Yeah buddy you got it =)
@@What.its.like. I saw him live in the Cotton Bowl in Dallas,Austin and New Orleans 👏👏 Great Show Everytime 🤠👍
Oh wow that’s awesome I just found out he was in his early 30s when he died in a plane crash wow what a bummer..
@@What.its.like. Helicopter crash .
Awesome ! @@What.its.like.
One note, Pontiac Straight Side Valve 6 and 8 Cylinders were nicknamed the 100K mile engines in their day. Part of it was due to their rugged high chrome blocks (Similar to Packard and Studebaker) but Pontiac engines used a oil sump strainer system that ensured all oil was strained before entering the bearings and it also allowed complete cleaning of the strainer when oil was changed. This oil strainer system was similar to that used on many early Farm Tractor engines as well!
Thank you so much for adding that information =)
The 1950 owners' manual extolled the virtues of their "oil filter system"("precipitation"?)but I don't think it did much except possibly reduce the possibility of visible size metal shards or scarf getting picked up through the strainer. I think there was an aftermarket Fram bypass oil filter system that dealers could install on the cars as a dealer installed option.
VWs had a strainer like that. I have an add on oil filter made by AC that was in a box of auction stuff I bought. Fits any GM car of that time. Also in that box was an original Model T jack and an original Zerk grease gun.( as in Zerk fittings.) You filled it with grease and there was no pump. You just screwed the long T-handled shft in slowly and it forced the grease out the Zerk fitting nozzle. All for $2 'cause no one else wanted the box of "junk".
WYR: 1933 Pontiac and 1953 Pontiac. Great coverage as always, of the only Junior model to outlive its "big brother". Thank you ~ Chuck
Thank you glad you dig this episode ( this is the second time I tried doing this engine family months ago and hit a road block, but was able to find what I needed this go around )
Great choices =)
In 1957 when I was 12 years old, my folks bought a 1954 Chieftan 8 wagon six passenger with Hydramatic and with 34,000 miles from a dealer in Rhode Island. 5 days later, we loaded it and drove to Los Angeles, California. It was quiet and smooth, and fully loaded it drove fine at 60-65. With the exterior sun visor, when a large truck or bus would pass by us on the opposite side, that visor would catch the wind and physically one could feel the car slow down from the additional wind drag. The only problem was crossing the desert in August in the day time, it did overheat, which was not uncommon in those day. It was pretty large, especially compared to Chevrolet, Ford Plymouth, Mercury and Dodge wagons of the same era. We had it until he sold it in 1961 and bought a 1959 Catalina wagon, 8 passenger with the 280 hp 389 two barrel and hydromantic. That Catalina was quick for a 4,400 lb car. Curiously, the Bonneville of the same era had better highway mileage with the same 3.08 rear end. Probably because the primary barrels and jets on the Bonneville were smaller than those on the two barrel and used less fuel at cruising speed. Open "Niagara Falls" and the other two barrels made up for it.
Cool story
34 Pontiac
49 Pontiac wagon
As a kid I always looked when I saw a Pontiac coming and would count the stripes on the hood to tell whether it was an 8-cylinder or not.
Great choices totally agree that time period You could not tell what was under the hood
love the straight 8. Gotta say that 33 pontiac is super sweet. The wagons were all just as good to me.
Awesome choices =)
Another great engine family review, Jay. I'm glad that you create these, as they are wonderful quick reference tools. Keep 'em coming!
=) glad you dig this episode
I will take the Red one. Thank you for sharing with all of us.
Sweet glad you dig this episode =)
I had a 1954 Pontiac Chieftain Deluxe with a straight 8 and hydramatic drive. That car was a tank and nicknamed "Betsy".
Those things were a huge beast! With the straight 8, and slush box transmission, yet it still moved under it's own power! 😂
What did you think of Betsy?
@@What.its.like. She made 0-60 measured with a calendar, LOL! She was a bit rough, but easy to work on. First point ignition I worked on. Eventually, the #2 and #7 exaust valves broke. That was her demise, nobody would agree to fix it. Sold for a few hundred to someone who wanted the hood ornament.
Thank you so much for sharing Betsy with us =)
Pontiac and then the 49. Good short video.
Love this well done episode on the Pontiac 8. Great information.First pick the 34 Pontiac, the second I'll take the 49 Pontiac sedan delivery even though it is not a wagon.
