3 years later this is still the best build block build video on the whole internet. I watched every second of every video.. Man I was so scared to tear into my 454 big block in my 1970 Chevelle but man you gave me confidence to get to it.. I might use everything you used unless you have feedback on what you would’ve done differently? Fantastic videos & fantastic reason for doing the videos. I am glad you got to do it with your dad!
That's so nice of you! You got this!
Nope I wouldn't change a thing. I still love everything about mine! Thanks for watching!
Warning! This series will suck you in and you will binge watch it! I can not compliment you enough on the quality of the videos. Your commentary is clear and concise and easy to follow and understand. I was just curious about what is involved with building a 454. Now I’m searching for a block. Thank you.
That's so awesome to read! Thank you so much for watching!
Thank you for this. Honestly think i learned more in this series than i expected when i started. Well done.
Glad it was helpful!
I agree also.learned more than I thought I would've
@@2carpros awesome videos just had a question when you adjusted total timing was your timing advanced hooked up or not? and wat was the initial timing set to, some people say 4 or 8 or even 12 at idle with vaccum hose disconnected. Thanks
This series is so underrated. Really appreciate every detail in each part.Cant wait to start my own build.
Hey thanks so much for watching! I want everyone to build their own engines so the muscle car era can happen again!
I have several big blocks I have wanted to rebuild. Thanks for your series, I now feel like I can do it.
Nice! Yep, you got this! Thanks for watching!
So after I pulled my 472 out I’m now working on building a 454 just watched the entire series and I’m impressed! Can’t wait to get started!
NICE! Thanks for watching!
@@2carpros thank you for making this ! Saves some money a little lol
i really appreciate this series brother, thank you! The details and well explained methods have taught me how to proceed with my gen IV 454. It's cool that you've added this content to RUclips. There's no greater reason than to honor your Grandfather and your Dad with this legacy knowledge. Thanks man.
Hey thanks so much for your comment and for watching!
This video compilation has made my rockie 454 build so much easier. I’ve read through the Haynes manual, which is good for learning, but hard to follow with minimal experience. These videos are detailed and easy to follow.
“That’s the fun of these cars, they require work”.
So true.
That’s me finished all 3 engine rebuild playlists.
Enjoyed them a lot, learned a lot. Well done.
Always fun to tinker!
Thanks so much for watching them all!
This series was amazing. I'm trying to replace a 350 5.7L (small block, for those who don't know) and I watched your entire series just to get my head around what needs to be done. So helpful! Thanks.
Yeah this is super similar to a SBC. Thanks for watching!
Ryan Ryan, can't thank you enough bro, I have watch the whole series 3 times 🥴, and starting my build 5 months ago, and I just finished my 1st ever bb chevy build
Once again cheers man 👍🏾🙂👍🏾
Awesome! So cool to read that! Thanks for watching!
3-25-2023 Very good job. And Mr. 454 sounds good.
Perfect! I agree about Powerblock - I have watched it forever and I enjoy it but I learned more in this series and the 5.3 than I did in all those years of watching those TV shows. I am sure your grandfather would be extremely proud!
Hey Gary, thanks so much for saying that and for watching!
Hands down the best video series in my opinion.
Purchased a 1969 impala 2 door coupe with a 327cu and 2 speed power glide last year. I want to put in a 454 big block and a 4 speed automatic. Thanks to your videos i will have the confidence to rebuild that 454 myself. Thank you for taking your time in producing these videos. E. Vega
Nice! Thanks for watching!
Dude, finished watching your series…very well done. Keep doing it 👍
Thanks a ton!
Thanks for all the knowledge provided for free. Great help for completing my 68 Camaro w/ Gen IV 454 engine.
Great to hear! Thanks for watching!
@@2carpros hey Ryan, I have two more questions for you. Which radiator hoses did you use, do you have p/ns for me? And the spark wire separators look really neat. I'd appreciate a p/n for those. Thanks, Steve
Hey man I really appreciate your content. You have helped me out so much with my Big Block!! I can sit for hours and watch your Videos, I've never seen engine building broken down in such great detail. Thank you Brother.
