They did not make a 93 4 cylinder Thunderbird and even if it is a 6 cylinder the bolt pattern is metric on the wheels.

If the rear is a 7.5 with "3.55" gears, I'm betting it's an earlier 7.5 Turbo Coupe rear with 3.45 gears.

Your right vinniebird! 3.45 gears, 7.5", Turbo coupe. He said it is four bolt just like mine. Is that right? The guy he bought it from said it might be a bit tall for hwy travel unless I had 16" wheels and that is exactly what I have.

The rear in question came on a car with 15 inch wheels. It'll bolt in and work fine. An 8.8 would be better as they are much stronger than the 7.5. But if you have it, run with it. I used the same rear in my last Bird with no issues at all.

From what I have read here, the 7.5 seems to hold up well for my needs. Even if I put some Edelbrock heads on it, I still won't be near 300 HP. So, I should be alright. I guess I might save a few lb's going from stock cast iron exhaust manifolds to shorty's (a little more weight off the front). I have also read that they don't give you much HP in return..maybe 3HP? That's ok, it all adds up. After all I have been driving a car with maybe 120HP for several years now. This should be different.

Edelbrock heads are going to make more than 300 HP at the flywheel. I've got Edelbrock Performers on my Thunderbird and based on weight and 1/4 mile e.t. the engine is making around 330hp at the flywheel (about 265 at the wheels, assuming a 20%ish drivetrain loss). This is with a mild Comp roller cam and an unported GT40 intake. Porting the intake or swapping to a better flowing intake would boost power even more. Even with GT40X heads, stock HO cam, and a GT40 intake the engine shouldn't have a problem making over 300+hp at the flywheel.

I'm running the factory 7.5" rear in my Thunderbird with a 3.73 gear and a Traction-Lok. It's been fine so far. I haven't run sticky tires (drag radials or slicks) as I figure I would run the chance of breaking the differential. I do have a kind of rare 8.8" rear from an 88 Cougar XR7 in the garage for when I break the 7.5" rear ;).

Some one up stairs is sure watching over me! It seems like every thing I need has just dropped into my hands! I might have to wait a while before I get the heads on, I still need to go through emissions here before I take the car to my new house. Also, I'm sure the heads will void the 3 year warranty. I probably won't wait that long, but I do want to run the car as is for a while just to get a feel for it. I'm really excited about getting that rear axle put in! It's like a full package now. Going from 2.75 to 3.45 w/ (is mine traction lock?), that should really sharpen the nails on my Cat. I worked at one place 26+ years buying old cars to fix up when I retired, not realizing I would have forgotten half of what I thought I knew about cars and be half brain dead (my memory sucks). I'm about to turn "56" this month, this first year of retirement I've spent mostly working on this car. This is the first hot rod I have ever built. I never even imagined that I would be getting upwards of 300HP! Everyone tells me I'm building a "sleeper", the car looks plain Jane on the outside. The one think I will be watching is the ride, I might back off of the Poly. a little. I still have work to do when I move to the country, remove the emission stuff (not my new hi-flow cats), put the shorty's on, new heads, roller rockers, push rods, valve guide plates, studs, and I think that's about it. Then I start with the interior, I already have new gauges to put in.

86cougar,
Sounds like you are knocking the dust of the memory and it is slowly coming back.  One thing you have to remember about EEC-IV fuel injection is that it is not brain surgery like the newer cars.  I like the simplicity and how easy it is to work on once you have messed with it especially if you car converting a car which forces you to understand the system.  By the way, which wheels does the car have on it?

All,
These books are considered by many the bible of Ford EEC fuel injection.  I have the one for the mass air cars and I would suggest that anyone here with fuel injection owns a copy for reference:

Aerocoupe,
                This is the wheels I have on my car. Working on this car from the ground up has made me learn a lot about this car. I started back in May and here in Arizona you pretty much have to crazy to do that, especially during monsoon season. Me, my creeper (no lift), work... get up, wipe off the sweat, work... get up, wipe off the sweat, all day long. I know most of the guys on here are probably thinking "so what's new?" 105-110 degrees is a little rough. Thanks! for the information!

It's hot like that here. We're lucky though.....we only have 85-90% humidity to go along with it. LOL. Keep working. One step at a time.

So I know the car is four lug but what diameter are those wheels? If they are 15's you can keep the sleeper look with some 15x7 ten holes. Use two for the front as is and then get the other two widened to 15x9 or 15x10 for the rear and stuff some 295/50/15's under it...its stock from the side but when you go by they scratch their head a little. There are a few places that do it but these guys in Dallas are used a lot and  good:

You can buy blingin' wheels for about the same but a lot of guys like the old school sleeper look so this is how they get wider wheels.

These are 16" X 8" (I think) wheels that I was told were for racing. Notice the way they are designed to keep the brakes cool. I really do like the stance for "83-88t-Bird Guy's" "83" T-bird. I never even thought about wider tires on the rear of my car. I just went outside to see if these would fit on my "71" LTD convertible, but it has five lug wheels on it. Then I could just by a new set for my Cougar. If my car's stance looks like "83-88t-Bird Guy's" T-bird that would be nice, but it wouldn't look like a sleeper. It would look mean. Darn! now you got me thinking again....

Well, I got my car back yesterday. Right now the car has the 3CW EEC-1V on it. I will probably go with the A9P. I took it over to emissions and
 
HC loaded was 39 (standard is 220),HC idle was 48 (standard is 220),
CO loaded was 00.00 (standard is 1.20), and CO idle was 00.00 (standard is 1.20)

It passed. The car runs like it has a vacuum leak at idle, so we figure it might be either the computer still learning, or I need to bump up the idle due to the under drive pulley set. The engine might have about 50 miles on it by now and I am about to go change the oil and filter being it was running very rich early in it's short life. I think I thru the kid at emissions off when he saw my duel exhaust, but what could he say with my new duel cats. aboard. The car sounds great, not too loud but present when you hit the gas. The transmission is smooth, but I don't really think it is ready to judge just yet. The engine is being pampered and is too new to judge it as well. I can tell I have more power than before. I can see the speedometer climbing, but not a hard pull feel (at most half throttle). It's deceptive.... I really don't know how to describe it, it's like it's more mature. I can't even describe the handling... I taken a few corners to get a feel of this new suspension, and there is no surprises. It still needs a front end alignment and if there is room for improvement, it's the tires. I took my girl for a ride last night. She loved the sound and her eyes got big when I pulled out in traffic a couple of times, then a smile would come to her face (kinda like me). I will post pictures after I wash the car. Thanks!

The guy I bought the 3CW EEC-1V couldn't find an A9 for me so I have been using the 3CW and it seems to be running fine. At idle I will sometimes feel the cam and other times it smooths out. I figured out that on my first tank of gas I got 18.07 MPG. That's with a "87" Mustang HO engine, duel exhaust, under drive pulleys, stage #1 cam, and 19lb. injectors. I even let the car sit at idle and let it warm up for 5-10 minutes before I take it out. that's about .05 MPG better than my stock engine did.

I still need to take it in and have it detailed. Definitely not a show car, just my daily driver.