Like to answer the question you asked in the Marlin video on the twin stick, and 2 speed rear axles. With automatic transmissions and computer controls we won't see these features in today's cars, but it would be neat if they did. Personally I would like to own a Twin stick AMC car, it would be fun to drive since I prefer manuals, the Twin stick transmission to me is similar to large trucks with 2 stick transmissions. some Mack trucks has a 5 speed main transmission, and a 2 speed auxiliary transmission, so AMC had the same concept. Ford cars before 1949 could be fitted with a Columbia 2 speed rear to give you 6 speeds. It would be nice if the auto mall had one for sale that would be a great car to feature.
Awesome choices it was going to be wagons in the second scenario but then came across that picture of that sedan delivery and was like THAT haha neglected to change the voicing
Awesome insight to the Marlin twin stick thing
You can't argue with Boss Kett.
Yeah =)
1935 is good but my favorite is 1937 6 cylinder.. shorter fenders and hood more per portioned 🤔 ??
My grandfather had a 51 Silver Streak 2 door fast back .. Pontiac flatheads ran smooth 😊 .. But Packard had them beat by a mile 😉👏👏👏👏
I've driven a 29 Oakland .. Full size and long but ran smooth and rode comfortably 👍😉.
Great Episode
Happy Motoring ✌️🤠
Awesome that 51 silver streak fastback what a car =) great choice
I really wanted to cover an Oakland before the year was over just didn’t get it oh well there is always next year
The Packard Straight Eights were larger,some by a lot,and also I think some of them were hand balanced (crankshaft and piston/con rod assemblies)
The Oakland V8 was NOT shared with the Viking. They had their own V8. It was the same displacement, but was not the same engine.
Awesome I saw conflicting information about that what to cover those in an engine episode one day were they supplied by Northway?
I can't pick a favorite jay I want all 6 of these
They were all nice =) that sedan delivery was epic
1934 & 1949.
Always liked the 'sedan deliveries'...with an air mattress they'd make an awesome tour car.
I've neen watching "Big Bang', the follow up series to 'Young Sheldon', and in the beginning
of the show, there're a gazillion photos, from 'the bang' to present, on screen for half a nano
and in the middle, there's a tan 1941 Chrysler barrel-back station sedan.
wow insert bearings and pressure lubrication? unheard of in the lower to middle cost field ranges.
Crazy right
I like the 33 Pontiac, and the 49 pontiac
Sweet choices
I am not expert on Pontiac engine, but Ithink there is a "typo" on "249" engine. With shown numbers the engine displacement would be 558 ci. It is not a criticism, I just have Pontiac 268 ci engine and I noticed that bore and stroke for "249" would be bigger.....
I enjoy watching your videos about engines.
Yes that is a typo I’ll have to see what the actual size is thank you so much for pointing it out =)
Had a hand-me-down 1951 Catalina stick-shift in the late 1950's; was a weak contender compared to the Olds V-8's of the day and used lots of oil. Thought it was time for a rebuild after a Dodge 6 ran circles around me so pulled the head and found every wrist-pin loose and grooved each side of the cylinders. Went to the bone yard and picked up a 1954 Olds 324ci; with the help of Hildenbrandt adapters, it went into that sick '51 and then she was good to go...
Another cool video, for the wyr my choices are the 34 Pontiac and the 49 Pontiac maybe it’s just the color but my choices are totally based on looks
Awesome choices =) straight 8 Pontiac is my favorite era of Pontiac especially love the late 40s early 50s
I'll take the '35 and '40 Pontiacs. As a side note; @2:59 that's a '35 not a '36 as inferred. The '35's light pods were mounted vertically to the fenders,
whereas the '36's light pods were mounted horizontally to the side of the grille shell
Awesome sweet choices thank you for that correction =)
WYR: All of them.
All cars from back then were generally made better than they are now.
Sweet choices totally agree
35' Pontiac, 53' wagon, SRV Texas Flood
Sweet choices yep that’s the song and band
Unknown to many is that Pontiac had intended to equip the new 1953 models with that 1st V8, but strong objections from Olds, who had a lot of clout in GM, forced Pontiac to delay the V8 until 54, then 55. Oldsmobile thought Pontiac was becoming too Olds-like.
Yes thank you for sharing that information
Hi Jay!: Those Pontiac Eights sound like they were nice sturdy, relatively powerful engine! No wonder they didn't want to change to the V-8! WYR#1 1934 #2 1940 that one is SWEET!
Awesome choices =)
I want to drive one some day
Nice video! You could have covered the non split-head straight 6 in this video since it's design was based on the straight 8. Now I'm looking forward to you covering the early Pontiac 6's!
Yeah definitely going to do a video on Pontiac sixes as well as the ohc in the 60s =) glad you dig this video
I once looked at a 1953 Pontiac wagon for sale. It had been sitting for quite some time, so that by the mid 1980s when I saw it, it was in sad, sad shape. It did have a Hydramatic transmission.