Awesome, thank you for watching!
No words. Just awesomeness. Pure fire right here. Thanks for doing this build series!
More to come! Thanks for watching Travis!
Can you explain the "35 degrees" on the timing light as it relates to the 0 degree mark on the timing tab? What are you setting to 35 degrees advance if the harmonic balancer line is at 0? My stock application calls for timing to be set at 4 degrees BDC...does that mean I need 39 degrees? I'm confused...
The best series on youtube. I am building my bigblock too. Thank you
Nice! Let me know how it goes! Thanks for watching Mike!
Great series! I'm getting ready to rebuild a '77 454. Perfect time to find this.
Awesome! This is perfect for you then!
This has been an awesome series. Really appreciate all of the detail.
Just starting to tear down my 454 to rebuild as a retirement project. So good to have such information from start to finish. Thank you for doing this.
So glad you found it helpful! Thanks so much for watching Phil and good luck on your build!
Awesome series! I have been searching RUclips for information on actual engine building, and you did the best job here of showing the process for someone who never did it before. I actually feel like I could tackle it now, before a lot of it was a mystery. Thanks so much for this content. :)
Awesome. Now that it's complete let's see a complete disassembly of the same engine in one video. Can't wait to see that cheers haha
lol AND kek
@@earnestbunbury2103 work work
Why would I take it apart though? Thanks for watching!
@@2carpros because it would make interesting content bro.
@@2carpros you should do a Chevy afm engine without deleting it
Huge fan of you, Ryan. Your work is absolutely appreciated
I appreciate that! Thanks for watching June!
Hats off. Absolutely crazy awesome video series. Always been a SBC guy, just picked up a Gen IV, had all kinds of questions. Thank you!
Awesome! Thanks for watching!
Very informative to put towards what i got to do to my 88 chevy 454 also😜
Awesome job Ryan I learned a lot
Thanks Ryan for the awesome videos and knowledge on the 454.
You bet! Thanks for watching!
Awesome guy
Come from a great family
Thank you for your videos
Im still confused between LS or big block to put on my project will watch your LS build to take my decision
Your videos are so cool it worth the time
I wish I had a friend like you
Huge regards.
Your follower from Middle East RAHEEM 🤙🏼
Thanks so much for watching and your kind words! Both are great choices, that's what makes it so hard to choose.
Very informative so that i can work on my 88 chevy 454 also to find low compression due to new timming chain kit i put in😜
Powerblock TV was AWESOME!!!
LOVED Powerblock TV. Can't tell you how many mornings I got up early to watch it. Thanks for watching!
@@2carpros So have I. Like getting up early to watch Saturday morning cartoons. 🤣 I’ve recently came across your channel. in the past 2 days. I’ve watched every part of this build!!! Thank you for being informative and detailed. My wife has a ‘70 chevelle with a 454 motor in it, very good looking car. It’s not a true SS but that’s okay. There’s a lot of bugs to address and the motor is one. She’s thinking of buying a new motor for $13k. I haven’t priced checked all the parts you’ve used in the rebuild but I’m leaning towards rebuilding it the way you did yours. The motor is out of a truck as well. I forget the code and year tho. Sorry, I’m writing a novel but I’m trying to be brief but it’s hard. 🤣 Would it be cheaper to buy the $13k motor or rebuild it like this?
Thanks so much for your series I have mine tore down. I cant wait to start building it. With the help Of your series I have the full Confidence that I can totally do it. First I I'm learning sheet metal work and welding.
Big blocks are the best!
They sure are! Thanks for watching Jared!
Nice series, as a long time BBC builder, user, tuner and getting long in the tooth, im sure your father/grandfather would be proud, I know I would....
One misconception is that 35 degree timing thing, a low of lower compression ( under 11 to 1) open chamber BBC combustion chamber functionality isn't on par with newer fast burn LS/LT style heads ect..
