Lou was always ahead of the other hosts. Need him back!
Always loved Lou! He has so much energy and always a positive attitude!
I guess that makes up for his lack of knowledge.
The world just wasn't ready for Lou back then. To bad. He's turned into one of the best hosts out there today.
He just hadn't met his soulmate Jared yet. Those two just click.
Yea if you say so! Disgusting they are apparently ready for jokes like this now!
@@unicornsteaks6769
What you be talking bout Willis ?
No really I'm trying to put 2 and 2 together from your comment ....Jared the boy toucher from Subway??
@@MrTheHillfolk yea him or the other host of car fix.
john k never liked him. Still don’t.
Its nice to see a Pontiac V8 being used. I have a 1972 455H.O, out in my shop. It's built nicely, and it will scream.
I had one in my '71 T/A with a Muncie 4 speed. I loved that car.
@@shawnrenaud2252 What happened to it??
I love those years of Lemans and GTOs! I graduated from high school in 71 and 2 seniors had them. One had a Lemans and the other a GTO. They were 66 and 67. Both the same color, dark cherry red, with black vinyl tops and cragar mags.
Great to see a. Pontiac in m Pontiac
Wow, great job Lou,from an old poncho guy. You answered every question that I wondered about. You gave some "pontiac points" that perhaps some folks arent aware of regarding their motors. Maybe gave some hope for some of these 326's lying around. Impressive numbers for $5 grand.
Lou is a awsome person. I met him at the PRI "Performance Racing Industry show" in Orlando about 10 years ago. What you see on TV is what you get in person. Lou if interested in more Pontiac's I have a 1967 Firebird that the engine needs to be redone. In closing, Lou thanks for your service.
Lou is the best! I met him in CA. He’s a class act. 👍🏻
Love the car. Personally I’d have given the 326 the heave-ho and gotten a 400 or 455. All 3 are externally the same size.
Yeah, but then Butler wouldn't have been able to pay them to showcase their stroker assemblies.
As a people mover the 326 was a great engine, the made satisfying torque with their long strokes, the tiny bores aren't great for power though. Even the 455 bore is just a hair bigger than the bore of 400 SBC.
Same here brother
My stroker Pontiac was a 428 .030 over with a 455 crank. 444 cubic inches of tire shredding torque.
Great work Lou, and thanks for the professional mopping tip. That's how I'm going to do it now.
My Mom had a 65 Tempest when I was 9 or so, It is one of only a few cars that I rember from childhood. And I grew-up in a Really memorable time for Cars...
PONTIAC FOR LIFE!
I rebuilt my gifted 65' LeManns when I was 15. I cant remember all of it, that was 40 years ago. I remember all of the Pontiac engines using the same block. I got some junk yard heads from a Catalina, a 455 intake and an Isky cam. This was in the 80's. It smoked the GTO's in my neighborhood.
2 speed, slip-n slide!!
Unique and fun engine build. 👍
Really nice. My favorite though was the 1964 LeMans.
1962 Pontiac 421SD had over 485hp and close to 500 pound ft of Tq. There is a you tube video of a Butler built 421 Vs 409, check it out
Glad to see Lou take the lead for a change, excellent job by the way! Always liked those ( W ) block 409's. In case you didn't know, you can buy a new "w" block through the after market and it's very much improved over the factory ones. Enjoyed the 326 stroker to 375ci build, great show you guys !!!
LOL. "bring back his tools and make up with him".
Lou u r amazing man! Your funny humors make me laugh a lot.
I'm looking forward to see u more.Good luck.
God bless all of us.
You do know how old these episodes are right?
Funny this showed up, I happen to have one of these cars in my yard wit a 326, Now I'm really thinking stroker :)
Do it brother.
Very glad this is being done instead of making it another rock crawler like someone else did.
Gotta love a Squid, certainly knows how to swab the deck. ;)
Edit: Love from a Dirty Leg
MAN WHAT A GREAT UA-camR❤
LOVE WHAT U DO!!!!!!
JUST AWESOME
KEEP UP THE GOOD WORK
Hell yeah shipmate. Great build.
Love It wish my old 67 Firebird had that braking system and running gear, Old Vet Tom
We really need to see more of this. Everyone is throwing in crate motors. That is rarely how it's done. You usually want mods and a salvage or the original motor is usually the choice.
Excellent work..!
I really like a good care of all parts of you and a very high quality service at all.
Cheers from Istanbul...
That engine is beautiful.
Damn this is a super trick setup 🏁
beautiful work
lou deserve his own show..
