In this video, I take you through the full reassembly of the Oldsmobile 350 Rocket from my Cutlass. We go step by step on putting it back together, all the way up to the intake. Thanks for watching! - ยานยนต์และพาหนะ
Excellent video sir. Looking forward to the start up!
Chad. Great video man! Getting ready to jump into my first rebuild and your video gave me a ton of confidence with this process. THANK YOU
You are very welcome! I am hoping to do more videos on my Cutlass this summer when I get it out of storage. Stay tuned!
Instablaster.
So Troy, how'd that rebuild effort turn out?
Thank you for posting. Rocket power! Informative and the story is told in easy to comprehend detail. I am subscribing.
Thanks man! I am hoping to do more Cutlass videos this summer! :)
Great video now i m ready to do my 455 engine
Dope work Chad! Definitely helped me out a lot.
Glad to hear it! Thanks for watching!
Excellent video. You and I have the only 350 videos on TH-cam but yours came out alot nicer than mine. I had to use a cell phone and I had practicality no editing tools. It's too bad they couldn't give you the higher compression pistons, apparently they're hard to come by. Also I love the paint scheme, cast water pump, black bolts, black balancer etc. The 161 stamped into the back of the block translates to June 10th as it's the 161th day of the year.
Thank you!!! I too shot it on my phone with a hell of a tripod and a lot of editing lol I watched a few of your videos on you channel, I really like them and wished I found them before my tear down and rebuild. Again, very nice rebuild.
Chad Williams thanks for swinging by. I'm interested to see how the rest of your project goes.
It will be a long project, probably about 5 years. Lots and lots of body work to do! Need to save up some money for it lol Good luck on yours!
The high compression 6cc pistons are readily available in .30 over
Great video!!
I always liked the Olds Gold but around here it is hard to find that right color! But I am just glad I didn't need the Oldsmobile Blue paint, after I realized just how insanely difficult the gold was to find!!!
Yeah, the gold wasn’t easy to find. I had to go to a speed shop near me to find it. Glad I did. I bought a couple extra cans when I did :)
have to do mine
Thanks i needed this video
You're welcome! Glad I could help!
Thanks great video
Thanks man! :)
nice video bro. wish i had an extra hand so i could pull my 455 out and get it rebuild.
It sure was a chore to do it by myself, but it is totally worth it once it is done :)
Nice rebuild. I have an original 68 low compression 350 in my Cutlass. Only thing I would do different is switch the high compression 6cc Pistons. Combined with a 4bbl that should engine is rated at 310 hp from the factory
I got a 69cutlass 350 motor how can I tell if its a 350 rocket
David East number on the block by oil fill and if its a gold engine
psstplease put the W31 flat top pistons in it and the W31 cam from the 1970 W31 cutlass 325 hp
Ima bout to do the same to my 72 cs
Great video Chad. I was wondering if you had any alignment issues with the crankshaft and water pump puliese?
allways use selac indain head sealer on the core plugs / mondello has a great book on olds rebuilds they sell great olds parts to i am building a 403 to replace the 307 in a cutlas 84 model both are smallblocks i have rebuilt many engines of all types good job love your homemade cam installer !!!!!! dbn
HIGH GUY I HEARD YOU TALK ABOUT THE ROPES IN YOUR GASKET KIT FOR THE BIG CAPS BUT DIDNT SEE THAT APPLIED
Did you do a factory stock rebuild on this motor or performance build ?
There are a lot of tricks that you can do on those motor's to make a lot of horse power your cam bearings were they oil restriction bearings or did you put oil restriction into place the ones that go into the block ? Olds motors need to keep the oil in the bottom end ...
As well anouter trick for 7 horse power is the exhaust sides of the heads the center ports are close together with that little indent between them if you fill that indent in and totally separate the two ports that is 7 horse power ... There is another way to make more horsepower on the other side exhaust at the intake side but requires a bit of work as well ...
Good luck with your project 👍
You dont have to check the thrust bearing play on am Oldsmobile motor w a dial indicator moving the crank back and forth ?
Beautiful job. Really like the gold color I think the black folks would look excellent can't wait to hear it running! Truly a beautiful engine
Do you mean black bolts not folks? haha couldnt help it had to comment
What part number for intake manifold and carb did you use? Trying to find a good combo for my 72 cutlass supreme. Thanks 👍🏼
That is one of the best V8s . Alot of people swap these out for 455 but i would never do that!
