We would need alot more information to help you properly. First, will it be EFI or carbed?

Basically, if all you want is a carbed 351, you need 302 mounts, you can get old ones that may break easy or get some from chuck. The rest of the wiring is up to you.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

One word: search. this topic has been beaten to death.

With that said...
You can use your k, but as mentioned, you'll need mounts AND the rare, '86-'88 only brackets, OR you can use Chuck's mounts, which I'd recommend, as the 4 sets of mount brackets I've now came across have all been cracked on one or the other (and in one case, both.)

I'd guess the W in the '83 is probably carbed, right?

What about transmission? Manual? Auto?
If the TC is a stick,  I'd suggest using a V8 spec T5, instead of the 2.3 T5, if you want to use first gear...

If going with efi, you'll need to locate an '88 ONLY harness, for the easiest work, as it will directly interface with existing car wiring/connectors. Mustang engine harnesses will NOT work w/o some repinning and otherwise.

Sorry if I come off as an ass about this, but I've had a goal for an efi Windsor Tbird, and if you think it's cheap or easy, well....let me tell ya, it's neither ;)

Good luck!:D

No harness from any year Bird, Stang or '36 Hudson is a direct swap into a '87 or '88 TC... Anything you get will require repinning the connectors...

I thought there was a company that did that harness repinning to work with the ride control and abs? Ed Marsh I think?

Got it. Windsor fox. Are they still arround?

Yes they had one but were about $700 when I last checked...

All my wiring and necessary parts to install the 5.0 came from a $100 '87 Sport parts car... That car had almost everything new, including batt, radiator, starter, alt etc... Even had new tires on 10 hole Stang wheels... For $700, I'd have had a pound of wiring... That came close to buying my Trick Flow heads(OK within $250)...

Ouch. Thats a spicy meatball. I guess if you are bad at wiring, that is not a bad price.

So you have a turbocoupe with a swapped 302 or a sport with Turbocoupe clothing? If it was a turbocoupe, how was the wiring on that. Does everything but the fuel selector work?

My car is a TC and yes everything is functional, cepting the fuel switch(I have used it for a throttle control) and the WOT function to switch the suspension to firm if in auto... Both were controlled by the 2.3 EEC and of course the 5.0 puter doesn't have these functions... Possibly could use the A/C cutout relay to operate the suspension, but it stays in firm unless I'm at the race track, so isn't of value to me...

Wiring wasn't a issue for me, as I repaired electronics(TV)for a living, at least when the stuff was repairable... Figure at the least on having a '87-'88 EVTM available if you plan such a swap...

I was scanning the newly installed 5.0 system for codes one evening and impressed the Hell out of one of my buddies that wandered by...

Was yet to install the engine...

Interseting. I do have a EVTM for a 87 I think . Are the years the same or do I need a 88 EVTM?

If there is any difference in the '87 & '88 TC other than the alternator, I don't know what it would be... The harnesses are slightly different between years on the 5.0 and several differences on the 3.8 as it changed from CFI to EFI...

I have a '87 harness in mine...

I guess it's a good thing that I moseyed into this thread...

Yes, I make them myself.

You can see a pic HERE

They come ready to bolt-in.  No extra parts needed.

They run $175/shipped.
