just some friends sharing some quality time in the garage helping out Carl on his birthday, we're getting dirty turning wrenches and sharing interesting 307 information
Just picked up a good running 307, gonna get an intake, some headers, and im tempted to do an e85 carb on it. Olds engines are very interesting once you dig into them
The heads on these 307 were generally crap, for additional performance supposedly Olds 350 early 60/70s 5A heads can be swapped, also the bolt holes may have to be drilled out to use them.
The Buick, Oldsmobile, and Pontiac engines don't much love and attention like the Chevy engines. It's good to see they're working on this 307 Oldsmobile.
The quadrajet is one of the reasons they get such good milage with the small primaries that was always one of the best things about the old trusty q jet that and reliability as well as drivability and when you ask for more the huge secondaries always came thru for ya and there's no other carb that makes the same moan noise as they do my buddies heard me coming for miles w that q jet moaning lol
Ya I know the sound your describing Glenn it is certainly unique and I agree they were reliable and fuel efficient thanks for sharing that's a very good point
That sound was what we as younger guys referred to as screaming in the night because thats when we would be out raising hell most of the time and that sound carried for miles and miles it seemed lol its gotta breath both in and out so anything w a cat on it or hell even single exhaust got duals w decent flowing mufflers all the way out the back straigjt pipes were just too loud for me
Thanks Mike will try and keep up with this, unfortunately our good friend Carl has stage 4 cancer but still has a desire to do what he can on the Olds so we were just helping with the heavy lifting and also there celebrating his 59th birthday
Great 👍 show and information 👏 ! I own a 1981 Oldsmobile Delta 88 with the Oldsmobile ( 307 V8 ) engine and one thing is that these engines are fairly reliable but lol noo power house .
I remember exactly what you said my father said about most of your Oldsmobile engines have a drain back issue with the oil drains on the cylinder heads seeing this engine you guys have brings a chock full of memories with my dad and i working on his Oldsmobile on the weekends
That's awesome Daniel I'm glad this brought good memories for you oddly enough this peticular engine also brings back memories for me as the owner was a good friend of mine we unfortunately lost to cancer months after this video was made, thanks for the kind words and appreciation you watching
Well thanks General_Bacon the tall fellow in the vid actually has a mobile business working on old cars only and I wish I worked on old cars only thanks for watching 👍
i inherited my dads 1984 cutless supreme it has the 307 v8 in it. its not the fastest thing. but its cool and its easy to work on. i had a 2019 mustang i was still paying on. i ended up sending that car back and just been driving the cutless. its even cheaper on insurance and for someone in college. money is tight
I'm a fan of the cutlass it was the first car I got for my son and it was nice enough to take to events and certainly the most comfortable car in the fleet to drive thanks for sharing Don 👍
Cadillac installed 307 engines in california that had port injection during some years. I learned this via CZcams. It really surprised me. Every injector was splayed to spray onto the back of the valves so it had a formed tube fuel rail.
I remember many years ago i saw the 307 on many of GMs cars buick pontiac and i saw one on a 1989 Cadillac Fleetwood brougham they were reliable in the Oldsmobile REO museum they have the very last production olds 307 v8 with all the signatures from the employees of GMs assembly line cool stuff
You have a "vin 9" 307 the one to have is the "vin Y" with the rolling cam. You can take the 5A heads and swap them with the 7A heads the "vin Y" olds had but youll have to swap the intake too cause the 5A heads use conventional style intake ports. then you got a good 307. The oldsmobile 307 was introduced in 81 and used flat tappet cam until 85 then went to roller cam in 86 then ceased production in 1990.
My mistake I thought all first gens were flat tappet and second gen was a roller cam motor being 85 and newer also I was under the impression that first gen motors had the 5a heads , maybe I should have done more results on this topic, to be honest I didn't think a video on the 307 was gunna get many views so I just touched on my very basic understanding I had of them, thanks for the comments I appreciate it
@@garythegear they got the roller and 7A heads in 86. The 307 i believe was introduced in 81 after the olds 350 rocket ceased production in 1980 and the smaller bored blocks took its place. The United states government started cracking down on emission laws in the late 70s so these "smog" engines took their place.
@@garythegear I built quite a few engines and the last one I made was 307 olds, i wanted to build something unique so i chose the olds 307 Not alot of people build those because they were viewed a throw away engine be the cost to make power was expensive and simply putting in a 350 was alot cheaper. My first car i bought was an 89 Buick electra estate wagon and that had a 307 olds and so did my fathers station wagon when i was a kid. i loved that car so the 307 holds a special sentimental feeling in me.
I finish to rebuild my engine, new intake gasket, valve cover gasket, new valve cover, new water pump, new radiator, rebuild the caburator as new, new clutch fan, new coil and wire, new spark plug, new baterrry, new thermostat, etc......change all the suspention on the car, sound like a brand new!! 50 000 miles on my delta 88, original tow color..Am proud of my duty and car...
