So, I have a 94 XLT 5.0 2 wheel drive. I'm gonna need to put another engine in her in the next year or so. I bought her a few months ago with 207,000 miles, and right now she's got 213,000. She's got the 5.0 EFI Mustang engine in her right now, and I like the power she's got. What engine should I look for to replace the one I have?

 

The 6.2L

 

Are you asking about the variations in 5.0s? How do you know for sure you have the Mustang 5.0? Those required a different computer from the normal f-150's, and have a different firing order. They also had roller cams, which the others did not. imp

 

My apologies, my roommate typed this for me and she assumed 5.0 always meant Mustang. It's the 5.0 EFI. I already only get about 13mpg, 15 on a REALLY good day, and my concern with putting in a 6.2 is that I will get worse mileage. I'd like to replace it with something the same or better. Since you mentioned it, and I am an infant to Ford trucks, can you tell me a little about the 5.0 variations? Thank you.

 

You can't just drop a 6.2 or any modular motor in there for that matter that easy. It'd take lots of fab, wiring, and everything to get it to fit. That being Said if you want a more efficient motor an yet one that can be had cheap and many harnesses and standalone units are readily available for, go with a 4.6.

It's gonna take some work, custom motor mounts and tranny mount but you could take the motor and trans out of a crown Vic or mustang.

I'm suggesting this because its about the only cost effective motor swap or upgrade you could do vs just putting in another 5.0. A 6.2 or anything like that is so unreasonable, putting a $12k motor in a $3000 truck. If you did that you might as well just buy a newer truck. However you could swap a 4.6 for around $1500 maybe cheaper depending what deals you can find

 

Throw a 5.4 in there and you're set