If you stroke, don't deck the block or the heads as parts may collide, then BOOM! Depends on how much stroke you intend to put into it. My 1966 GTO had a 428 H.O. that was prepped. All cast iron. 4 speed Super T10, 12 bolt 4:10:1 rear. Could wheel stand in any gear. Top end was 125 m.p.h. Basically a town car. Not for the super slab. Ran 100 octane AVGAS. Good to have airport connections. Sounded good@3000 rpm with unbaffled 3" side pipes. Best damn car I've ever owned. P.S. Not a fan of lowered cars or trucks except if they're strictly used on the track.
That was a very nice build.
Awesome build!
In the 60s i delivered pizza in Detroit, with one of these 326 w/3 on the tree. Really good car.
I'm a true Mopar guy but if I was to go with a GM product it's a Poncho all the way
I am 100 percent in agreement.
Or just Butler engines all the way..
Im a Pontiac guy who went Mopar
They aren't nearly as bullet proof as MOPAR or Chevy. If you don't address the stock oiling flaws they spin a bearing predictably ~6000, due to oil starvation, takes to long for the oil to drain back down to the pan. Plus you are always limited to a fairly small bore because they never made a big block, so the big displacement engines are effectively strokes from the factory.
Same here, Pontiac is basically GM's Mopar as well as America's BMW.
The brakes are for an A-Body, sweet build!
what a great host.
Been a fan for years but this and the Firebird were my absolute favorites. Closely followed by the 225 Leaning Tower of Power.
Can't wait until the finished car.
Lou is a great show host!
love the pochos, so great content, great show. now dont forget to fit the headers before you bolt the engine down
You're about 18 years too late with that advice...
Thomas Daddio thanks :)
A beauty!
Lou Rocks!
I love tht color on tht engine 👍👍
Butler baby!
I wish this show would come back 😭😭😭
It never went away...
All right, I like this guy I like the build on the car, if you ignore the transmission, clutch combination, and dual quads on the it's a somewhat realistic build.
but there's no way that they're going to turn a 360 flywheel horse engine into a 400 horsepower engine with some "in car tuning".
That's how it was with these Old-Timers. Put the motor in the car and just make up whatever numbers you want to for what it makes.
That’s episode takes me back hahha
That car is screeeeeeeeaming for a Gear vendors overdrive unit behind that super T-10 !
You know that lemans looks good when they pop the hood.
How can someone not like this?
How I miss Lou on Muscle Car, but at least he and Jared are on CarFix.
Not anymore. Newest season has Brian Fuller
What happened to Lou and Jared?
Good job, Lou. Surprised Butler didn't advise against that intake/carb choice for power. Looks good tho.
I have only one question. Why ? The Poncho 326 has a small bore, and a stroke that is already too long for a engine of 326 cubic inches. This is like a bad idea all way around. Build a 400, 428, or 455 where there is some serious power potential.
Because he can, they’re out there and why not? Still a good street rod engine.
Probably because they already built one of those.
I guess to be different but yeah either the 400 or the 455 would've been a much better choice.
It's just fun to do something different sometimes.
I think the point they are making is just to see how much power they can get from the original block. Expensive? Yes but they have the money because it's a TV show. It's also a plus keeping the original engine in it too.
This engine is well capable of making well over 400 HP.
So cool
You are awesome!
Lou and Tommy together on MC. I'd just about pay money to see that.
In 1982, I bought a 67 Pontiac LeMans with a two speed powerglide transmission and a 326 motor, most of my high school friends laughed at me and said I bought a grandpa's car, then I started repairing and rebuilding, rebuilt a transmission with the biggest strongest components I could find at the time, rebuilt the motor, had to block balanced and blueprinted, had a custom built cam with a long duration put into it and stroked it, I put roller rockers on it and studded the head, I also put studs in the block for the main bearing caps and for the exhaust manifolds, Iput a blower on it as well as nitrous. Had the rear end gone through and beefed up, had 3:73 gears put in it, and an eaton locker, had custom-made axles put in it and of course all new bearings and seals, put some traction bars on the leaf springs to eliminate the axle twist, some wider speed rated Mickey Thompson tires on the rear and heavier duty speed rated MT tires on the front,Without using the nitrous I could accelerate so fast that I could pin $100 bill on my dash and if anyone could lean forward through the g's and grab it they could have it, needless to say no one ever did.
Love from Munich Germany
I like that ice blue Pontiac painted thier engines
Yeah, like the darker silver blue over the 'corporate blue'...
Butler Performance truly is the best in the industry when it comes to Pontiac's.
you mean the Only one in the Industry for Pontiac's. :)
Nice engine work and I love the rear end, no pun intended, it is just what the build needs.
