Default Smoked A 428 AC Cobra Yesterday!

Had a great day yesterday. First we won 1st Place in our class at a car show (3rd Annual PA State Police Camp Cadet Car Show) and then on the way home from the show, we smoked an AC Cobra that was also at the show. The car had a 428 Cobra Jet motor and sidepipes. It was probably a replica, but that lightweight body and big-block motor were for real!

Anyway, we left the car show and were on a four-lane, divided highway (Rt. 309 northbound on the outskirts of McAdoo, PA). The guy did a flyby past me and then slowed down in the right-hand lane. I caught up to him and pulled along side. We were traveling at around 75 mph. The driver of the AC Cobra looked over at me, nodded, and stomped on it. He got about a car length's jump before I got into the throttle, but almost as soon as I did, the race was over. I pulled on him easily and had four or five car-lengths on him in just a few seconds.

He shut it down and gave me a thumbs up.

I'll tell you. Beating that car was for me way cooler than the car show trophy we won. When I was in high school in the '60s, the AC Cobra was one of the ultimate terrors of the highway. To whip one today some 40 years later was pretty cool.

Apparently they aren't much of a threat stock, considering that I took one by 2 cars when I was 100% stock. They are nice and they sound mean as hell though. Now, I don't know if it was an AC Cobra or whatever but it was like a 67-70 model with the 428 Cobra Jet motor in it. In fact, the car looks almost exactly like this one:

Well, let's just say I let more speeders go than any other violation.

That's it! They were no slouch especially in their day when a really fast musclecar ran in the 13s. Car Craft Magazine tested one in 1966 and it went 12.20 @ 118 mph. That's fast now. It was incredible in 1966!

No offense but the 427sc AC Cobra was the one in the 12's. The 428 version was about a second slower I believe.

The 427sc could do 0-100 and back to 0 in under 14 seconds. There was a remade one that Shelby did which did 0-100-0 in 10 or 11 seconds.

Awesome cars.

The original 427 Cobra was the fastest accelerated car in the world in its day.

No offense taken, however, the Car Craft test I read and have the information for was not the SC version, but the regular 1966 427 AC Cobra. The only thing they did was add a set of drag slicks to the car. Also, there's no way that the 35 less bhp of the 428 compared to the 427 (390 vs. 425) would have cost it a full second in the 1/4 mile.

Be that as it may, all versions of the AC Cobra were fast. Whether making 480, 425, or 390 bhp, that's a lot of muscle in a car weighing only 1800 lbs!

I know it was cool as hell smoking one.

Indeed, some fast cars even by today's standards.

Congrats on your win.

Hmm...sounds like an 1800lb kit car with a hopped up 302 in it. Very surpised you pulled him...if the numbers in your sig are still the same.

That idea "might" make sense if the car hadn't been on display for close to six hours at the car show. I think most of us can tell the difference between a 302 and a 428 cid big-block even without the air cleaner stickers.

The numbers are current, but they don't tell the whole story. My car is a real top-end monster and starting at a 75 mph roll put me right into its sweet spot. Besides all that, the '66 427 AC Cobra (which made 35 more hp than the 428) ran a 12.2 1/4 mile. I run consistent 12.0x runs so I don't see anything surprising about pulling on him.

I understand why your not surprised...you dont seem to understand how a roll race works. Your 114mph trap speed shows that your car is hardly a top end monster...no offense. Forget the 12.2 versus 12.0 numbers, its the 118mph versus the 114mph that counts when you race from a roll. Good kill, anything can happen on the street, but even when my LT1 had 368rwhp/336rwtq (3500lb raceweight) I pulled mid 114's mph in the 1/4 and thats leaving at idle every time An 1800lb car even with 320rwhp should be in the 116-118mph easy. Thats why I am surprised you pulled it "from a roll". Cobra kit cars with hopped up 302's run 12's all day (those cars have 260-300rwhp). Not trying to flame you...but the reasons I mentioned above are why I was surprised.

Well first off congrats that thing must haul some serious ***, but along with your car being a rocket cobras are more like 2400lbs with a small block and much more with an iorn headed big block. youre lucky he was stock, i helped put some headers on a friends stroked windsor and 400+rwhp in a 2400lb car is just violent, makes a viper look like a miata.

The reason I stated what I did is because at the drag strip I make most of my gains on the top-end as indicated by my timeslips. To me, the car feels its strongest at the end of the 1/4 and still wants to pull hard. Also, I don't understand how you can so lightly dismiss a .2-second advantage in the 1/4 mile. Your ET demonstrates your car's ability to accelerate, i.e., win races. The trap speed is an indicator of power output.

In any case, thanks for the insight on the Cobras.

ilovefirstgens: I never weighed an AC Cobra so I really have no idea what they weigh for sure. I got the 1800 lb. figure from an AC Cobra web site fact sheet, but it could very well have been wrong.

The only things I really know for sure are:

1. The car was an AC Cobra (undoubtedly a replica).
2. It had a 428 big-block motor and sidepipes.
3. It sounded WICKED, I mean really BAD-***!
4. The driver of it seriously raced me. There's no doubt in my mind he had his foot all the way into the throttle when he took off!
5. I beat him fair and square and that's all that really matters to me.

Good Kill. I got a chance to ride in a 427SC and it was a monster. I really want one just for shows and sundays crusing. Good Kill
