The last 289 I remember was in a 65 fastback Mustan, with a 4 speed, in 76.. It would clear a soda can on launch. Tested in front of our high school, on a concrete section of road. It had some cherry bomb type mufflers and was surprisingly quiet. One day headed home, tim lost a muffler in the hs parking lot and after the 5 mile ride home, I had hearing loss! Car was built in a gas station garage. Another quality build. Thanks for kicking in the memory machine.
I remember scraping a five bolt 289 because I wanted to use the more modern six bolt....I sure wasn't thinking about a restorer wanting one nearly 50 years later...
The aluminum Shelby CSX Cobra that the engine is going into is on the high seas on its way to the US. Thankfully escaped Somali pirates and Houthi rockets but it has further delayed the trip. Hopefully the engine install will finally occur this year and I will report back on the finished car.
What a nice little motor. Maybe I'm overly conservative, but I can't help wondering if given the modest nature of the cylinder heads that lifting the valves that high is of much real benefit vs increased valvetrain stress.
I have a 63 Galaxie 289 4 speed 5 bolt. Wondering if I can build this to push this heavy car or put my 428 in it. It runs great with 411 gears but like the sound and power of my 72 f250 390. 5 bolt 289 makes it tuff to add a 5 speed. to help it a bit. My 428 is at machine shop so will put that together for fun. Not sure what I will do with it. I have a lot of C6s here just colecting FEs and C6 for a while.. Im in the PNW so not many FE guys around here
Watched quite a few of your videos. I'd trust you. (Retired 45+ year engine builder). Question for you, young man..... Everybody's heard of the 271 h.p. 289 with the funky oil pan - but - I had a '65 Fairlane Sport Coupe, bought it when it was only a few years old from original owner - build sheet and air cleaner said 306 h.p. (4 spd car, braced towers, 9 inch @ 3.91 - was a special car, nothing in the car that wasn't on the build sheet and I miss it sometimes when I want to make someone wet their pants ......... and I've never seen another. Where does your Shelby engine fit between them, and how many stages of tune were there for the 289, fer cat'sake?
I’m a Ford guy, don’t get me wrong, but the only reason to build a 289 is for nostalgia and period correctness. 5.0 sbf roller blocks are plentiful. I would rather have the extra cubes and a hydraulic roller cam ready mill. A cheapo explorer motor with gt40 or gt40p heads would likely kick a 289s ass
As a former replica owner I think it is reduclious to spend lot of time amd money on a numbers matching engine for a car that is just a replica. If you want to be a 500HP 289 sb I am all in for any replica but numbers matching is nonsense.
The “replica” in this case is an aluminum body CSX, period correct throughout. Correct leaf spring and round tube chassis. Legitimate and accurate Shelby CSX. The process of making the engine to the same standard was not that much more expensive and a lot of fun for both Brent and me. I would agree why bother perhaps with the usual fiberglass replica with myriad inconsistencies with an original. But, with a highly accurate aluminum CSX it was an opportunity to do something special and enjoy the process. Each to his own.
@@naurybirnbaum7471 Brent builds a sweet engine! He is a mechanical engineer and knows his stuff. I applaud your intent for originality! I am taking a similar path. Yet, since you are building a period correct replica, there are a couple of faux pas in your engine build. First, the Cobras had 289 hipo engines in them. The hipo block had thicker main caps and the heads had cast-in valve spring supports. Nobody will know that yours is not legit, since you cannot see any of that unless you take off the valve covers and oil pan. However, the vacuum-advance distributor is a dead give away that it is a plain-jane 4bbl 289 Fairlane/Mustang motor. The hipos had dual point distributors. It is easy to swap one in, to keep your secret, but they aren't cheap! It sounds fantastic! on the dyno! Nice work, both of you!
I meant to include the harmonic balancer, as well, since it is also a dead give away that it is not a true Cobra engine... but it won't let me edit the post. Also, it is a simple swap - if it can be balanced to go with the motor.

Well I’m your first subscriber, and an early Ford guy looking forward to seeing the Little Snake!
I’m betting that super lightweight Cobra is very quick and great handling and balance wise that 289 under the hood. Great video Brent.
That is a beautiful engine. Great power from a stock appearing engine. Great work as always.
Beautiful job! Customer should be very happy.
That engine sounds very good.
Well done👍🏼
Cool build. Should be a little monster in a 2000 lb cobra
Great videos 📹 keep them coming
Content is so detailed. Love it.
Nice video.
I guess you have got to be part historian to do one like this.
Its a beauty Brent. I assume you used stock valve sizes? J Crane did a nice job on the head and intake porting.
Very impressive #'s from an early 289 with factory carb, heads and intake manifold!!
And sounds nasty AF! Nothing sounds like a healthy SBF....
Some clear valve covers would be cool; shame to cover up those beautiful rockers.
Nice. 👍
Great content as always. what was the compression ratio?
What a nice little motor. Maybe I'm overly conservative, but I can't help wondering if given the modest nature of the cylinder heads that lifting the valves that high is of much real benefit vs increased valvetrain stress.
There is no increased stress. That's an average valve lift for a street head.
I wouldn't have thought lifting the valves much over .5" or so would show much gain in those heads. I guess I'm behind the times.😁@@lykinsmotorsports
They will pick up flow to .750-.800" lift.
very nice,thanks.i just subed!
Got a 302 bored 30 and e steet heads larger valves used close Shelby cam elbroc intake hve id what hp tork it in my 67 gt clone 4sp
Id love a gt40 sound for my small block, any cam recs? Etc?
Very smart 🤓!!!

That 428 will give you gobs of initial torque to get you moving, even in a heavy car.
Very Cool, have a 64 390 I would like to do the same , hope you do the live chat
Did the hipo 289 have thicker mains than stock 289's
Are there stroker kits available for these 63 289s? Wouldn't that be cheaper than using the stock stroke crank?

Have you done any 347 cu in fords ?
Would love to see the motor in the car. Picture.! Is that a K motor or different.
That's not a K motor. It's missing several K code pieces, ie: harmonic balancer, distributor, and proper heads among other things.
Did the hipo 289 have thicker mains than lopo 289's
Yes, thicker main caps on the crank.
