What goes around comes around for that dude that screwed you up. Try to forget about it or it will eat you alive. I have seen people get ate up with hate in my life and it kills people, very slowly. Peace. That 401 sounds like an American V8 for sure.
I’m STOKED everything finally worked out for you after what was obviously a big disappointment.
Thanks for explaining about those plugs and the issue they caused…. Ooofff 😳
A 425 c.i.d. 1964 Wildcat two-door hardtop was one of the best cars I’ve ever owned.
Good Day. Very Nice. Long sad story & $$$$, BUT, Wonderful final result. Thank You.
200+hp SAE at the wheels is pretty good when you factor in turning the ST400, 9 3/8” rear and all the accessories for the conversion from gross hp. Hard to find good machine shops nowadays that build non Chevy small blocks.
So glad I found this channel. Great content. I just found a 401 for my 53 Studebaker Commander! God bless!
Awesome! Thank you!
O love that,!!!
I like the shiny green you chose rather than the duller satin and flat green colors. The shine give the motor a bit of a sparkle of reflected light I like to see in the engine bay.
Great story! Can relate to the frustration you experienced. Had my 425 machined by a shop who specialized in small block ford n chevy mainly. They called it a boat anchor and once i had it running it had all kinds of more sludge in the coolant passages from their hot tank job. Remedied that by running tide detergent through the cooling system. Long story short this engine still runs today as this happened in the.late 80s to me.. Thanks for an indepth inspiring heads up video for those of us with oddball engines.
Congrats on getting it running! I have a 63 Lasbre 2 door sedan, and live in Montgomery. It's good to see somebody other than me with an x frame buick in this area! Thanks for sharing.
Bro, one thing I have learned about building engines is that you have plenty of knowledge to do it yourself. If there are any tips or tricks, we have the Internet now, so all that is available to you. I feel for you. Only one time did I have a shop rebuild an engine in my life. They knew how important an engine it was too. They screwed up everything, and they build NASCAR engines. Seems they were funding their NASCAR by giving the shaft to all the customers. Never had any problems with engines I built myself. Yeah, sometimes it took a long time, but I was younger then and it did not matter, it was done right.
She’s a head turner !
D .Im glad it worked out for you and sorry for the way you were treated by the original builder.
I remember reading an old magazine article from the 1960s where a 67 GTO made 200 rwhp after tuning so 200 from yours is strong. BTW, one of our family cars was a 66 4 door hardtop Wildcat with a 401 4bbl. I loved that car, and the 64 2 door Catalina before it.
I am very glad that you have the engine fixt Rolf from Sweden
I love the engine rumble and exhaust sound of that big wildcat! The big low to mid range torque on power of that old traditional American V8. Not the wheeze and blatty discordant noise of the newer so called low restriction 6000 rpm v8 noise makers so popular today.
Nice nail always more torque. Style
That sucks the guy sank it too much.glad she is finally running.I’m still putting mine back together .I have a 63 Buick Electra sports couple.the motor was seized.I got a 401 out of a 64 wildcat that had 29,000 original miles .I took it apart to rebuild it anyway
I love buicks
Great video I just inherited my late father’s 63 Rivera with 401. He bought it brand new to take on his and my moms honeymoon so a one owner
That's a great story!
Hard work and dedication
Oh the 401 "400 special" is a epic one 🤤
Hello my friend! I'm happy for you! I was waiting for this video of your victory! God blesses! Keep up the Buick videos! Strong hug!
Hi, I’m Donald Adams, I’m a NailHead Freak and since that’s a WildCat, I was wondering if you were aware of the Automatic Transmission Additional Power Add’r ? If you have a 300ST Super Turbine 2spd, it has a 2,800 RPM Stall Convertor w/Switch Pitch that’s activated by an electric switch mounted on Carburetor Linkage. You drive around in 1,800 RPM normal stall but 1/2 to Full Throttle, the transmission switches to 2,800 Stall Speed which is like installing 4:11 rear gears. If you have the 400 3spd transmission, that has a 3,400 Stall Speed which operates the same way as 300 ST but is more like installing 4:56 gears in the rearend. These cars Love Full Throttle/Full Power Braking Launches and keep going up to 135/140 mph “ Quickly”. Try it out & let me know how much MORE exciting racing is !!! 😎😇😎
Awesome! I'd love to see this car!
Nice work!! Glad you finally have this sorted out.
A true forever car❤
i'm 62. when i was a teenager i bought a 1966 buick wildcat 4 dr. with only 19,000 miles and a beautiful 401 nailhead. i remember spending hours admiring the appearance of that V-8. the thing is, i distinctly remember it having almost aqueduct like exhaust manifolds, each side having two arches. yet i don't see that on any of the 401's on youtube, even '66 wildcats. can someone help me out with this?
i think i have a photo of the engine that i took around 1982 but i haven't yet been able to find it. if i do i will post it.
Sounds GREAT
you da man!!

