hi, i just have another of my infrequent question you are so helpful with. i am thinking of a resto-mod on a '68.
is there differences in the 86 - 93 5.0l motors in the mustangs? do other cars have the same/similar motor/emc's? some people uss the irs rear eds for the early 90's t-bird also, right? did the t-bird come with the 5.0l?
Yes there are differences internally to the motor. Mustangs came with the
5.0 HO which is true roller motor, the cam and valve specs are different, the rocker are different, the pressure settings and diameters of the fuel nozzles are different, and they require a different computer to run correctly. There are numerous articles on the internet talking about this swap. Do you want to keep the Fuel injection or do you want to carb the car? AOD/C4 4 speed vs 5 speed. yes the t-bird had 5.0 through 93 however it is not the HO motor.post 94 cougars and t-birds got the 4.6 putting the IRS in an early car requires some extensive suspension mods as this rear is a four link set up with coil overs' and your car is a frame rail mounted leaf spring set up.
Yes it did. Whether there were HOs and non-HOs I don't know first hand but I know for a fact that HO Thunderbirds and Cougars exist, I know two people that had them. If the guy says he had one, then he should know whether his particular car had a right hand or a left hand 5.0
Ya it was a 5.0 HO and my car had more than 155 HP, LOL
Sorry I can't remember the VIN, I don't make a habit of memorizing them anyway. Here is an 1992 for sale, why don't you go buy it and then you will know that there were 5.0 HO's in Thunderbirds!
My 91 XR7 is a 5.0L HO. Only offered the V6 or 5.0L HO in the Cougars for '91. Don't know about the t-birds but these cars were almost exactly the same mechanically for that series.
in 1993 there were only 2 engine options for the cougar regardless of trim package the 3.8 v-6 and the sefi 5.0

the thunderbird had a wider range of engine choices including the 3.8 efi and a supercharged V-6. The 5.0 HO used from 91-93 was infact a detuned version of the HO used in the mustangs it was rated at 200 HP..in 1994 all t-bird v-8 were the 4.6 mod motors in the SOHC configuration
That 200hp 5.0L listed *IS* the HO engine for the MN12, the standard 5.0L (155hp) wasn't offered in the cats. I'm not sure if that is what you're saying below
I don't GAF about VINs. And both cars are long sold. I am highly knowledgeable about the differences having owned both a Marquis and a Mustang and I know 100% for a fact that this 92 model Cougar had a 5.0 HO in it AND had monikers on the sides of the car on the molding that distinctly said HO. You can argue with me all you want but that doesn't change the fact that these two cars existed.
I can't stand doing other peoples home work...
"1992 Mercury Cougar: The 1992 XR7 hit the showrooms with new alloy wheels and a freshened interior that includes new seat and door trim. In addition, the parking brake is now activated by a floor-mounted pedal instead of a console-mounted lever. To mark the 25th anniversary of the Cougar a special LS model arrives midyear, equipped with a distinctive monochromatic color scheme, the H.O. 5.0-liter V8, BBS aluminum wheels, and special trim."
If you want to convert it to a carb, it doesn't matter too much.
85 and up cars had roller cams. Trucks got the rollers later. Mustangs and trucks had the good heads. There's is nothing special about Mustang blocks that make them more desirable. The firing order is determined by the cam you choose. HO is something you stick on your fender or model in the basement.
