Hi Nicholas, Too bad you lost some of your footage. Oldsmobile engine rebuilds are something that's seldom seen. The engines from Oldsmobile were just so good, they seldom broke down. They really were the mark of excellence. Roland
I enjoyed watching. I was involved in a 1964 Olds 394 ultra high compression 345 HP rebuild from a Super 88 in high school before this engine was made you just rebuilt. I drove a new Olds 98 LS in 1974 with this 455 engine in it.
I've seen, on another engine builders page, that alot of machine shops outright refuse to build engines with flat tappet cams due to the cost of rebuilding them after a tappet fails. Nice to see a shop that knows how to combat this. Top notch outfit you and your dad run.
Those are J heads from 73 and later. Would have been better to use earlier. The pistons he removed were the low compression pistons. I have a 73 block with 70 heads and pistons. Looks stock, just earlier
@@donaldbabineau1063 yeah the first generation had the best heads by far. The heads on the later models were really inefficient so everyone just replaces them with aluminum heads but I like to see people modify the old iron heads just to see what they can do.
I gave my son the 1966 Cutlass f-85 coup deluxe. That we had with our kids growing up. And with all of the updated aftermarket parts with the 455 engine. And when our son was older and he started his family I gave him the car. And he has restored it and he has done all of the body work and the original paint color. And he put disc brakes all the way around, and the engine has the new pistons and aluminum heads and bored out. And has a fuel injection carburetor. And has 700 plus horse power. So I am so glad to see you guys doing an Oldsmobile engine finally.
I did one of these for a boat installed oil restriction dowels in main journals to reduce oil flow to the top end and keep more oil in the pan. Something an old drag racer suggested. Of course that was 35 years ago.
You and Your Great Father Do Some Beautiful Work!.... Yall inspire and touch many people's lives. Thank You For Sharing Your Lives With All Of Us....🙂👍
I was a "Job Shop" Machinist, (not automotive, just creating making stuff off Blue Prints) back in the 70's, followed by 25+ years in Auto Repair. I really enjoyed this video ! Questions: Why steel, not brass freeze plugs? What sealer on the F Plugs? What pistons?(brand, composition )? What type rings? Molly? Thanks.
I just got a 71 Vista Cruiser with a 455. You just made me realize I might need to run lead additive in it. The engine has been out for new bearings, but I have no record of any machine work. Not sure if it's had hardened valve seats installed. Would probably need to pull a head to know for sure, huh?
No need to disassemble anything. Go by the letter(s) on the head outer front corner drivers side and outer rear corner passenger side. The G, Ga, and J heads have hardened seats, to my recollection.
Great video and awesome engine build. I have to ask when did you check the piston to deck clearance? I am guessing you measured the deck height after surfacing block then did the math. Am I correct in this assumption? By the way thank you for this awesome content, please keep it coming. I love it.
Be careful with the curled steel on your seat driver. My friend accidentally shot a piece of metal into a finger joint like a bullet. He was using some kind of punch.
Can confirm that this is very real. Had it happen, fortunately did not get stuck in my hand but it was literally like a bullet. Never would have believed it.
I am about to have a 1970 olds 455 rebuilt. I am undecided on the cam I want to go with. This will be going back into the original Delta 88 it was in. It will have a performance intake and 750 carb. Any recommendations would be appreciated. This vehicle will just be used for pleasure driving and a little stop sign to stop sign fun. Recommended cam? Go back to low compression or go high compression?
My recommendation would be to go with the high compression pistons and a very mild cam. If I remember correctly, we used our Engine Pro Stage 2 Torque cam in this engine. You can check the specs out here: jamsionline.com/oldsmobile-v8-260-350-425-stage-2-448-472-lift-cam-camshaft-lifters-kit-mc1777/ Also might recommend switching over to an EFI system to replace that carb. This customer used a Holley EFI system if I remember correctly.
I would go with something like Engle 22-25-10. 230/236 duration and .512./.523 lift on 110 lsa. Will idle at 600 and enough vacuum for power brakes. 9.5 compression should be good 👍
@@robtdougherty this is the cam I used in my 468 with 9.8:1 compression. Ran 11.80's in a 3750 lbs car with 3.73 gears 2000 rpm stall and shifting at 5200 rpm. 1.62 60 ft. Torque monster.
Absolutely high compression, moderate cam. Oldsmobile motors start producing good tourqe at low RPMs. With good compression ratio and decent airflow, has an exceptionally long powerband, doesn't need to rev much above 5500 RPMs for big peak power.
Olds 455 is a ripper right out of the box. Believe it or not, in the OEM big boys shootout, it was the fastest big block you could get in 1968-72. I don't remember who did it, maybe powernation? They took Chevelles, Cudas, Mustangs, GS and so on. The 455 was consistently the fastest. Faster than even the legendary Hemis. It's a torque monster.
Probably been asked before but why do you air hammer the valve guides in rather than use a press ? Just watched one of your JD head rebuild videos where you broke a couple of guides on installation . Just seems a harsh way of doing it but I guess there is a reason .
There is 2 different ways to remove the pins one way does damage the pistons and the other way you have a fixture that holds the rod and allows you to remove the pin without any damage to the pistons if you are planning to reuse them.
So, when you resize the rods, this makes them slightly shorter. Does the amount you surface the deck correspond to keep the compression and piston "depth" the same?
Very cool! Just wondering, have you ever made an un-fixable mistake while machining a part? If I was a machinist I would constantly worry about messing something up beyond repair.
Mistakes happen too easily. Anyone who claims they don’t make mistakes is a liar. Luckily, most mistakes are repairable, and all mistakes are avoidable when attention is paid. That being said, we have made mistakes that were cheaper to fix w/ a new replacement part as opposed to fixing otherwise. It happens lol!
While not required machining cast iron, I sometimes just like to use some coolant to side in cutting seat counterbore pockets. In this case just coolant out of our flywheel grinder
Regardless, a consideration must be made of whether the material hardness will be retained by the integral exhaust seat by the time it has been ground/cut once, twice, or possibly even a third time. While they may have been hard enough from the factory, excessive material removal will cut through the hardened material leaving only the non hardened cast iron. When we do not know the history of the heads with complete confidence, but see evidence of a previous valve job performed, it is our preference to install hardened seats to be 100% sure they are up to our quality standards.
No balancing required? With a performance cam, and bigger pistons, I thought you guys would've used your new Sunnen balance machine. Also, with all the new customers your videos are bringing in, maybe you should hire a professional video-er (?), while you guys work. Advertising is a good investment.
looks great, that driving tool you use to drive in valve seats is really mushroomed pleas.e dress it up, i got a piece of chisel in me now that i will take to the grave
Whether or not they ever saw leaded fuel is irrelevant. Doesn't change the fact that exhaust seats need to have hard exhaust seat inserts to withstand TODAY's unleaded fuels.
Sorry, that's not true. Too much zinc causes the oil to become acidic and corrosive thereby damaging cam and crank bearings. It's like salt on food - not too little, and not too much.

