I gots a 83 t/a automatic. and my friend has a 86 I think mustang 5.0 stick. Who you think will win? Both cars are stock. I was thinking about asking him to race.

 

Your dead
Thats really all there is too it. Your gonna get killed. I wouldn't race him untill you started some mods. But, go into a little more detail about your cars. Gears, Engine model..etc.

 

I gots L69 motor..190 horse? Im not sure of gears n such. Not much into cars...Im pretty sure his is a 86 gt or something..trunk not hatch if that helps????

 

how long have u had your car

 

sorry to add to what u have already been told but im pretty sure ur gonna get owned i wouldnt race unless u have even some small mods and he is stock but hey the good ol L69 does good so give it a try if ur up to it!:lala:

 

I'd have to say the stang too, sorry.

 

Is the reason he'll beat me cuz its stick? The 5.0 and camaros/T/As basically have the same engine dont they?

 

1986 wasnt a very good year for the Mustang. They had worse intakes and heads than 87+ and even the 85s, and it was the first year for the EFI. These were mid 15 second cars (low 15 with a good driver) but it isnt a GT if it is a trunk car. I think you might get beat but not by too much.

 

hey man ill sell u my 84z l69 5 spd t tops and then you can go whoop his ***

 

I had a friend in highschool with an 86 GT, but was auto. He raced another friend of mine with a stock 92 rs that ran low to mid 16's and lost. I'm gonna say you will win.

 

thx. I looked up torque and hp of rustang...200 horse and about 280 or something like that torque. now the horse isnt much more but then torque is. Will this make much of a difference? And Im wondering also is there a way to tell what size engine it is. Cuz Im pretty sure I got an L69 but could be different.....I do get pretty bad mileage and it seems quite a bit of power when I step into it.

 

Just run him and tell us what happens.

 

Chk your 8th diget on the serial # or just type your # in here https://www.thirdgen.org/newdesign/vin/ and then u will know.

But if your an Auto I would bet your an LG4 as they didnt put the L69 to an auto in that year.


83 Trans Am (M5,A4) LG4 V8 8.6:1 5.0 (305) 150@4000 240@2400 4bbl 3.23 3.73 3.23 ----

83 Trans Am (A4) LU5 V8 9.5:1 5.0 (305) 175@4200 250@2800 CFI ---- ---- 2.93 3.23

83 Trans Am (M5) L69 V8 9.5:1 5.0 (305) 190@4800 240@3200 4bbl HO 3.73 ---- ---- ----

Engine codes: (8th digit of VIN)

 

im sory to say but if ur and lg4 ur gonna lose misserably....giver a run and see how it goes. thas all i can tell ya. good luck

 

Honestly I am almost positive its an L69. I checked it before. thats how I know...But ill double check it after for u guys. It may even be bigger then a 305 judging by power but I have no way to tell.

 

Dude there is no bigger for your car stock.

Are the Engine options for your year m8. And note listed with the L69 is no Auto trany. They came with Auto's in 84 not 83.

Give us the 8th diget in your serial # and I'll tell u what motor u had stock.

Basicaly is your 8th diget an H or not?

 

86 was a down year for the Mustang as well as the detuned port of the F-Body.

But 85 was the first year for EFI. Had a buddy back then had a black GT, only available with the automatic. That car was a dog. '85 HO carbed cars were much faster.

 

If your car is completely stock, then you don't have an L69. Maybe your tranny was changed or maybe your engine was changed, but otherwise you probably have an LG4 or an LU5. So if you have an LG4 or LU5, then it won't be very close. LU5 power numbers can often throw you off, because it was just as slow as the LG4. They weren't designed too well. He weighs less than you and has more power. I'd race him just for fun, but its up to you. Don't be stupid and bet anything, just have fun at the track. Get a good launch, and do your best. And by the way, since you are a member of this board, I would suggest finding out everything about your car. After all it is yours and all the info is on here.

JUST RACE HIM!!!

 

sorry guys it is a code H. It really doesnt feel like Im only getting 150 horsepower though....I used to have a 86 Monte SS and this car seems more powerful then that. I dont know how I thought it was a L69 maybe some site tricked me or something.

As for what my cars got--Since your wondering. Its Non Tilt Non Power locks/etc--Non A/C--Its got the wheels with the chrome around the sides. Someone said they are GTA wheels???They have chroms stars in the middle. Also the Tranny was rebuit, and A new exhaust system. Im guessing from the cat-back. Anyway...thats all I can think of. Let me know if theres anything else you wanna know.

Call me crazy but I dont think its the stock engine, Ive owned a 85 Z28,,,a 86 Monte SS, a 87 Cutlass S. and this car. And when my car is running in good condition I can launch from idle and make the tires squeel pretty loud. It also is very mean sounding when I floor it or even casual driving. If theres any kind of picture I can take of the engine or anything to tell what size it is please let me know. Lemme see if this works I got a few pics of the car.
(edit) I also get 12 mpg avergage. Does that seem about right? I think it sucks. I hate it. Im thinking about getting a 260 78 cutlass or something or maybe just a rebuilt 350..maybe rebuilt motor get better mileage? How about a 2 barrel VS 4 barrel whats the difference????

Im rambling on I gotta stop....Thx guys for the help.

NoProblem now go race

Looking at your pics, u dont have the dual snorkle so that first sign its an LG4, your dipsticks on the pass side so its a newer block (my 69 block is on the drivers side ) U got cast heads and cast intake, well basicaly your engine look's totaly stock. Could have cam and port work done but then theres usaly abit more visable mods done too.

Go race him and see how u do, u never know he might not know how to drive that car or it could be running bad.

