Ford Mustang GT 390 specs

My Mustang 67 390 did a 11.6 1/4 mile and zero to 60 in 3,9 sek. tuned a bit of course a 470-520 horsepower 😂

Did the GT Mustangs have enough difference for an extra page?

Some sources say that collector cars such as muscle and super cars have "special needs," when technically they are above normal cars in the social spectrum. (Btw, I'm autistic so I have the make-fun-of-special-needs-folk pass 😉)

IMAGINE comparing this

to this

I'm not saying special guys can't get chicks. Some can pull 'em stronger than even most normal guys could. . . but ASDs like me have struggled, whereas Lambos and Fezzas and Maccas and many old classics have gotten 20x as much chicks as a freakin' Prius or Caravan

I honestly think a 1960s Mustang could be a Madonna. Italian inspiration into the American world!

It depends on several factors no one is mentioning. Rear end gear ratio, 4 speed transmission wide or close ratio, automatic transmisssion and finally tire size. Also was the engine stock or modified? In 1970 I had a 67 Cougar Gt with a 390 4 speed wide ratio transmission, 3:25 rear axle ratio, J 60 x 15 tires on the rear. I was running Hooker super comp long tube headers, Edelbrock Streetmaster intake, Holley 780 CFM carb, stock heads and pistons, and a NAPA super performer hydraulic cam. The Cougar would top out at 140 MPH at 5800 RPM. I watched the round stock speedometer go past 120 and on around to zero again. I know that is not scientifically official, but that is what the speedometer was indicating. Also the steering was very light with all of that air lifting the car.

I have to chime in here with an all stock, 67' S code, 4 spd coupe that I owned in 1972., & If I remember correctly,it had 389 rear end, H-70's on the rear & F-70's on the front. Fact,my best time was 12.?sec,1/4 M, @ 113 mph. I know ! I should have my head examined for letting it go way back when. I'd give anything to find another like it.

To John Gialanella: My 67' - 390 - Holly Dual Line would to 130 mph.

I believe Phil Norton saying 105 top speed for the 390 S. I would believe the 1968 Mustang 428 Cobra or super cobra jet can do 130 MPH top speed, but not a 390. The 390 was a good engine, but not High Performance like the 427, 428, or the 429 Lima engines which were like the BB Chevy engines with semi Hemi cylinder I have owned both 396 (402 CID ) 1970 Camaro's. The l-78 (375 HP) and the L-34 (350 HP) and loved them. But I would also have liked to own a 1968 Mustang 428 Super cobra Jet, but they are very expensive.

I had to kind of use my tach. to judge my speed in my 390 Fastback Mustang. This was in 1969. I could swear that I was golng damn close to 130 MPH. One time I had three passengers in the car and I was able to get it up to 120 MPH . I backed off for some reason? What little I knew about cars back then and the overall condition of that car, God help me. Come to think of it, I did the same thing with my third car a 1971 Cuda 340. Using the tach. and all.

I owned a 67. Speed to RPM ratio in 4th was 2 to 1. 1,000 RPM got you 20 MPH, 3,000 RPM got you 60 MPH. The torque curve dropped off pretty steep before 5,000 which limited the top RPM in 4th to about 5,500. 5,500 RPM in 4th got you 110 MPH. On a good day, cool and high humidity it would see 115 and that was about all it could get.
In 1968 I raced a Mach One. From a dead stop I could pull him by almost two car lengths. When mine topped out he would blow by me pretty fast. I think his topped at 130.

I owned a 68 GT 390 and there isn't a chance in hell that top speed was 130. It was more than that, and the quarter times were limited by the inability to get the heavy car moving. Mine weighed 3850 and would spin through second gear into 3rd with the C6 automatic it had. Very fun and powerful car. I know that horsepower for these cars used to read 345, I don't know how it has changed.

Wildly optimistic powe and performance claims; top speed was 105 mph, according to road tests at the time.

I just watched "Bullit" again. Very realistic chase scene in and around San Francisco California. The footage was very authentic looking and makes one wonder if all the other cars were driven by extras, or if some were real unpaid civilians. Both the Mustang and the Charger showed very good handling, especially given the bias ply tires available in 1968.

This is Mustang GT 390. This is the car that Steve McQueen drive it in Bullit movie
0-60 mph : 6.2 Sec
1/4 mile : 14.8 sec
Top Speed : 130 mph
