one with 50-75k for 1400ish. If your patient, you can find better deals. I got mine with only 10k miles for 1400 and that included the rest of the truck which I was able to sell parts off of and make my money back. But it took about 2 months of looking every day to find it.

What area are you in..?

There's a shop in my town that specialized in 5.4 and 4.6 rebuilds. Long blocks are 1600. To me, that is a fair price if the builder is reputable.

Agree with jbrew. Find a lot of stuff there. 6 transmissions, 1 transfer case, 1 9.75 rear axle.

 

When I was looking I found the best deal by actually calling the local JY's not all of them are part of car parts network.