Had a 65 LeMans with the 2 speed power glide automatic. Best 2-Door car I ever owned, fast and handled very well on the straight or curves. Most thought it was a GTO, one guy even called it a Tempest. Traded it for an AMC Matador 9 passenger wagon with a 401 V8, when I got married with kids. Oh well you Do learn from mistakes of All kinds.
That gunk in the upper tray was just Nasty, did they Ever change the oil or just top off with the same filter, for how long? lol
The Pontiac never used the powerglide.
It used the transmission was the Super turbine 300. Look it up. It's even in the Chilton manual.
This episode is so old UA-cam had to stretch it from 4:3 to 16:9.
Ah Common Bradley' your just a prude~!
@@georgeveghte6459 I'm not sure what makes my comment prudish, but if you saw the contents of my hard drive I doubt you'd still call me that lol.
This is so old 357 HP from 376 CI was impressive.
16:57 It was made in 2007. So 13 years old.
At the Westech dyno facility, ten days before the first Engine Masters contest, MY 326 made 551 hp. Use us for REAL killer torque numbers. At 3200 rpm our street pump gas 455 can make 600 lbs ft of torque. Nice driver you bet
Long stroke engines like the 326 make excellent street engines.
You need to do A 455 GTO 4speed with tri power love your shows Awesome builds
I always enjoyed his commentary....wish he was still a host.
I prefer using black epoxy primer and then coat with polyurethane clear on my frames & suspensions parts. No sanding between coats and a super tough finish for cheap.
I worked for Pontiac. For the record the 326 was not 326 ci. It was a 343ci engine. DeLorean was told NOT TO EXCEED 326 cid. That was how it evolved.
This host isnt doing this anymore? Hes the best
Crazy to see Lou in Muscle Car... I keep expecting to see Jared walk in with a funny T shirt.
Jared used to be his co host on musclecar too. He left though and went back to Rad Rides by Troy...
"Even stock parts are fun to put on."
Nice work, gonna be a nice ride. Is it preferred to balance the flywheel w the new updated engine? I like the clutch system.
Always nice to hear someone who actually knows how to pronounce "Impala"; theres no "U" after the first "A"!
Dana Reynolds impaley lol
Probably cuz they watch those nature shows about the Impalas in Africa they act like they spell it differently
I hear ya. I been saying it the " right " way my whole life. Then I hear some dipstick say it like the don't even know what a Impala is.
Dana Reynolds This has gripped me for years so it is good to hear someone pronounce it right and someone else say it. I think the west coast pronunciation is Impala!
Midnight Trumptrain wrong it is Im pal a just like the the animal. That’s why the Impala is in the circle. Contrary to some negative people.👍😃
I guess if you want to keep it numbers matching you do this but I wouldn't spend 5k on a 326 when you could spend 5k on a 400-455. Back in the day we used to give 326s away and just replace with a fresh 400 !
Your not wrong, but for some as you say numbers matching and power. Also good 400, 421, 428, and 455s are getting hard to find and some people want an arm and leg for them.
@@EfurdGarage Yeah, but you can still find a junk car Catalina complete with a rebuildable 400-455 for dirt cheap. The ones that are expensive are the ones that the engine is pulled . They're still out there , you just have to look .
@@benkrom2737 not many where im at most have been picked clean or crushed. Most of the big cars that have not been picked yet thye want a pretty penny for still mostly becuase of the engine.
@@EfurdGarage LOL, you made me look, I found one asking $1900 complete and then a 67 grandprix all complete with good chrome 8lug wheels all there for $3300. All those parts including trim interior all there , car looks like it has every option you could get. Looks temping just to restore the car. Rare for the 67 is they had a Carter 4bbl Qjet not a Rochester. Ahhhhhh tempting !
@@benkrom2737 car like that you wouldn't want to tear apart lol, i didnt say it wasn't possible to find them i just said it wasn't as easy. But where i am at you just dont see many old pontiacs anyway, hard to find unless you wanna drive a ways. its kinda why i have been hording blocks
De Brazil, topppp
Cool they reworked the factory heads but since Pontiac used bore and stroke to change size, any aftermarket head would have worked and better money spent/ more performance.
top second responder
I've been waiting fo someone to build a 326 or 350 Pontiac, especially with dual quads or three deuces.
Why didn't you finish tuning it in on the Dyno? It be really nice to see what it did all Tuned in
Right?! Wtf lol?
There's so much potential hidden in the 326 bases 375 Stroker.
