Because I have a 2v and I don't plan on building the motor to boost it and they are **** for n/a. The 5.0 is cheaper to build for n/a and it will go right into my gt.

There's a lot of things and/or work you'll need to do. k-member, and conversion wiring, etc.

You'd probably be better off going carb'd imo.

JUST GET A 347!!

You can hit low 12s high 11s on a n/a 2v set up right.

it might be cheaper to build, but to get to the point of building is expensive

I have a aftermarket k member right now and the 5.0 I'm getting is in good condition but it's a convertible and I hate verts. I've read a lot about the 5.0 an everyone seems to agree they're better for n/a an a lot cheaper to build then a 4.6 2v, I have a 351w I was planning to put in but that's later down the road. My 2v is slowly taking a **** so in the mean time I wanna drop the 5.0 in.

Looks like you've already made up your mind, do it and take pics!!!

you can start by researching different forums and websites, get a 5.0 engine manual for specified year, if you're replacing with aftermarket parts on the spot look for the ones that fit and interchange them along the way, you might as well build what you can on the engine while it's out, then proceed with the drop in.

K member, bellhousing if you are using the transmission out of your current Mustang, trans mount if you are swapping the transmission out of the donor car, computer and harness. Also, I know on the 99-04 cars they have a returnless fuel system where as the Fox cars have a return-style system, so to be honest I'm not sure if when sn-95's went from the 5.0 to the 4.6 if they also switched the fuel system or kept the return-style system or had the returnless from the start. Might have to do some research on that and get back to you.

Return fuel system up until 98, 99-04 it's all return less. Just letting you know

No it won't, t45 has a different bolt pattern and the bellhousings are integrated like an auto.

You also need to swap the ENTIRE fuel system from your 5.0 car into your 98 including the tank, rails, lines etc... The ENTIRE wiring harness needs swapped from the ECU to the underdash to the engine harness to the body harness. Also obviously will need to swap the electronics, clusters, probably some other stuff too. What else... Well obviously a good T-5 for your trans and I'm forgetting a bunch more.

Really your BEST option is to sell both cars and buy a clean 5.0 and just go from there. Also it is not really any more money to build a 351 based motor starting from scratch.

Also if you live in an emissions state you are going to have a hell of a time getting through inspection with an OBDII car and an OBDI system in it. Unless you converted to an Explorer setup but that's even MORE headaches and totally not worth it.

Like I said, just sell both and buy a clean running 5.0 and don't mess with the swap. What exactly is wrong with the 5.0 you have besides it being a vert anyway?

Why do I have to change the gas tank? I can understand fuel rails but why all of it...I can pick up a used t5 cheap. I want the motor in my 98 because I just had it painted and I'm the second owner to the car. No one is going to know I changed the motor so I don't think I'm gunna have to worry about the emissions I live in Florida btw, I don't know when that comes into play either.

You have to change the fuel system because 1998 is a bastard year where they were transitioning to the 99-up stuff. Its a 99 style tank with a one off return system, 98 specific fuel rails etc.. etc...

And still from personal experience you are going to spend more money doing this swap and go through more trouble/headaches than if you just sold the 5.0 and modded the 2V. You do realize that if you just do a PI swap and a set of cams/tune you'll be over 300whp right? I agree the 5.0 is a better platform when you are staying NA but only if you are going 351. Basic 5.0 vs 4.6 really is a wash. When you start spending the $$$ its also going to equal out to about the same whether you go built boosted 4.6L or a stroked 408w. I've been to this rodeo many times for many years lol.
