1984 LX Engine and Transmission Swap Questions

Hi guys, new here, but not new to Fords or projects.

Long story short, my daily/project at the moment is a 2006 Focus ST, cleanly modified, and even installed a GT28R setup running 12psi.

But that's beside the point.

I was referred to this forum by a buddy who told me you guys all know your stuff pretty well, and was hoping you could answer a few questions. If all goes well, I'll stick around for quite some time during this project.

I have a 1984 LX 5.0 convertible, and I am unfortunate enough to have an automatic transmission along with it.

The automatic finally gave out at the end of last year, and this summer, my dad and I need a project as usual.

We are budgeted around $5,000 to do a complete motor and transmission swap, and would love to have something like a crate motor that would make some great power right out of the box. Keeping it in the 5.0 family would be ideal.

My Mustang knowledge is pretty slim, so I would love to hear some suggestions about the following:

-What motor should we go with?
-Where do we find a motor?
-What transmission and where to find it?
-Necessary supporting modifications?

thanks for sharing your knowledge.

Depends on how many horseys u want. I say buy an old motor from a junkyard rebuild it gt40heads and some bboltons and rebuild the aod and spent the rest on booze and hoars. But that's just me:hihi:
A junkyard 96-01 Explorer 5.0 with a fox Mustang t5 manual or automatic will get u 300 HP flywheem then spend the rest of the money on supporting mods... FYI b sure to swap the Cam and valve springs for better ones

What's the HP goal?
A stock 5.0 block is only good for 400-550 hp range. If you will be under that you have many options:
Stock short block with good heads
Stock long lock with forced induction.
Strock the 302 to 347
Or a 351w is a great upgrade if you won't big power on budget

The swap from an aod (aotomatic) to a 5 speed isn't too hard. There is a thread in the stickies on it. The T5 is limited on how much power it will hold.

Thanks for the quick responses guys.

As for power, we're actually looking to get some big numbers, hopefully 350-400 or above. crazy power is fine, i'd imagine our budget of 5-6k could buy us something with a blower, perhaps a crate motor?

thanks again for answering my questions.

I was digging through time slips today, and I saw my old 1983 with an "engine swap" ran low nine's at nearly 150 MPH with a single Holley 4 bbl.

More practical though, a set of good aluminum heads, with a good cam grind, good headers, and a good intake and carb would easily get you 350-400 HP and be streetable. You might want to buy a good crate motor. That's the way to go, although they are usually under-cammed.