When you show in detail how you bring those engines back to life. 👍👍👍👍👍
What have you learned along the way? Can you describe how the videos have enriched your knowledge of mechanics?
Yeah, Olds 455 Rocket! Had one in a 72 Delta 88 my folks had bought new. Boat of a car, but make no mistake, that thing would move.
oh yeah
I did one of these for a boat installed oil restriction dowels in main journals to reduce oil flow to the top end and keep more oil in the pan.

Glad you went with the new intake. Looks great!
Great video Oldsmobile power👍🏾
Done an absolutely stunning job.
wow that block cleaned up nice!
Nice job, I don't work on engines but really love the craftsmanship
That engine looks great !!
It looks GREAT:)
WOULD be niice to know the Cam Specs on this, or part #.
Very Cool Man
Gorgeous engine
Cool 😎
455 olds is my favorite engine
Awesome Job Guys ! Next time I am up there I will have to inquire. !

Hey I am from India
And, I really like your videos!
Hey, thanks!
Old school machine work 👍 awesome
It takes years to learn this stuff you don't get good over night
Great job
I stuffed a stock 68 455 in my 72 Skylark.
500 lb ft of fun fun FUN !
Ahh the 455 rocket
I kinda wanna see a vid showing some details on that uni-joint you use when honing. Seems like one hell of a heartache saver
Don't forget hardened seats
I just got a 71 Vista Cruiser with a 455. You just made me realize I might need to run lead additive in it.

I'd love to have you rebuild an engine for me. You do great work.
Great show again. To bad you cover up all the shiny parts inside the engine.
When your machining a block, it's no longer considered a minor rebuild.
Great video and awesome engine build. I have to ask when did you check the piston to deck clearance? I am guessing you measured the deck height after surfacing block then did the math. Am I correct in this assumption? By the way thank you for this awesome content, please keep it coming. I love it.

