1966 K code Mustang Fastback - unique for a number of reasons!

In this video we walk you through the unique specifics on this K code Mustang that make it rare even among other "NON-Shelby" k codes. We also go on a test drive where you feel the power of this solid lifter HiPo 289 and hear the exhaust roar!

In one of my K code fast backs, I replaced the 289 with a 302 hi po. Made a real improvement in power and personality.

[@TheGunfighter45acp]

That paint is gorgeous!

[@QualityClassics]

Yes she is!

[@johnadams9044]

Very nice collection of Mustangs.

[@lucafranco8872]

A dream for every 🐎 lover!! 🔥❤️🤠 The sound of the engine is pure heal for the soul

[@jerrynavarro2404]

The 65 ford mustang fastback K code mustang are king of the crop in my mind !

[@stevegarrett4869]

agree on the manual steering, you get a better feel through the wheel.

[@QualityClassics]

I should have stated that K-codes did not come with power steering, not most of them did not .... none of them did.

[@QualityClassics]

A comment concerning the "PRODUCTION NUMBERS" shown at the end of the video. The methodology used in coming up with the estimated production numbers in the video was statistical extrapolation based on a large known sample size (i.e. HiPo Registry). The sample size does NOT include the 1966 Shelby Hertz cars, rather it is Non-Shelby K-codes only. One more clarification - K-codes did not come with power steering.

[@dinorossi6611]

I love it. Clean n powerful

[@QualityClassics]

so ture

[@colinsdad1]

I'm in the process of building a newer "homage" to this car- a SUPER rare, #10 of 100 built, 1995 Steeda Mustang with a .030 over 302 (306 CID), built by Blueprint Engines. It's got an honest-to-God Holley 4150 4-bbl on it, with a built World Class T-5 in it. The obviously green engine dynoed 420hp@7500 RPM with 390 lb.ft @3400 RPM. With the Steeda suspension upgrades, this car will truly be a newer K code!! Awesome video- too bad it wasn't a 4 speed....

[@QualityClassics]

cool

[@jimmorgan8748]

I had a K code when I was a kid that I should have kept. It was black with a 4 speed.

[@johnlambert6205]

Amazing !

[@QualityClassics]

thank you John

[@RtB68]

..."She's going to go faster than I want to go"... Lol. For God's sake man....the people NEEDED to hear it move into 3rd... I'm giving you a fail just for that - and I love your stuff.

[@QualityClassics]

Hahaha 😂

[@jimwhite9605]

Good job

[@QualityClassics]

Thanks!

[@johnadams9044]

There are not special heads in the K code engine. It is the same as the A and C code engines.Same heavy low rise iron manifold as well. The K code engine does however have the high performance cast iron exhaust headers.

[@clarkgriswold5903]

I bought a new 1986 GT silver auto back in the day, what a blast I had!

[@cooperparts]

I had a 85 gt installed 125 NOS ran 1291 at 105 at maple grove ford weekend 86

[@cooperparts]

Stock 86 would beat my 85 by one car coming out of the hole never could never get it back 1490 stock injection ran 1470s

[@thivicc2683]

Epic job and an absolutely AMAZING car!!! LOVE IT!!! Also, whats the name of the intro music? Please and thank you

[@QualityClassics]

thank you, I will have to ask my son about the music

[@thivicc2683]

@@QualityClassics Thank you wo much, it is much appreciated! Keep up the great work, i love it! I wish all the best to you and your family!

[@geoffreydemaesschalck6065]

Gorgeous car ! I love a K-code, but with the amount of miles I do, I prefer a more tame V8 with less maintenance, gas consumption and less budget in case you need to make repairs. But it looks amazing and sounds great !!

[@QualityClassics]

Yep, the K-code was more of a special purpose car, although I take road trips in mine given the benefit of the 5-speed (serious game changer) Thank you.

[@bluidog2]

My brother had one. 1966 4 speed. Metallic blue. I did a brake job on it 4 wheel disc.

[@QualityClassics]

sweet

[@scotchbudmeister9018]

Beautiful! Do you know the axle code? At 4:10 it sounded a little wound up at highway speed - but in a good way. Thanks again!

[@QualityClassics]

Rear gear is a 3.50

[@clarkgriswold5903]

You need to show us how those fastback vents work!

[@QualityClassics]

good idea, will do that on an upcoming video

[@richardbarkley9909]

I HAVE a '65 K GT Convertible, I rarely see the decals on the valve covers like your '66...…..Are they somehow correct for a '66? Also, My restorer originally put the sticker on the oil filler cap then said it was incorrect so he removed it.....And there always seems to be some controversy as to the placement of the Autolite spark plug sticker on the air cleaner lid-some say it should face the passengers side, some say it should be directly opposite the main "289 HiPo" sticker-I put mine on magnetic paper so I could move it anytime I wanted.....