Why
@@cedricwaller4373 cause it's not necessarily
I have a 1977 cutlass 350 rocket i was thinking about putting a 455 in it was looking for some extra power is there any cheap mods I can do to boost horsepower and torque
@@cedricwaller4373 maybe get some ram rod heads or get something close to them! Ram rod cars were mid to low 13sec cars which alot 455 cars never did!
@@gshock3092 and thoes heads will fit the 77 rocket motor
looks like stock heads with stock components - springs, rocker arms, probably push rods. The Thumper Cam with that lift and duration should have a double spring set up that Comp Cam recommends and sells as a kit. Rev that engine to 6K maybe a hand full of times, might be lucky before bending push rods floating valves or ingest a valve into the bore.
With all due respect, not to insult you but your video title is misleading - what you did was a re-ring not a rebuild.
I didn't notice maybe I missed it, if you replaced the oil pump while you had the motor torn down at the very least polished the crank and installed new main bearings.
Rebuilds always involve machining the block and heads, and magnafluxing to check for cracks.
I wish you good luck with your car projects and good health, young man.
ps.... Most local auto parts stores that rent tools also have the cam bearing installation tool available for less that $10 per day.
Did you ever find the torque spec on the fuel pump eccentric?
Hey good morning. I’m putting in my 7111 intake today and have a 1406 carb, will I need a spacer with it or will I be able to see that as evident prior to putting it on? Thank you.
I’ve got a rare bird. I’ve purchased a 1980 C10 that came stock with a 5.7 Diesel then GM swapped it out with an Olds block of 395558 2 5.7 Gas engine. So this olds stuff is all new to me. It’s a little different animal but boy does she run good. Thanks for all the great videos.
I think you needed an align bore on the main bearing caps. That plasti gauge should have spread evenly across it. You had large sections of it in the center of the bearing that did not crush at all. This indicates out of round caps.
Caught that also. This is so important rebuilding engines this old same with decking the block using a torque plate/hone ck lifter bores etc.
Fav is a stellar balance job, everything. Longevity is where its at for me just knowing everything is right and dont cost that much more.
When you put the new timing chain in did the instructions tell you to put the timing marks in that way i think the Chiltons book shows them different. I’m installing mine and I just want to be sure.
Great rebuild by the way. I’m finishing up my 403
Hey Chuck! So, the Comp Cam instructions said to put it that way since I am not doing some crazy race engine build. The other way would put some major advance or retardation to the engine.
Ok thanks for the info Chad looking forward to seeing it run
Does the front main cap implement a rope seal?
I didn't see you put in a thermostat. Did you put one in?
HIGH GUY CAN I TAKE OFF THE TIMING CHAIN COVER WITHOUT MESSING WITH THE OIL PAN I BELIEVE I NEED TO CHANGE THAT SEAL IN THE COVER. IS THAT WHATS CONSIDERED THE MAIN CRANK SHAFT BEARING SEAL???
I just need to know if there''s a freeze plug behind motor mount drivers side on my 350 rocket 70 olds cutlass?
Hey, I just went and checked, there is not a freeze plug behind it. They are just to the left and right to it.
What book are you referring back to cuz I'm working on a 350 rocket and I was curious
What comp cam kit did you use?
Where did you get your gasket set
what size bolts do you use for the engine stand
What size pushrods did you use?
Do you have a video on honing the cylinders on the Olds 350?
Hey Real With Self, sorry, I don't have any videos of me honing the cylinders. But, I used a basic dingle berry honer and kept things lubricated with oil while I was honing. Hope this helps!
Thank you appreciate it
Im having a hard time getting the starter back on. Keeps getting stuck in between the exhaust pipe and block, not sure if you're having the same problem. Any tips? Thanks
So, I actually installed my starter before putting my headers on. The starter is ridiculously heavy, so fighting it against the exhaust manifold is no fun. If you can get the exhaust manifold off, that may be your best bet. Good luck!
I’m rebuilding the same engine, What kind of headers are those? And do you know where a motor mount starter heat shield shroud goes? I can’t find a picture anywhere, it’s the original one and all I can find are wrap style shields 🤦♂️
Please tell me you used fuel hose to cover the rod studs from marring the cyl walls!!
Nah, I didn’t put anything on them. I just made sure not to touch the walls. ;)
Did you put on new piston rings?
always buy the non ethanol boat gasoline usually sold near marinas in gm cars or have a dozen fuel pumps in the trunk.
Ethanol gas is garbage ruin small motors like lawn mower etc.
Ethanol will dry out gaskets, diaphragms power valves real quick if they sit for periods of time not running .Otherwise they do ok with ethanol gas although non eth would be ideal .
Here in Ca I dont know where one could get non ethanol...were stuck wtih pump.