They were so very reliable and quite fuel efficient in comparison to other options of the same era , I also have fond memories of long road trips in similar vehicles and actually find them more comfortable than new cars, thanks so much for sharing you just reminded me of a simpler happy time
I have a 1983 cutlass with a 307 olds. 200r4, 2.93 rear gear and i get almost 25 mpg on the highway with the ac blowing. Lol. It's not a speed demon, just a pure highway cruiser. 2nd owner of almost 30 years, never had an issue with the motor.. very strong.
or any what they call small block olds motor a 350 rocket would do very nicely in that and probably be a better choice than the 403 in my opinion actually the 403 was ah ok but kinda doggish where an older 4 barrel rocket 350 from an old cutlass or vista cruiser or somsthing would be a screamer bet or you can always go the easy way because im sure the holes are drilled in the frame for the mounts a small block Chevy will bolt right in as well just as easy and much cheaper also could be hopped up cheaper too w even exhaust manifolds and just dual exhaust flilowmarwers or somsthing it would sound right and be a really nice cruiser for the cheap if you did it right
Sorry I don't have any leads on parts for the 307 olds but hopefully some sees your comment here and points you in the right direction thank you for watching
has the 307s had any issues with missfires? my 84 olds 98 has a 307 and at idle and lower rpms when driving i have a noticable missfire and i can't figure it out for the life of me, good compression, new wires, plugs, carb, rotor, cap but still gas the miss, good running engine when it's driving, but holding lower rpms and the miss are stumping me lol
No they never had known issues with misfire that I'm aware of , I can tell you that some of the new stuff we buy today isn't that great like plugs wires etc all I can say without seeing it is keep digging you will find it
put a new distributor in it that has an issue w the magnetic pickup or something they are pretty cheap for a brand new one if its still skippy after that hmu but im thinking you'll be good w it and it will wake up too the advance will all work right ans all that w the new distributor
i just took mine off my 84 le sabre made alot more room now i think my power steering belt is bad squeaks like hell even when i adjusted. Any website you fine for Bumper fillers let me know
84 307 (5A) I deleted mine got a bad squeak after replaced water pump,power steering pump, belts, Now my power steering /altenator belts wont line up need some pointers been at it for 2 days jammed up
Not alot you can do with the 307 I understand the earlier version 5A heads flow better and they were also the flat tappet cam style that produced a little more power, primarily these were created to be more of an economical engine and were guite reliable pre fuel injection deals , I did come across some other channels on CZcams that are very well versed on these little engines
@@garythegear ok thanks for the info Im gonna buy a custom cruiser from 1983 307ci I don't wanna muscle machine but a little more power To get along with the traffic Im from the Netherlands Thanks for the info
All it needs is some new Eternal parts like aluminum intake manifold any 600-750 CFM carburetor new pushrods lifters rocker arms some honing the cylinder walls new pistons connecting rods new crank and more so i can look fresh and run better
Couldn't honestly tell you, it had been passed through many hands and was slatted for many different projects that never happened, in the end my good friend passed away before it could be installed in his olds so it was sold off
After years and years of searching I finally find information about the 307 Oldsmobile but now that I know I have the worst of the two since mines in 86 now I’m lost. I thought I could just buy aluminum heads intake a new cam and headers is that possible
Unfortunately I'm not sure that there's any aftermarket parts available for the 307 olds, all I know for certain if your going with a 307 of any kind the Oldsmobile was the better of the bunch , you'll have to do some reasurch on this one I'm sorry I don't have a solid answer for you , the information I was given several years ago that not much of anything was available
LoL I wonder if the women in the background were thinking why doesnt he take the mounty thingy out of the engine stand thingy to mount to the engine thingy and then bring the engine stand thingy to the motor mount thingy to mount easier?? 😂
Unfortunately the owner my good friend passed away before it made it into the car however the little 307 was sold to a young fellow that needed it for his olds cutlass, so it went to a good home
There was also a High out put 307 180 hp in the 442 and the regular 307 had 140 hp respectively.Whats the cam difference in the 84 and prior years and whats the benefit of it? The carbs were set set on the lean side at the factory and sealed so you couldnt adjust it , I guess it was for emissions and fuel economy.I heard you could tap or drill out those mixture screws so you could adjust for more power response. I had a chevy 307 in a 1968 Impala it had 200 hp! with a power glide tranny.That 307 replaced the 283 engine. People make fun of the olds 307 I happen to like it. I am a G Car Guy! That engine looked pretty dry.