[@QualityClassics]

I need to do more research myself before responding.

[@edcain3676]

THE Most Correct,RARE & SHOW READY K Code GT FB I've Ever Had the Pleasure of Observing.Lots of Collectors Would Have Objections to the C4,But Believe Ur Son Mentioned Its Probably SAME Upgraded C4 Offered in Trucks & I Can Tell U From My Experience W/My Former 66 Merc.Cyclone ,It's A TOUGH Auto Trans.

[@QualityClassics]

Thanks Ed!

[@valentino1215]

I think your numbers are a little off. 692 automatic k codes? Are you factoring in the hertz cars that were also k codes and the 950 that were automatics as the first 50 or so were 4 speeds? Also factoring in 3 production plants?

[@QualityClassics]

Correct, I failed to mention that these are non-Shelby numbers, good catch (yes all three plants included)

[@valentino1215]

MyRod.com you’re still basing it on a registry where people volunteer their information. Without the actual production numbers we will never actually know. I get what you are trying to do but others are going to assume these numbers are correct and spread those numbers around. Just like everyone copies other people’s markings and don’t actually do the research and see what came on their own car. I am a gold card judge for MCA.

[@QualityClassics]

@@valentino1215 Statistical extrapolation based on a large known sample size (i.e. HiPo Registry) is the most “accurate guess” known to man. I point out the method of quantification. You are correct, no one knows the exact number but there is no harm in making an estimate based on a methodology that has mathematically been proven to be the next best thing to knowing all there is to be known. I failed to point out that Non-Shelbys were excluded in the sample - if anything this is the accidental misleading part. In any event, thank you for your comment.

[@QualityClassics]

@@valentino1215 "Statistical calculations when based on a large sample size" are not 100% precise, rather very good approximates and a great benchmark when hard numbers do not exist. Statistically speaking the numbers are correct.

[@steveandrews282]

Doesn't anyone brush paint the pinch welds black like the factory originally did?

[@danatara69]

all that power with drum brakes ? scary

[@QualityClassics]

Disc on front, but still not enough for all the power

[@vincesharpguy9942]

I was under the impression that California special k code was the Unicorn

[@QualityClassics]

it would be except there is no such thing...NO k-codes after 67 and the SC was only 1968

[@jonlennon3348]

I seriously doubt a stock 271 hp engine with cast flat tops would do at 8000 rpm's seeing as it doesn't have enough valve spring to avoid float.

[@QualityClassics]

Ford built it to potentially go that high, but you are correct it likely would never achieve it without modifications. 👍🏻

[@cooperparts]

I think they could very small valves I think red line was 7200 the exs valves chrome plated

[@WilliamSmith-nm6wt]

The k-code is 'Solid Lifter' engine.

[@QualityClassics]

that is correct

[@jesse.minton]

what's the top speed on that?

[@QualityClassics]

good question, too chicken to find out

[@briansredd]

The K Code C4 was unique somehow?

[@QualityClassics]

The C4 in the K-code is different, it is a "beefier built" C4 than other Mustangs had - they have a "C" on them denoting that they are "special" transmissions and are not found in any other Mustang.

[@mrdiplomat9018]

MyRod Classic Cars - on your test drive, you said C-4, but later you said it was a C-6, but c6s were in the big blocks only, yes⁉️

[@cooperparts]

I had one in 75 before I could drive (78) k code 4 speed no ps steering paid a couple hundred dollars a title never drove it on the road dad said it needed lifters because they tapped

[@QualityClassics]

wow

[@johnnysamples]

Thought the glovebox door was wood grain

[@QualityClassics]

this is a factory K-code but not a factory Pony interior car, thus no fake wood grain glove box

[@Ndiver81]

If the Marti report’s didn’t start until 1967, how do I know this is the real deal? What documentation is available for this car? I would want to be very sure that I’m getting what I pay for. No disrespect intended nor inference implied.

[@QualityClassics]

I would start by purchasing Tom Gregory's book, "The High Performance Mustang" (4th edition). Original vin#s stamped into the car, engine and original door trim tag with matching title along with original components on this one. Also, hire a K-code knowledgeable inspector .... hope this helps

[@Ndiver81]

MyRod.com Great. Thanks for the info.

thank you

Silver frost is sex on wheels #66 K code weapon.

[@QualityClassics]

Yeah, it's a stunning color.

[@FaithfulServant316]

Nice K code, Too bad it's not a 4 speed. You can buy a 2020 Shelby GT350R for ALOT less money and alot more fun.

[@QualityClassics]

true for some but not all

[@roymontero4066]

"kay coad"

[@LarsLawson]

In 66, the dainty snowflakes convinced Ford to make an automatic transmission available for the hi po engine. Whooptee do.

[@johnadams9044]

Hee, hee ha. Might 271 H.P. Today's muscle cars develop 300 H.P at idle.