I've literally seen best power on 41-42 degrees with similar castings to what you just used especially in the 10 to 1 and under range...to accomplish this without electronics ( folks don't be scared to spend a few more dollars for a MSD programmable ignition box, your already used to buying the 6AL) buy using custom degree limiting bushings...
So in his example he set his timing at 9 degrees idle and it wasn't 35 total timing...so he moved it up till it was....which increased the initial...the bushing in the counter weights limit the amount of centrifugal advance and the springs control the rate..
With larger cams, big ports and low compression what you can do is run more initial and limit the total with bushings and the spring sets your rate....( how fast timing comes in vs rpm, in his example it was all in by 3500rpm)...
They can be super finicky on timing both for idle and cruise quality along with peak power and torque...often surprisingly on the older designs you can see big gains as long as your hot octane limited ( aka you don't have knock) on up there in timing...just me but most of the ones I build performed best around 37-38 degrees beyond that its a law of diminishing returns...just my 2 cents....
Having optimum timing will make chasing those carb settings he spoke of MUCH easier...and don't let anyone tell you that with enough work ( surprised he didn't go over power valve with the low of vacuum) and knowledge you can literally get it to idle, cruise and WOT with a wideband near EFI precision.....
I use a home converted to sequential MPI street ram intake with a F1A-94 procharger thru a 4l80e OD lockup trans for many years but sometimes I miss the carb tinkering, drilling ect...it can be done the carb was forgiving and doesn't get as much respect as it deserves
Actually on re-read, way to much info and preachy sounding sorry everyone...
I had built an LS for a 69 Camaro and was going to swap mine, then thought how about I maximize the old Dinosaur...aka high velocity small oval ports with a street ram and sequential MPI using a super efficient centri with no intercooler and 4l80e with 3.00 gears and I can cruise at 74mph in the mid 20mpg....
It just pleased me to see someone like you remember these things can be good engines and even modernized to be durable and effective...this 52 year old block has held 1200hp 500 hits....STOCK block with studs
Thanks for all your hard work !! 🙂
My pleasure!
Awesome video series!!! A carb video would be awesome to see. That's the point I'm at right now.
Hey thanks so much for watching Scott! We will do that in the future. I think I need to change power valves and take some jet out.
@@2carpros I'm playing with jetting on my carb and going down 2 sizes and see what that does. But that would be abgreat video series as well. You done a really good job on the 454 build series.
I watch this before I go to sleep. It’s like a cool bed time story. I did rebuild mine, I still seen temp spiking when ac on. I called the dealership and they said I should have an auxiliary fan up front from factory. That’s what what I was missing
That is cool to read! Thanks for watching!
I’d love to see a collab between you and Uncle Tony’s Garage!
Same! Thanks for watching!
top shelf job thanks for all of it
Thanks for watching!
This series has been a life saver for me, I bought an old 454 and this really breaks everything down nice and easy for a beginner like me. Thank you for making this series!! Did you change out the fuel rail? Looks different than in the other videos.
That's awesome! Let me know how it goes! Yes I changed it out because it leaked like crazy. But I'm going to change it again in the next couple months. Thanks for watching!
Congrats bro thanks for the awesome video series
Thank you so much for watching Art!
Love your 68 camaro, especially the color. My first car was a 68 camaro 350 so in Lemans blue
Thank you!
This was a good video series My first car was a 1967 chevelle with a 454 and 456 rear end gears. It would fly
Awesome build. This has really inspired me.
Awesome! Thanks for watching!
What an incredible build series 👏 🙌 I have to ask and I hope you can answer. What is the entire value of the build? Parts, labor, machining, hardware etc...?
Very cool video series, i watched each one. Ill be putting a 454 in a 77 caprice classic sport coupe, w/ holley sniper efi. Thanks for the motivation and detailed 'how to' series. Peace!
That sounds awesome! Thanks for watching!