There must be a very big difference between those original SAE gross ponies at the crank with no accessories installed and the SAE net ponies at the rear tire ground contact patch. Looks like your losing close to 30% of those ponies on the way to the dinner for that hamburger. That’s seems to be a lot of power loss in the driveline.
This is a shot in the dark, but I’m looking for a self adjuster actuating link for the front drums on a 1967 Buick Electra. It’s the skinny rod that goes from the actuating pivot, to the anchor at the top. Do you possibly know where to order this part? All I can find are springs. I’m also trying to find a drum as well. Thank you in advance.
There is a backing plate on eBay right now that includes the rod. You can find it by searching "LH FRONT DRUM BRAKE BACKING PLATE 1965-1970 BUICK." I also recommend a drum from eBay, then take it to your local brake shop for machining.
Those 401 nailhead engines are strong! I have a 65 Wildcat 401 runs like a champ. I had the warerpump and hoses recently done but I noticed a few weeks after this work that antifreeze settles on top of the intake manifold after I let her run what could side this? Nice video!
Are we talking about antifreeze settling on top of the intake manifold where the carburetor sits, or antifreeze settling on the "top" of the engine in the valley under the intake manifold?
Hello ,Good day , my name is Fatih ,l am writing from antalya ,turkey.l have a 1967 pontiac parisienne
I do screw in plugs on everything but they make short ones or you machine them down. Sorry you had this happen.
My car is 6 cylinder ,l have been trying to make it 8 cylinder for a long time and found an affordable engine , this engine is buick 322 nailhead
Where did you get that aluminum drum from? I'm about to overhaul my wife's 61 Buick's brakes and I highly suspect the front drums will require replacement.

@@1964buick thanks!!
I have a 63 Buick LeSable 4 door hardtop with the original engine that needs rebuilt. Could you recommend an overdrive transmission? Thanks
With a 1963 and the Dynoflow, that's out of my wheelhouse. I'd recommend talking to the guys at Centerville Auto Repair, Russ or Matt. They are experts and sell all the adapters out there. I know I've read of 700R4s and 4L60E/4L80Es being adapted, but not only is there the adaption that has to take place, there are firewall and floor pan clearance issues that need to be accounted for.
What is the name of the guy who swindled you.
David Gaines AKA "Dual Quadism, dualquaddave" on social media. Southern Florida. Ft. Lauderdale/Hollywood area.
What's your timing at I'm having a hard time finding what my timing should be set at
I had my distributor recurved so my car is not a good example.
A Nailhead expert, Tom Telesco, recommends: 8*-12* initial. 30*-34* total all in by 2400-2800 RPM's. Complete total incl. vacuum 42*-46*. Listen for any pinging & back off as nec.
@1964buick sweet I'll double check that when I get home. Also around 1500-2000 RPMS when cruising she acts like she's got a misfire, no vac leaks, new plugs and wires I'm lost
I would like to have that engine in a 40- 50's Chevy truck.
GM used the Nailhead in many of the old school busses
What's the name of the business that relines the brake drums?

Can I borrow your motor for my 61 Buick Invicta Convertible? Jk Learned a lot from your videos. Thank
Gald everything worked out. They say, dogs look alot like there owners... just saying.
Real cars before the pests at OPEC and the epa got teeth.
You ain't kidding..
I'm wondering what carburetor you are using. What is the cfm?
I'm using the factory carburetor the car came with, a Carter AFB. Because it is factory, the CFM is not listed on any factory documentation. Here is part two of where it was rebuilt: ruclips.net/video/LlmOsMHRY1Q/видео.html
Don"t quote me on this, but I think the flow for the AFB was ~600 for the Buicks. The dual-quad came with 2 ~450s@@1964buick
I hope there was a lawsuit.
Can I get the contact number for the rebuilder…
LOL
@@1964buick LOL thank you
I'm 60 years old then boldly onto Buicks in my life 69 in the 72 and the engines were red
Absolutely. Depending on the year and the make of the Buick motor, they have been bluish, green, silver, and red.
The Straight 8 and up here on this end ... I've owned a bunch of Buicks in my lifetime