I Use 91 and a can of Torco or VP to spice it up
@@gordocarbo they did it on purpose to get old cars off the road had to find a way to kill them cuz they were lasting too long fortunately it destroyed enough boats that insurance companies forced the refineries to offer non-ethanol gas anywhere there's a lake nearby. I filled my car with non-ethanol gas and my diesels will run on an oil gasoline mixture a used engine oil diesel fuel gasoline and a tiny amount of acetone add filtered for less than a dollar a gallon. East Coast gasoline runs around $3.50 a gallon for non-ethanol I'd never move out west not with the migrants and the high cost of groceries and gasoline and mortgage rates
@@VintageVaughnVehiclces Im in a poor area of SoCa had to move out of LA county...87 octane yesterday was over 5 a gallon. Bread is $5 a loaf....I aint making it kinda scary.
How would it cost to have a Olds 400c.I. engine?
Going back stock , do you still need to measure bearing clearance?
You should measure it if you care about it working without any issues after assembly...
Wonderful video Chad. I'm in the midst of rebuilding my 70 cutlass 350 and was wondering if you may be able to help me. I am having difficulty figuring out the hosing behind the carb. Could I send you pics of the area I am talking about? Your help would be appreciated!
That hose plugs into the #6 spark plug Roy!!
Will those brass freeze plus turn blue or black from heat, can they be painted with the gold after installed ?
Sure they can. Never seen one turn color due to heat though.
what heads are on this? 7A ?? How much hp do you think this motor will produce? I have a 73 olds cutlass with a 350 and want to rebuild it. Does the thumper cam work with the original stall converter and a/c..... thanks
If it were me Id be calling Isky or Crower to be steered towards the right cam for you .Too many choose by popularity, a video clip and are disappointed.
Was your cam for 45° or 39° block.
The line should read the Black bolts would look good. The speech to text engine is not so good on my phone
What size ate those v belts.
Any video of her running after rebuild?
I will be sure to get one this spring. I have a video of it after the exhaust was done, just waiting to get a better one. :)
Hey, 2 questions: trying to start the car up but having a difficult time getting the timing right. Any tips on how to set it up properly? Also, not sure if you can send me in the direction of a correct firing order diagram. My other question is how to you adjust the power steering pump to get the belt on? Thank you!
Hey there!! For the timing, you will want to buy a timing light and timing tape. I bought my light from Harbor Freight and my tape from a local speed shop. You will want to point number 1 sparkplug wire on the distributor towards the number one cylinder. Also, make sure the engine is at top dead center and on the compression stroke (not 180 out). If all that is good, you should have your timing on zero. Since the Olds distributer spins counter clockwise, you will want to turn your distributer clockwise to advance the time (I believe). You should be able just Google for the firing order, that is what I did. For the power steering pump, there is a bolt that sits between the pump and the pulley. Loosening and tightening that bolt is what allows you to adjust the pump for the belt. Hope this helps!
Chad Williams great man thanks!
Great video! How much would a reputable shop charge for a rebuild like this on one that's already running, just mostly original and never been rebuilt?
Thanks for watching!! Hopes it helped! I honestly have no clue. It all depends on exactly what they need to do for your specific engine. For example, if they need to bore it over because of ring scaring. If you do get an estimate, I would love to know what they would charge.
Chad Williams it’s hard to say really. Back in the day 25+ years ago I knew a mechanic who came to your house and rebuilt a oil burner for about 1,400 bucks and it would run good for 60-80 thousand miles then after that 20 thousand per rebuild. He is retired now . I suppose a shop would charge a lot more especially if mech. Work was required. That cost 12-15 hundred alone 25 years ago.
@@johnwayne7476 Despite your comment being filled with nostalgic lure of old timey community tradesmen. Your numbers are so way off even for 25 years ago. A basic rebuild with proper machining with replacement wearables, built to "stock" specs is $2500-$3000. It can easily double when you start building power over stock H.P. numbers. But thanks for the story tellin Big John!
@@johnwayne7476 I chuckled at the ‘20 thousand per rebuild’. Anyone asking or paying that much for an oem spec rebuild is mentally ill.
Why no paint on fuel and water pumps? Just curious
Your not going to pull the crank out and replace the main bearings or the rear seal?
I actually did. Should be in the video.
Can you replace the oil pump on a 76 cutlass 442 350 rocket while the engine is still in the car? Or do I have to pull the engine? Thanks in advanced for the answers
You will probably be able to change it in the car, but it won't be fun. If you have a buddy with a lift, that may be your best bet.