 

Ya I dont think the mustang really drives too well. The previous owner to him which is also a good friend sold it to him put alot of money into it. Like he had to replace the whole rear end, and TONS of more stuff just to get it to run properly. I dont think the current owner really drives too well either since hes driven a v6 automatic for like the past few years before this car. And he beat the living **** outta that car. When I feel like it Ill ask him to race. I just really wanted to know what you guys thought. Always like some good advice.

Nate

 

I think MODS :P then go race him If u want some tips on what mods feel free to PM me.

This isnt the right section for them modification posts but there is a carb section and Tech / General Engine section for Q's too.

 

Definitely an LG4. What engine did your 85 Z have? Was it fuel injection? Was it carbed too? If it was the TPI 305 in the 85, then there is definitely work done to your car because that 85 should be a lot faster. If both are carbed, then they should drive the same. Get some headers and y-pipe. You'll like those

~Matt

 

My Z28 had a carburator too...I got rid of it cuz at the time I had it it needed a new tranny and exhaust and wasnt working fulltime to pay for it. As for the Monte..It was rusted all over the place and the starter and battery died so I sold the rims and junked it. As for the Cutlass, It got stolen that was prolly my fav out of all my cars. I like G-bodies alot. I was thinking about trying to sell my car for either 1500 without subs or 2000 with the subs, and getting a loan and buying either a Grand National or a 4-4-2..Anyway before I sell my car Ill race him and let you guys know how it went. Expect more rambling in this thread. Like many of you I like to talk about cars. But unlike you. I hate working on them.....

Not saying he will win or anything, but i beat an 83 Mustang wtih a 79 302 (the guy didn't even know what the motor was out of)
I have an 87 Cutlass with stock LG4 with cheap true duals and 3.73 open rear end. I beat his r/t but then i spun really bad through first and second gear

me:16.6@87mph
him:16.3@84mph

i think if I'd gotten traction (i didn't even do a burnout) i would have run a low 16.
my first time at the track i ran a 16.4 with better traction but it was shifting early and i wasn't brave enough to manually shift with the column shifter yet. it was also a lot hotter out and i needed to advance my timing and run 94 octane.

 

wow I had a cutlass with the stock 307 and i could never spin the tires at all. It was weird. I couldnt even brakestand the damn thing. but ya on my trans am I squeel the tires in 1st i dunno if i do in 2nd though...Doesnt it suck with that shifter on the column..Uhhh I hate those!

 

That sucks. I had a '83 Cutlass with a 231 V6 and I could spin the right rear tire. I can squeal the right rear tire in my Town Car! 229 lbs. ft of torque to the pavement!!!

 

The 307 will spin the tires from a stop if its running right. I know a guy with a Caprice with a 307 with over 200k on it and it will light up, not fast but it will light up. I also had an 83 Grand Prix with a 231 and it would brake torque but wouldn't spin from a stop, it just bogged.

Ya the column shifter sucks, can't decide if my christmas present should be a racing shifter or some headers for the ol LG4. oh ya and my car always squeals into second gear.

 

you could always get a ratchet shifter for it!

I also found out that the mustang that I was gonna race is on the shelf. His friend said he needed some plastic or something for it? There seems to be always something wrong with it. I doubt itll even be running right when we race. LOL

Also if anyone can answer my heater core question and plug question both I think are in North east forum...I would appreciate some help.

Nate

 

Ya i want a ratchet shifter for it, but its either that or headers for christmas and i can't decide. I wonder which one would be easier to install? I have to remove the air conditioning to put the headers in. The ones that fit with ac are really expensive so i'm taking it out.

 

Get the headers. They will actually make you faster.

 

^Thats what i was leaning towards.
oh ya btw the 307 Cutlass usually run a mid 18 in teh 1/4. a 231 g body is like a 19 or 20 second car. :-)
i think my cutlass woulda ran a low 17 or high 16 with the 2.73's it had before, does that sound about right?

 

in the tech section they give u tips on tuneing those lg4 carbs, that might help. aslo u could try some free mods like a CAI, if the exhaust was replaced with the stock size then thats also killing u the exhaust on the LG4 is just wrong. get headers, exhaust, high flow cat> that should make a good diffrence. thats if u wanna mod oh and ya that is the stock engine 99.9% sure lol.
good luck!

 

If it's a trunk it's not a GT. GT's have always been hatchbacks.

86GT's are quick little cars. DOn't look at the peak HP number. It's only got 200HP but it's got more power under the curve if you know what i mean. The 79-86 cars are a bit lighter than the 87+ cars plus the short runner intake on the '86 makes a flatter torque curve.

EIther way, he wins.

 

MY 100% stock 86 notch is ALL there. They fall off up top compared to the 87-93 cars but it is quick. My 86 weighs about 300lbs less than 93 GT. I have not driven my 86 much, only a few rips up and down the road sicne it was wrecked when I got it. But it moves, I know it is in the 14's somewhere. Some guys in Corral have gotten mid 14's with dead stock 86 notchbacks. Have to wait and see what I get with mine! I rna 15.54@92 with my 89 LX AOD 2.73, and my 86 is MUCH quicker than that. Heck, my 92 Crown Vic is a high 15 car!! 4000lb beast...hahaha

 

thats pretty sweet. His car is also a 5 speed...Hell I havent raced him yet. But I dont really talk to him much either. And my car isnt running good right now. I gotta take it to the shop on monday to have the choke, timing, spark plugs checked.+whatever else...And if it helps any too his car has a replaced rag top, and tons and I mean tons of diamond steel all over the interior, and floor boards. So maybe he has some extra weight....After my car is running sound and stuff maybe ill race him.