Once you started screaming while timing it, I lost it 😆. Even funnier once you were done you had the calm collected voice again 😂
I was so excited! That doesn't happen much. Thanks for watching Jason!
WOW!!! Just finished the final video. Thank you so much!! You actually just started something my 7 year old son will remember me building a bbc(becuase of your video's)and one day I'll teach him and so on. All becuase of you man. Thank you so much!!!
Wow that is so cool to read! Thank you so much for watching!!!
I don't know why but I laughed when you started yelling over your motor explaining what you was doing lol
Thanks a lot for everything
Thanks for watching Rufus!
So being that you blocked off the vacuum canister did you put a looser spring on the weights to bring in complete vacuum
great series brother. i learned a lot thanks for sharing your build
Glad you enjoyed it! Thanks for watching!
You have no idea how grateful i am, could you please do a video about the cost and time and things we have to consider building an old amircan engines?
Thanks for watching! Probably not going to do a whole video on the cost and time break down because its varies so much.
Great video
Thanks!
Thank you much!
u did a great job man, if u please go for overdrive trans. mechanical valve if possible.. ur method is professional easy and deep .. give us more fun.. tons of power and old school tunings..
Thank you so much for watching!
what kind of exhaust system are you running? sounds great !!
Why 35° advanced timing? You mentioned the grade of fuel affecting that ideal setting. Can you elaborate please?
Thank you for this!
No worries!
Awesome!! Question: I want to change pistons for less compression in my big block. It has 25 quarter mile runs. If cylinders look clean no scratches can I get away with just a hone? Great series bro
Yeah I'd run it. Thanks for watching!
What trans dip stick tube did you end up using? I'm having a hard time finding one for a 454 with a 4l80e to fit.
Hello watched the series a few times and moved onto the LS rebuild, In that series you mentioned "problems" with getting the the big block to fit into the camaro.Do you mind revisiting this series and let me/us know what issues you ran into any how you over came them.
Sure Neil, I can go into that now. So with the gen 1 Camaro, there are two parts that make it possible. GM originally designed the car for a straight six or a small block Chevy. Then later on in the life of the car decided to stuff a big block in it. The first part is the heater core box, you need the "big block" box. The next and this one threw me for a loop for months. The big block and small block have different engine stands. Not motor mounts but the things the motor mounts bolt to. The big blocks are tiled toward the passenger's side and a little forward to it can fit. I assumed they were the same they aren't. That was the final piece that lets the big block fit in the Camaro. Thanks for watching!
@2CarPros Thank you for the reply. much appreciated. also how about the heads vs cam shaft question. and after a year or two how does the car run did you ever get it on a dyno ??
Neil
Oh I have also heard its best to adjust the idle mixture screws with the air cleaner on.
Yeah but it won't film well and it wouldn't make a very big difference. Thanks for watching!
I rebuilt my 454 by watching your video but I’m having trouble finding the right headers for my car I have a 1977 Chevy impala, can you recommend some headers that work
Nice work! I'm happy to hear that!
I just looked around for awhile and didn't make any headway. I'd call doug thorley headers and tell them what you are doing and they might be able to point you in the right direction. Sometimes they might have something that will work with a little modification. Baring that, you'd be looking into making yours custom or having and exhaust shop do it for you. Thanks for watching!
What horse power were you able to achieve with the 454 rebuild? Also, where can i find a parts list for you 454 build? Thank you for any info.
I did put it on the dyno in the car, we didn’t maker power though, just to tune it. It made 425 at tire but again we weren’t there to make power. This is my personal car and I didn’t want to beat on it. Thanks for watching!
Galling on the oil filter thread when you were showing how to clean up the gasket landing area ...... 11:30 in to video.
I just changed the oil again on my car and the threads are totally fine. Thanks for watching!