What sizes water pump is it short or long
Deep dished pistons
Does your bell housing cover have a hole in it? Mine has a triangular shaped hole in the very middle in the back (transmission side) it definitely is supposed to be there but is your’s open or do you have a seal or something for it?
Hey, I am not 100% sure where/what you are talking about. Are you able to describe it better or post a link of a picture on Google?
Chad Williams there are no pictures on google to describe exactly what I’m taking about but I can email you or send to you somehow the picture that I took of mine
Do u have a link of where u bought your water pump and water neck
I believe I bought the water pump on Rockauto, but I bought the waterneck on Amazon. Link here: amzn.to/3CeTFZ9
audio is difficult to hear clearly until the end ,good instructions
What manual were you using? i have a c-10 that got swapped to a rocket 350
No manual, just lots of Googling and forums. Lots of good guys out there already doing these build, so just learned from them. There might be some manual out there though. Do you have any specific question I might be able to help with?
I built a olds 350 and made 463hp! All for $3200
That thing must be a killer! You got any videos on TH-cam of it? Would love to watch it!
Installed it in a 87 cutlas t top.
@@williamhiggs3718 what did you use
I have a 1986 olds cutless brougham with a 307 engine V-8 will a 350 rocket 5.7 fit right in without changing out parts ?
I would say that 99 percent of things should switch right over. You may have an odd ball thing here or there, but the general swap has been done before
It should be as easy as it gets leave the mounts where they are take one out put another right in and not know the difference from one to the other by the outside
No a sub 350 chevy will I believe trans bolts are different there is an easy way to addapt though I think 2 holes don't line up a rocket uses the big block olds tranny they are not the same block as a 350 chevy it's the same block as a 403
And if you wanna use a high rise intake prepare to install a scoop and hit the hood but you may get lucky some turbo hydomatic tranny's have both sets of bolt holes but I doubt 86 will 84 was the last year of true rockets
Do you remember the specs on the cam you used?
Hey Matthew! Here is the link for the comp cam I got. I really like it! :) www.compperformancegroupstores.com/store/merchant.mvc?Screen=PROD&Store_Code=CC&Product_Code=42-600-5&Category_Code=THMSBC8
What size heads do you have I have the same motor but my heads are stamped with an 8, what should or what do you recommend for change or keep those
7, 7a, 6, 5 heads from a 1972 or earlier will bump up your compression ratio a bit because from 1973 and up Oldsmobile went to a higher CC volume in cylinder heads to lower compression ratios.
Looks like he had two different heads in the video. One was a 7 A and the other was a 6. Something isn't going to run right. The number 8 heads can give you good power, but the best heads are the 5, 6, 7 and 7 A. They are 64CC heads. I would just have them cut for bigger valves.
looks like stock heads with stock components - springs, rocker arms, probably push rods. The Thumper Cam with that lift and duration should have a double spring set up that Comp Cam recommends and sells as a kit. Rev that engine to 6K maybe a hand full of times, might be lucky before bending push rods floating valves or ingest a valve into the bore.
With all due respect, not to insult you but your video title is misleading - what you did was a re-ring not a rebuild. I didn't notice maybe I missed it, if you replaced the oil pump while you had the motor torn down at the very least polished the crank and installed new main bearings.

Can you please help?! I have an olds 350 casting # 557752-3b, it was a swap from a stock 307 from my 1983 olds 98, and everything was switched over, the mechanic told me to order parts as if it is a 1983 307 (intake manifold & carb are from the 307). Problem i'm having is that the starter does not seem to want to start the engine. I'll get one good start then it'll struggle and chug. New battery, altenator, battery wires and all. Which starter would you suggest for this engine? any help is greatly apprecaite! Thanks so much!
Hey Secret Santa, I bought a normal starter from Advance Auto, I think their Carquest model since they have merged. Mine engages and starts everytime. Was the starter shimmed correctly? I would also double check your voltage at the starter to make sure you are seeing the correct voltage, that you see from the battery.
I would also make sure the starter heat shield is installed. These motors were terrible about heat soak in the starters. After the engine gets hot and then you park all that manifold heat gets in the starter and then it's difficult to crank.
After driving my olds 350 for a few months my fan belts snapped and I realized my pulleys were unaligned, I’m almost positive it’s just the power steering pump that’s unaligned, have you had any pulley alignment issues? I don’t have a serial number on my power steering so I can’t look it up, what water pump/PS/alternator setup do you have? Thanks!
Check out this company called Inline Tube. They make reproduction pulleys for all applications of the Cutlass. I got mine there. It was trial and error, I returned a couple until I got it right. I don’t know if I would be much help in telling you exactly which one you would need. :(

Chad Williams I will definitely check them out thank u!

