While I know most A bodies have the aerodynamics of bricks, I'm curious to see the highest top speeds you guys have managed to wind them out to on "closed courses".My Scamp wont be running until I finish a couple projects that are ahead of it so I'm out.The fastest I've gone was 115 MPH according the the GPS but that was in a 84 nissan 300ZX turbo that was aerodynamically challenged(bought it after a carport collapsed on top of it after 3 feet of snow,so the back is exposed to the elements so it generates alot of drag).

I pinned the speedo in my 69 340 swinger a few times back in the day. My 79 5.0 Mustang I got up to 5400 rpm in 4th gear which was an over drive. In that car it was 2100 rpm at 70 mph. So do the math and it should have been 140 plus????
 
67 Barracuda 130mph. I just posted a thread on here asking how I can get more top end speed.
 
When I first got my Dart and after I made sure the wheels weren't going to fall off, I opened it up on a long straight highway. Speedo was pegged both ways, down and back. I would imagine with the right engine and gearing anything your budget will allow is possible.
 
'76 Scamp, 360 with cam and bolt ons, A833OD in 4th, 2.76 gear, 26" tires, 4200rpm on the tack, Says it's 140give or take. The car had stock everything and needed all three traffic lanes to get around bends.. But it did it. I've had A, E, and C body cars past 130, a couple past 150. Someday I'll have to get one to an actual race track...lol.
 
My 67 Dart, on a 1.8 mile road course at No Problem Raceway, Louisianan, with a 360, 4 spd, 26 inch tire and 3.55 gears, 121 mph. They use the 1/4 mile drag strip as the main straightaway. Gears where the only thing slowing it down, that and pushing a barn door through the air.
 
I've had my 66 up over 100. My old Road runner over 120. A 2010 SRT8 challenger well over 120. Tony accelerated it up to 145 in 5th and still had 6th to go. It's the old cars back in the day with 4 wheel drum brakes and bias ply tires that are scary.
 
Wished I had GPS technology back in late 80's, but all I can go off of is numbers.....
My 66 Cuda with a hot 273, 904, 7 1/4 rear with 2.76 gears and 235/60/14 tires running full throttle down a long open road at 7k RPM. Had friends that used to top end challenge the 66 all the time as teenagers when we got closer to home town so if anything broke we didn't have far to go.

Sounds a lot like a set-up I had. According to the Montana State Police, you were doing about 110. LOL
 
OK, now who has the fastest car, after you calibrated the speedo?
 
Brand new cuda in 1968, 383 4-sp, 3.55= 90mph in 3rd gear. Ran out of room, backed off.
 
i know a guy who was clocked at 143 mph by provincial police radar in his 69 340 GTS back in the day.
Don't ask me how i know.
 
I can take my dart to 120 or so. It has a stock 318 2bbl, an a-500, and 3.23 gears.
 
My Duster on 1/4 mile track traps at 115 mph at 6000 rpm. 408 w auto & 3.55 rear, 26.5" tire. Still pulling hard.
 
I have a factory a body speedometer that maxes at 200. I got all y'all beat because my car will push the needle around to 160-170 easy.
 
With my original 65 Barracuda 4 spd set up like a Formuls S, I got a long straight downhill run. With the Speedo saying 130, the Cuda lifted off the highway. The aerodynamics are that of an airplane wing.

Wife’s ‘67, 130mph with a good bit of rpm to go.

Logan, with only so much aerodynamically we can do, so, the rest is HP and rpm. PM me.
 
I couldn't tell you.

The old '72 Duster had 3.23's and I'd shift out of second into third at around 6200-6300 r's. By that time you needed to look down the road a 1/4 mile ahead because what was coming was coming in a hurry. Looking down at the needle was a luxury you didn't have.

Funny aside, for all the high powered cars I've driven, the only one that made my stomach flip was the old Hyundai XG350. Full throttle it would slide into 5th gear at around 100mph. The engine would go lean, the r's drop off, and then rebound in hurry. Instant stomach flip.

I never had enough road to see how fast that car was. I had to pull a maneuver one time where the throttle was the way out. By the time I had the ability to take my eyes off the road and was out of dodge, and lifting off the throttle the needle was coming down past 125.
 
135 mph at Willow Springs. The gauge is really funny in a '68 Dart. It slowly climbs to 95 mph then drops to 120 mph where the needle maxes out. Lol.

That’s crazy.

106 was my best trap on the 1/8 with the Fish. That was enough with the skinnies up front. Got that kinda speed in the SuperBee and it was floating to much. Those days are gone!