What kinda power did it end up making?
Red Line Synthetic Oil should work well with Flat-Tappet Camshafts

Lucore Auto did something similar a couple years ago.
I never understood why the 442’s were never in the Nascar races or Indy 500’s. If they had that fastest motor back then.🤷♀️
One in my shed. stock torque about 500 just motor baby
No balancer install tool ? Seeing you hammer the balancer on is the first thing I have seen you guys do that made me scratch my head.
I know I didn't use one on my 455 either, slid right on if I recall.
Did you add oil restricters in the main bearings? 455 are infamous for oil issue's
Hey Jim. Where do you get the one piece gasket from?? Oil pan?
Probably been asked before but why do you air hammer the valve guides in rather than use a press ? Just watched one of your JD head rebuild videos where you broke a couple of guides on installation . Just seems a harsh way of doing it but I guess there is a reason .
What your placement/directions for rings gap before seating into the cylinder.
What was the cost of this rebuild I have A 71 442 455 looking to get the motor cleaned up repainted and ready for the restore.
Any info on the cam, pistons and how much more power it made than stock?
Great work, I'm wondering how the wrist pins are removed for rod refurbishing. Are the pistons ruined?
There is 2 different ways to remove the pins one way does damage the pistons and the other way you have a fixture that holds the rod and allows you to remove the pin without any damage to the pistons if you are planning to reuse them.
So, when you resize the rods, this makes them slightly shorter. Does the amount you surface the deck correspond to keep the compression and piston "depth" the same?
How much was that build what size cam
cool
How much do you charge for a rebuild like this one
whats the price? i have a 455 i want done.
Same
I have one of these in my 64 Cutlass. I am in Nashville TN. Would you be interested in building mine just like this? Willing to ship it.
What’s the average turnaround time for a shop to do this? And average price?
how much does a mild rebuild like this cost ?
Very cool! Just wondering, have you ever made an un-fixable mistake while machining a part? If I was a machinist I would constantly worry about messing something up beyond repair.

What was that you were spraying while cutting new seat counterbores?
While not required machining cast iron, I sometimes just like to use some coolant to side in cutting seat counterbore pockets. In this case just coolant out of our flywheel grinder
Do new valve seats have a chamfer on the bottom outside edge? Thanks!
Yes, either a chamfer or even a radius on some.
What torque did you have on the bolts?
How much would a job like this cost?
Please let us know the cam spec's and if you dyno'd it
How much did that cost
What are your torque specs for your valve cover on your 455 engine block
Any idea what your invoice total was for the work done in the teardown and part two?
Can you send me a pic of the fireing order from distributor to spark plugs please 🙏
What kind of heads were those? C, j?
SPFR M They are J castings. J means junk.
@@davidcollis4758 Mine are J, they're fine.
Job vecancy?
Frost plugs are wrong. Use threaded ones
What do you torque your oil pan down to
7 ft-lb is enough, too much it warps and leaks. spec is 7 ft-lb
He didn't heat the rods up the first time.
those are unleaded heads.

@@JAMSIONLINE The valvetrain is non adjustable as well and you need to get the valve stem height correct or you will have problems.

This video was done about two years ago well before we got the balancing machine.
looks great, that driving tool you use to drive in valve seats is really mushroomed pleas.e dress it up, i got a piece of chisel in me now that i will take to the grave
It has since been dressed ;)
Bon travail mais la sableuse n'est pas bonne pour sablé les Organes et pièces du moteur
He never checked the rods for straightness
Current flat tapper lifter quality is junk.
Olds Blue motors never seen leaded fuel bro .. unleaded fuel came out in 73 brutha ...
Whether or not they ever saw leaded fuel is irrelevant. Doesn't change the fact that exhaust seats need to have hard exhaust seat inserts to withstand TODAY's unleaded fuels.
Joe mondello says not to do it that way
Or even when you use a breaking oil add the bottle of zddp I add more zinc there's never enough zinc
Sorry, that's not true. Too much zinc causes the oil to become acidic and corrosive thereby damaging cam and crank bearings. It's like salt on food - not too little, and not too much.
Hurrying makes for mistakes
No pros here
Yea doing it wrong too
Those are junk fatigued rods
More annoying background music makes this unwatchable.....
Bummer j heads
Please stop wearing the camera, your movements get nauseating at times. Use a tripod please.
It was a one time try for the video because I thought it would be cool 😂. It wasn’t. I don’t do it anymore lol
"mild" rebuild. lol
slowsmobile
I really HATE this "Hey Paint everything now that Is assembled" look.
In general, that 455 is one of the ugliest motors I've seen.
Fun to watch, though.👍👍👍👍👍👏🏻👏🏻👏🏻👏🏻👏🏻
What do you torque your transmission pan down to