Yes I think that peticular motor sat for a number of years, we didn't have alot of information on it the difference in cams was hydrolic flat tappet in the older version then mid way they went to hydrolic roller cams , there's alot of interest in the olds 307 engines personally I think they were the best 307s made
I had a 85 cutlass my first car as well with a 307 I got it with horrible blow bye but still drove it for 5 years and it only let me down once and needed a trans and the motor rebuilt and I just ended up selling it I always wanted to restore it but wasn’t ecomical
There certainly becoming popular today, back in the day it wouldn't have been a smart financial decision but today they certainly are gaining in value and popularity
I think you got that the wrong way around ! The roller cam version is so much better , anything with roller cams is smother, lasts longer and more power . Every V8 today is roller cam
Ya I think the plan in the day was to provide a fuel efficient and reliable engine , not much one can do to modify them unfortunately but they were certainly bullet proof thanks for watching 👍
I've seen some rather stout 305 chevys but thats only because they are in the small block Chevy family and things fit from one engine to another cams heads etc unfortunately the same.is not.so true w the 307 olds motor there is way less aftermarket support for the poor girl hence making upgrades performance wise not as easy or common the heads as I said are the biggest issue shrouded valves due to small cylinders one of the biggest issues people have found ways around that issue of course and although not as desirable as a 350.the 305 has found its way into the engine bays of a lot of decent performing cars it has more limitations than its big brother the 350 but with some finessing can make some really really good power at a low cost compared to an olds motor due to as I said the aftermarket supply and the interchangeability of parts
I’ve seen quite a few 307s start knocking after 3 seconds of valve float, also heard people claim that they’re a tough motor, not really sure what to think of them
Well valve float on anything is not good, I personally have always been into the hot rod or hot rod able engines like big blocks or the 350 however there seems to be a big following for these little engines and I won't argue with anyone about their reliability, each to their own I guess
No worries I never expected the interest in this little engine we basically went over to Carl's to help him out as you saw in the video and I thought it would make for boring content if I didn't arm myself with a little information on these engines and then to my surprise there appears to be alot of interest in them , anyway thank you for watching I appreciate it
I won a $100 bet on the ole 307. My drunken uncle (who worked at Olds for over 30yrs) told me a 307 was a Chevy engine. I said, I'll be you $100. Oldsmobile had made a book just around that time on a lot of Olds history, and given them to it's employees. I told my uncle go grab that book. I opened right up to the 307...give me my $100! Chevy guy betting an Olds guy about Olds engines. 🤣
We need more Olds 307 rebuild videos they're not powerhouses but they are reliable asf!...so itself warrants a rebuild and they're good on gas!
I agree good reliable little engines for sure thanks for watching Nathaniel 👍
@@garythegear anytime brother!

Sorry I should clarify it was the last of GM carburated cars thanks for sharing that 😀
The 307 was last FOUR barrel carburated engine. The 5.8 ford had a 2 barrel.

I think you got that the wrong way around ! The roller cam version is so much better , anything with roller cams is smother, lasts longer and more power . Every V8 today is roller cam
Those and the 305 Chevy were idiot proof practically due to the heads not flowing enough to let it over rev and blow itself uo
Ya I think the plan in the day was to provide a fuel efficient and reliable engine , not much one can do to modify them unfortunately but they were certainly bullet proof thanks for watching 👍
I've seen some rather stout 305 chevys but thats only because they are in the small block Chevy family and things fit from one engine to another cams heads etc unfortunately the same.is not.so true w the 307 olds motor there is way less aftermarket support for the poor girl hence making upgrades performance wise not as easy or common the heads as I said are the biggest issue shrouded valves due to small cylinders one of the biggest issues people have found ways around that issue of course and although not as desirable as a 350.the 305 has found its way into the engine bays of a lot of decent performing cars it has more limitations than its big brother the 350 but with some finessing can make some really really good power at a low cost compared to an olds motor due to as I said the aftermarket supply and the interchangeability of parts
Well said Glenn that's exactly the case 👍
I’ve seen quite a few 307s start knocking after 3 seconds of valve float, also heard people claim that they’re a tough motor, not really sure what to think of them
Well valve float on anything is not good, I personally have always been into the hot rod or hot rod able engines like big blocks or the 350 however there seems to be a big following for these little engines and I won't argue with anyone about their reliability, each to their own I guess
Why is the earlier 307 better? You kept saying but never explained why
The earlier one was the higher horse power version, nothing wrong with the newer version just down on power
@@garythegear oh I see. thanks for the reply!
No worries I never expected the interest in this little engine we basically went over to Carl's to help him out as you saw in the video and I thought it would make for boring content if I didn't arm myself with a little information on these engines and then to my surprise there appears to be alot of interest in them , anyway thank you for watching I appreciate it

You can get cancer from everything including food, drinks and medication.
I won a $100 bet on the ole 307. My drunken uncle (who worked at Olds for over 30yrs) told me a 307 was a Chevy engine. I said, I'll be you $100. Oldsmobile had made a book just around that time on a lot of Olds history, and given them to it's employees. I told my uncle go grab that book. I opened right up to the 307...give me my $100! Chevy guy betting an Olds guy about Olds engines. 🤣
Cool story thanks for sharing 👍