53 is one of my favorite Pontiac wagons of all time I love the tin Woody.. I’m sorry it was a derelict shape
1933 Pontiac and 1953 Pontiac. The 1954 Pontiac Star Chief had a longer rear overhang and a much larger trunk, for one year only. Your numbers for bore and stroke for the 248.9 CID engine are way off--not just a rounding error--they give 557.6 CID. The later-listed figures for the further-enlarged engine are actually smaller. The CID figures still don't match with them, but they are far closer.
Great choices thank you for pointing that out I got the information here but it’s clearly wrong
www.conceptcarz.com/s25856/pontiac-chieftain.aspx
Also, not all 1950 cars had the new 268 cube engine. Some came with the 248. That's why the horsepower rating is only 108 on the 50. Better that some cars had MORE than advertised horsepower.
Thank you so much for adding that clarification =)
Chevrolet, Buick, Oldsmobile and gmc had over head valves during this time. Strange they Didnt change , but these divisions were like separate companies. The company could have saved millions by integrated manufacturing.
If someone is lucky enough to get to drive one of such cars,it would be a good idea to not try to reach high speed or high RPM in it,at least until it could be determined that the engine does not have "ridges" at the tops of the cylinder bores due to wear (the wear does not go all the way to the very top of the bore leaving the ridge) at high RPM the connecting rods stretch a tiny bit allowing the top piston ring to strike the ridge causing failure
I think I have heard of such cars (including such as Dodge) being sold by owners who drove conservatively to someone who took the car out to "see what it would do" and promptly suffered a completely destroyed engine with a broken connecting rod or broken crankshaft.
Great information thank you so much for sharing that =)
Great vid!
Thank you glad you dig
@@What.its.like. 👍👍
I see the '46 car had cast iron pistons! Really want to keep the RPM down on that ! Pretty sure that the lighter (and easier on the crankshaft at speed) aluminum came in soon after
I'd go with the '35 coupe & the '49 wagon.
I had a '38 2 dr 6 cyl sedan 3-speed standard, a '50 4dr Streamliner 8 hydramatic & a '51 4dr sedan 8 hydramatic. Was forced to sell the '50 Streamliner & regret that to this day.
pontiac inlne eight kool!!!
Sweet
According to the 1950 Owners' Manual the bore/stroke for the Eight: 3and 3/8" by 3and 3/4"
for the Six: 3and 9/16" by 4"
has a statement that external oil filters are not needed but I believe that they were available and extended engine life if the cartridges were kept changed
based on what the car would do (it had a 3 on the tree with a heavy clutch) the 108 horsepower was considerably understated,probably because of GM policy that tried to steer buyers to the more expensive Buicks and Oldsmobiles (although I think Oldmobile's claimed 135 horsepower was also understated in deference to Buick and Cadillac)
I believe the Pontiac would handily outrun the smaller Buick Special with its 248 Straight Eight,at least as far as low speed acceleration
at least two people claimed that this car (1950 Pontiac) reached 100 mph
it was quicker from a stop than a '54 Dodge with a 170 hp. Hemi (although once speed built up and the limitation of the pitiful 2 speed automatic in the Dodge was overcome the Dodge would pull far ahead and leave the Pontiac far behind on the highway)
I believe the Pontiac once embarrassed an early Corvette from a stoplight (before Corvette had a proper engine, just a louder version of the shake,rattle and roll "Stovebolt")
Thank you so much for that correction this is were I got that information clearly a typo it’s my fault for taking that at face value I should have checked another source
www.conceptcarz.com/s25856/pontiac-chieftain.aspx
I have never seen a Viking vehicle before but l remember seeing a 53 Pontiac with straight 8.
The 37 Model is my favorite that needs a 455 HO installed
I wanted to cover one so bad before the end of the year but come to the realization that it’s impossible to cover every single brand in a year going to definitely try to do one next year I would love to find a Marquette as well did a couple la salles still need to do an Oakland as well
I liked the '35 and the '53.
Awesome choices =)
Love alll the coupes and wagons but if I had to choose 1935 coupe and 1949 wagon
Awesome choices =)
Looks like the car at 5:20 has a 12 volt conversion (the original battery was long and slender,I think 17 or 18" long,and larger/higher amp hour capacity than common 6 volt batteries of the era (Buick 320 and Packard engines might have also come with similar batteries although I had the idea from somewhere that Packard once tried an 8 volt/4 cell system
I’ve wondered why some batteries from that era are long and slender
The 232 version made about 150 lbs. ft. of torque.
Awesome thank you for that information
I'd say '34 and '54 Pontiac, even though, the '49 is also pretty nice...