Lou knows his way around that mop... you can tell he was Navy.
the best thing to do with a 326 block, is pull the crank, main caps, etc and scrap the bare block, or paint it, and use it as an end table in the garage. it only has a tiny 3.72" bore, around the size of a 283 chevy. major cylinder valve shrouding issues. Pontiacs are heavy cars, without at least 450 ft. lbs. torque, they are a slug.
No lifter valley paint? Is it a waste to paint the valley? Thanks for the great videos!!
Glad to see someone mess with a small bore Pontiac, even if its an old episode. Besides the large ports, the other two benefits of the LS engine from GM is the long connecting rods (which Pontiac had, even if they were made with Armasteel rather than forged) and the deep skirt/Y block configuration of the LS means the larger crankcase has room not just for stroke (Too bad the short cylinder walls can make for piston rock at BDC of some blocks) but also handles the compression of atmosphere inside the crankcase every time the pistons race to BDC like a parachute (some blocks have holes in the main webs to let atmosphere move rather than compress). The Pontiac, of course, has a wide crankcase of its own to take a 4.25" crank.
Nunzi's in Brooklyn NY is also a great source for Pontiacs. A 4 inch aftermarket crank could have also been used in this stroker. The small bore might be questioned for airflow, but stock Pontiac valve angles are better than the Chevy small block, and most OEM use a small bore to reduce detonation from a second flame front (little room and time for it to form). The block's weak spot is its lifter bores--they aren't cast inside the lifter valley like most V8's, but just hang there and can snap off with radical cams.
Thanks for the mopping tip and your time in the service. A pro is someone who does the basics better than the amateurs. As for mopping, the other tip is where you hung the sqeezer....one side of the bucket has its wheels mounted outside the bucket bottom for a reason--so you don't push down on the sqeezer and tip the bucket over to dump dirty water over your work.
Oh, and that oil sludge? That's one of the reasons why engines died at 80,000 miles and gas stations had garages, not convenience stores. There wasn't detergent like today, there was paraffin wax and you needed to change it hot every 3K so it didn't clog up the works. Piston rings thick as your finger and few overdrive transmissions didn't help either.
Striker motors have come into their own now that there is better metallurgy to support the strain. In the old days the cast iron cranks wouldn't handle it, but the new forging system can do what the old cranks couldn't, live! Has awesome, because building high cube engines used to depend solely on the available on blocks. After decades of scrounging, there are fewer and fewer blocks available, hence the stroker! And the longer the stroke, the more the low end torque. Olds used to say Horsepower sells cars, but Torque wins races, and they were right!
All of their early engines were strokers, until the 403 came along. Then they unleashed the high RPM beast. But before that they were doing well at the track at lower RPM than their GM counterparts. The later 403 used roughly the same dimensions as Mopar's 400, and those motors were aimed at making power efficiently. The EPA mandated better fuel mileage with lower emissions than was available back in the day. Pontiac started using Chevy Motors in their cars as their engines were heavy and the Small Block Chevy wasn't. And when they weren't using Chevy engines in their cars they Used Buick V6's and some Olds engines, like their 403 and 260. The only engine they kept was their 301 which was used in the Trans Am, with a turbo. But the crank they used was missing counterweights and the block was windowed in the main webs leaving that motor weak as a kitten. Not a good design for any car, let alone a performance car like the TA!
Lou 😎👍🏽
Oh, Louis Louis, oh yeah, we gotta go now! Ah yeah yeah yeah yeah yeah! Louis Louis!
Man I always wanted this car when he finished it before he left. Also wanted project blue hair
What did they do with the push rod guides? is there a work around, had some problems finding the right Pushrods to run with it, Napa gave me some that folded over because of the contact where to the rod to the guide! Wish I knew what cam and setup that was exactly!
It's a good project. I had a buddy in the Air Force do the same thing in the late 80s. I would rather stroked a 400 Pontiac for 428 CID.
Good to see one of the less popular pontiac engines worked on. But don't the aftermarket heads work? is it just the valves are too big for the bores?
Probably
I notice that the head gasket bore is over size🤔 wouldn’t that affect the compression 🤔
It sure does. They should have used a head gasket that matched the bore. That's also a big power loss. 25 to 30 hp lost and just as much tq
To me a vehicle loses an element of authenticity when a diff power plant make is utilized so yes its great to see poncho in poncho...
Love the old hot rods my step bro has 2 68 camaros one Z28 and an SS but im into mustangs lol i have a 99 GT N/A that runs 7.09s in 1/8 mile it has a 03 crown vic police engine built out ass
Those were the episodes I really liked. Always thought Lou was their best. Other guys were good but Lou and “the demolition man” were best. Miss the old ones.
This man reminds me of pimp my ride...he should have a show called pimp my engine
