Such a shame. They looked fast just sitting still.
86 IROC Z commercial.

A Toyota pickup could beat a Fox-body Mustang? Or are you talking about beating a 305 Camaro?
I had a 90 Mustang GT and if I remember correctly it ran a 14.5 or 14.6 stock at 96 or 97 mph. I’ve probably still got the time slips somewhere. This would’ve been 1998 when I was in high school. Definitely didn’t have any issues with 3rd gen F-bodies.
Both. Truck was 190 hp according to the place that helped me with it., 5 speed and 4.35 gears. I don't think those mustangs were that fast. I used to beat them with my duster that ran consistent 15:00's.
Little truck sounded like this one.

That engine sounds great but I don’t think a carb, header and cam are adding 90-100hp to a 90-97 hp engine.
We surfaced the head,ported,etc. They had built another in the past and said that's what it did. Mine would eat those mustangs with 2.75 axle gears and a carb"d 302 every Friday night

Found this story about the IROC Chevys :

I think it was summer of 1987, well the girl next door to me was going away to Wisconsin with her family and I overheard her say she forgot to do an oil change. I told her, while you are away I will do it. She said ok, she gave me the keys, and then I got the money from her Dad to get some Valvoline 10W-30 motor oil and a Lee Oil Filter. It was an 86 Iroc Z, so I did the oil change and everything, so it went well.
So, she and her family came back about 2 weeks later, so I am over there for dinner, and she says thanks for changing her oil. Then she says, but my car now has 500 more miles on it now since I gave you the keys, what do you have to say.
I told her, it is always better to change the oil when the engine is hot as opposed to being cold. Everyone was laughing, but I had a great time driving the car and I did not do anything stupid while I was driving the car.

The carb'd cars were slower (that's pre-86), the EFI cars were pretty quick for the period. 87-93 were 14's on street tires, some of them into the 13's (easier with a notch) and trapping high 90's mph-wise and that's with the stock 2.73 or 3.08 gears (GT).
As I mentioned earlier, mine fat GT with like 150,000 miles on it trapped 99Mph with nothing more than exhaust and ran 13.8 @ 101Mph with some UD pulleys, an aluminum DS and an electric fan. And that was the heaviest combo (GT T-Top) behind the convertible.

Yep, that sounds right. Some were a bit quicker, some a bit slower, but that's pretty typical, mid to high 90's trap, mid 14 second ET.
IMO, 1986(not '82-'85) was the real year of domestic engines starting to make their performance comeback. When the GM cars went to Tuned Port Injection(compared to CrossFire) and the Mustang offered EFI(compared to carb or TBI) as well. I mean, some prior carb'd engines did better than their EFI versions but not many. Then things just got better and here we are today. 
The carb and TBI stuff from both GM and Ford were mostly in the 16+ times, there were a few that could do better but not much. I had an 84 Z28 with the LG4 before my 94 Z28 that had a whopping 150 HP and auto as well, so slow was definitely the speed it went. It was what I could afford at the time, ended up being totaled in a wreck because someone pulled out in front of me. Saved the insurance money from that and my job to get my 94 Z28 the week after I turned 18.
Most of the 86+ Foxes were right around 15 stock, especially the autos since Fords AOD transmission had some weird shifting going on for some reason. The manuals could be a little faster. LB9 manuals and L98 350 Camaro were right in the middle of the 14s, typically 14.4-14.7 stock. Both could be put into the high 13s with a few decent mods, which is why the Fox was such great platform for the time as it was cheap to start and the mods were cheap as well.
Oh, the doors are definitely heavy, there are rattles, the Ttops leak, and the paint definitely wasn't the best. Most of the 3rd gens actually used the 9 bolt rear end though, which is a better rear end as far as quality goes but it was made in Australia so getting parts for it can be a pain. My 89 as the 9 bolt with the 2.77 gear, I'd like to bring it up to a 3.70 or so but the parts are just so expensive as they all pretty much have to be shipped from down under. The wiring is definitely not for the faint of heart, I spent an entire afternoon building a custom wiring harness for my ECM swap and if you don't know exactly what wire is what you will end up with a lot of problems.

I worked for Chevrolet and later Pontiac dealer in this era. The chevy dealer was on south side of Atlanta. I am not joking not one day at work went by that at least one F body was brought in on the back of a wrecker at some level of stolen/recovered/stripped. Not even RS were safe but most were Z28 or IROC-Z.
I sorta wanted one back then...
I would rather have a Nice GN/T-Type or GTA though. At the Pontiac dealer the GTA sat a while, it was too expensive an no one really knew what it was at that time I think we only got a few.
Ive driven an iron duke Camaro, it wasn't good...

No it definitely wasn't. A guy I knew with an 88 auto did some weird shifting thing where he would start in 1st, shift to 2nd during launch, shift back to 1st, then slam it up to 3rd after about half way down the track. I have no clue how he figured this one out but it did seem to get him to the high 14s. I can't imagine it was good for the transmission though. The 700R4 isn't the greatest transmission in the racing world but at least in my 89 IROCZ all I have to go is go from 1 to 2 to D and it will hold the revs until I move to the next gear. Can pull right around a 14 with the current setup, I'd say the subframe connectors are what really helps though. Huge improvement in both handling and keeping the car straight when going.
There was actually an article in the July 1993 Phrack magazine about how to steal a Camaro:
http://phrack.org/issues/43/20.html
Again, very dependent on the engine and options packages. For 89 the 350 auto could get a 3.23 rear but it was only available on the 1LE package and very few of those were produced. The manuals had better options, which the LB9 305 could get all the way up to a 3.45, another reason it could keep up with the 350 along with the good cam. The 305 LB9 autos were stuck with the high 2.77 gear and a small cam, usually referred to as the "peanut" cam. Really made those cars a lot slower than they could have been.
The cars that got the Iron Duke 4 cylinder had a 4.10 rear gear. Probably to make up for putting an 85 HP engine in these cars.
Mine has the 10 bolt with 3.27:1 gears. If I were wanting to bump HP, I would start with something like this (with Baer brakes):

As a child of the 80's, I didn't care for these cars.
I found them tacky and uncouth (despite what my older brothers/friends said).
My dad was into Volvo's, so I guess that rubbed off on me.
Nothing was cooler than a Saab 900 Turbo/Volvo 242 Turbo/BMW 2002 Turbo
I obviously couldn't afford one, but a kid can always dream!