Cool choices =)
4:24.i have a legitimete question.how can a 249 cube straight 8 have larger bore & stroke, plus 2 more cylinders.& still be smaller cubes than a ford 300 6 cylinder? a misprint? wouldnt your bore & stroke numbers make it over 500 cubes for 8 cylinders? what am i missing?
Different engine architectures fiat made a four-cylinder that was 28 L..
4.3 inch bore and 4.8 inch stroke....that's bigger than the 500 Caddy (4.3 inch bore and 4.304 inch stroke)
The figures at 5:00 can't be right--compare with the bore and stroke of the Ford 460 !
Yeah that one is a typo thank you so much for pointing that out.. I’ll have to see what the actual bore and stroke is lol
@@davidpowell3347 Ford 460: Bore 4.351 Stroke 3.85 inches
Ballad of Curtis Lowe, by Lynrd Skynrd.
Yeah buddy you’re the first one to get that at the very end
I’m confused. I believe the Bore and stroke listed for the 248.9 engine are incorrect. Due to the fact that a 4” x 4” v8 was made by Ford which was a 400cid engine. Also the next engine described in the video has a larger displacement , but the both bore and stroke listed are smaller that the bore and stroke listed for the 248.9. I imagine it’s a misprint.
Yeah that’s a typo this is where I got the specs they are real hit and miss as far as information goes
www.conceptcarz.com/s25856/pontiac-chieftain.aspx
@@What.its.like.I would imagine the most accurate information would be found in the brochures.
I get most of the information from the ads some of them did not give engine displacement though and finding advertisement pieces with every single engine from this engine family was really hard there was a couple engines that wasn’t advertised..
The 1937-49 bore spec was quoted from a dyslexic source. It was actually 3.4 inches, not 4.3” (which would be impossible without a total retooling).
The reason they finally went back to V8’s was to enable wider bores without ending up with a 40 inch engine length.
I'd take the '35 and the '49 Pontiac!😎
Sweet choices =)
I am curious as to whether all of these Pontiac Straight Eights had the same external dimensions (same block) or did the block change? Also was the Pontiac Six the same thing except with two cylinders removed from front and/or back of the casting or was it lighter in cross section construction? I do believe that as of 1950 the displacement per cylinder was larger in the Six vs. the Eight. I think the Eight had a shorter stroke. Also I think its stroke was shorter than such as Dodge and Plymouth sixes giving it (also had a 2 barrel carburetor) more RPM capability. Although with all such engines it was dangerous to run them at as high RPM as they seemed to be able to pull to.
The 249 was a typo I got the specs from this site
www.conceptcarz.com/s25856/pontiac-chieftain.aspx
That first Straight 8 made about 140 lbs. Ft. of torque, not 116.
Thank you for that correction
Grand funk
Dump a V-8 for a straight 8. Talk about snatching defeat from the jaws of victory. Oh well, Henry Phord hated hydraulic brakes, had to be there I guess.
Crazy right?
Hi Jay
Did you get my picture?
Finally it took forever to download I wonder how much the met is
1934 Pontiac
1940 Wagon
Sweet choices =)
My parents bought 2 brand new cars that I remember but the first was a 54 Pontiac coupe with the straight 8. Since I was a kid, I remember 2 distinct things about it. The first was the round chrome grill in the dash. I thought it was for the heater, but was the speaker grill. The second was the illuminated chief's head on the hood ornament. I restored a 54 Pontiac radio on my channel. Here's the link for those interested - ruclips.net/video/p6o9pJasGGU/видео.html
Sweet thank you so much for sharing that link you did a stellar job restoring that and it sounds great
😊
35 Pontiac
53 Pontiac...
Sweet choices =)
Why did Pontiac want to switch from a V8 to straight 8? What was the advantage?
I guess it was cheaper should’ve done that engine episode first the V-8... Maybe that will be next week’s topic I don’t know yet
1935
Sweet =)
@@What.its.like. Have you covered the International V8’s?
Not yet will one day =)
learn how to pronounce the "st" blend. There ain't no damn H in it!
We all say things different
Dad had a 6 cyl 51 Pontiac not much on acceleration. Armstrong steering good to take stuff to the dump so you didn't dirty your real car dad never paid more than 100$ for a car so he tested a lot of rusty orphan cars 🦾
Haha great story thank you so much for sharing that memory with us =)
@@What.its.like. there was a 32 roadster ford convertible pickup V8 dual side mounts I was 8 yrs old I brought dad to the scrap yard we rode it around they wanted 35$ for it dad said it smoked wasn't worth it watched them burning it up today 30k $ I'm 81 yrs old I'd still have the thing 👾 thanx for your resp. Have 1000 stories 🙄