Steven Marchese take your car to a mechanic you have way to many simple problems
I don't recommend long tube headers,,,mine were a nightmare,. But they were gifted.
Did you have to degree the cam
Whats the cost to rebuild one??
Do you know what size the bolts for the oil pump are
I took my engine apart a year ago and can't remember where I put them
Hey, sorry, I don't remember off the top of my head :(
Chad Williams ok thanks
Yea man good video but i was just wondering why didnt you paint water pump fuel pump and intake gold
I like a little contrast in color. :) I wish I would have at least painted the water pump silver, since it did end up rusting lol :)
@@ChadWilliamsFixesAll yea dude if you dont paint them they will rist thats why i painted mine on my 70 S 350 rocket. But ay yiu did a great job man looks real good👍clean af
How you get the crankshaft bolt unloosen
I used my air impact gun. If you don't have an air impact gun, an electric impact gun could work. Good luck!
What I've done in the past if the engine is in the car, is use a breaker bar against the frame rail and then bump the starter.
Or if it's out of the car, put a block of wood between the crankshaft and the block to keep the crank from turning.
Hey,did you use a electronic distributor?
Hey! I used the HEI Oldsmobile Distributor from Summit. Works great!
I'm sure it does all I've ever run is hei distributors I'm thinking about trying an Msd box 6.a.l or whatever it is with an hei distributor and see if it helps
@@glennmanchester1568
An HEI will give you all the spark you need
Adding more just overcomplicates things.
Did you ever finish or did you leave us hanging?
Hey! I did finish the rebuild and I do have a start up video on my channel. Last year, I plasti dipped the whole car so it wouldn’t rust anymore. This year, I plan to throw on some EFI. I will have a video for that too. Keep an eye on my channel, will have much more content. :)
Hey can you do a video for 350 rocket putting it in Timing
Hey, sorry, I can't right now. It may be fairly close to a SBC 350.
Duration of cam @ .050s?
Here is the exact one I have.
www.summitracing.com/parts/CCA-CL42-600-5
The sealer can be applied directly to the hole in block and is less messy.
Did the block go to or even need a machine shop???
Hey! Mine never needed to go to the machine shop, but it wouldn’t have hurt. Still running strong though
What vehicle year and model/trim do you use to find your parts? I recently acquired a 1980 Chevy C10 that has 350 rocket engine and I'm having issues finding parts for it since I'm not too familiar with what vehicles that engine originally came with
That engine cams in a lot of vehicles from 1968 to the 1980 s I think but run the numbers off the block to find out what year the engine was made and that will help considerably but they didn't change a whole lot but it depends on what parts your looking for exactly internal or external external it shouldn't be that hard just match up your old part w the new one to make sure its right
Did u bore the engine?
I personally didn’t, the people I bought it from did a .20 over bore on the motor.
What book did you use for this?
Just a lot of Googling. I also have an old Chilton book.
Did it cover specific years? Looking for 73 omega 350 rocket rebuild I think yours may be the one.
why do you use SAE30 monograde oil...... why not 10w30 high zinc
This is break in oil. Break in oil have high zinc for that reason.
Hi , How can I tell if the engine I have is a true Rocket Engine supposed to be a Olds 1971 Olds Cutless. I trusted him then but heard something he done to another friend of mine, now not sure !!! Can you help me. Thanks 😊
Every Olds v8 from 64 to 87 is a Rocket engine
What are the specs on the comp cam
google
This is not a full engine rebuild but just a rering job with new bearings and gaskets. If it was a full rebuild you would had have the block hot tanked clean oil passages out turn the crank and bore it out and redo the heads. And you should use a cam bearing installer
Maybe you can post your how to video.
Hey bro can you rebuild my engine for me I have a 76 Oldsmobile 98 I want to say I have a 350 rocket in it and if so how much will something like that cost me
Hey! Thanks for watching! I can't really help with the rebuild, sorry, but I really hope my videos can help you turn some wrenches to get your engine complete!
Odd that you have a 6 casting head on one side and a 7a head on the other.
About how long it take u?
You one of those silicone guys who puts that shit everywhere?
Why do you say that? Because I put gasket maker around the expansion plugs, 2 spots on the oil pan, and a little on the intake manifold? I didn't go crazy with anything, just doing it where you are suppose to.
are the olds head bolts tty? can they be reused i heard they are. but most head bolts are not. thanks
tty bolts are usually found in late model engines. Older ones like this are most likely reusable. Always best to double ck though. No need for expensive ones though