This was a great series I watched the 5.3 as well will you ever get around to doing a oldsmobile v8 series there's absolutely no videos on RUclips showing a true step by step bolt for bolt it will definitely be a 1st
Thanks so much for watching both series! I'm sure we will get to it at some point! Engines are always coming my way. Thanks for watching!
Where did you find those valve covers. Looks so clean.
Thank you! Right from Summit Racing! Thanks for watching!
What if you don’t have an adjustable timing light ?
Why not a 5 power valve ? Instead of 8.5 ? With 10 hg mercury? Is it not = double the vacuum ? Nice car and engine combo !
Time for torque, change jets for horsepower
Great Videos! What city and state are you located? Have a big block that’s been sitting and now needs valve guides because of smoke upon starting. Thanks.
Now, it's time to do a Gen 5, most of it's the same, but it's TBI
Haha maybe someday! If I did a Gen 5 it would not be TBI, I'd swap it out for EFI. Thanks for watching!
Pretty cool 454 series 😎 What was the cost on that build?
Thanks for watching! I would guess right around 5k or so. I'm not really sure I didn't keep track.
@@2carpros Absolutely LOVED the series. I just finished rebuilding a 454 in my boat. No training or experience (or professional help...), but I did it! The $5K estimate looks WAY off to me. The heads are $1200 each, then add intake manifold, carb, cam, timing gear set, distributor, pistons, fuel pump, machine shop fees, water pump, lots of parts from Summit Racing, etc. Even if the old engine was free I'm guessing $10K+ cost.
36 is the “sweet spot” on big block n small block chevy
Would you ever consider doing a build series on a turbo 400 transmission or a 700r4?
Hey there! Great question! I would definitely consider it but, engines are just so darn fun to build I can't tear myself away. Thanks for watching!
I hate messing with Hollys. All I needed for my q-jet was a vacuum gauge.
Ah it's not too bad. I want to do a whole video on it. Thanks for watching!
Do you keep the distributor vacuum plugged all the time? What is it's roll in relation to timing?
You can use it as an advance curve but it isn’t typically used in this application. Thanks for watching.
you forgot to mention what your fuel pressure was at when you were adjusting the mixture screws
It's like 8 psi, doesn't need much. Thanks for watching!
Followed your videos to the tee. Started the motor and I have smoke out of the breathers. Any ideas? Am I totally screwed with blowby or could it go away with a little bit of driving.
Okay so a new engine might generate a little bit of smoke and will go away after it breaks in a bit. But if it is larger plumes of smoke then something is wrong. A few things come to mind in descending order of commonality. First you might have put one or more piston rings on upside down or not clocked correctly. Second the machine shop could have machined the holes too big and you have too much clearance. The last thing that comes to mind is if the machine work doesn't have the cylinder bore as a perfect circle. If you like you can send me a video either on Instagram @ryansgarage408 or you can email me ryan@2carpros.com and I can take a look at how much smoke you are having out of the breather. Thank you so much for watching!
@@2carpros will do. Thanks a lot for your help.
Lets go duuuude!!!
@ 11:17 it looks like the Starter Drive is only engaging about 1/3 of the flex plate ring gear.
Nah the bendix kicks out pretty far. Thanks for watching!
you certainly know how to change oil.... I have seen oil plugs put on way too tight, even with an impact at times..... ludicrous
Yeah a lot of people over tighten it. Thanks for watching!
I have a 84 Monte Carlo ss. I was curious what your thoughts are regarding putting a 454 in the Monte?
Why not? It would be sweet! The LS swap is the obvious "go to" so I think a 454 would be unique and sound rad! Thanks for watching!
Hey quick question. When adjusting your fuel idle mixture, if you move one screw a certain amount, don't you have to do the remaining 3 the exact amount such as 1/2 turn out for all 4 screws? This is what I have always heard as well as what Holley recommends. From your video, it seems like you randomly turned each screw to all different adjustments.
Hey Mark, a lot of the footage is edited down to make it interesting. You really don't want to watch me adjust idle fuel mixture for 20 minutes. It is honestly more of an art than a science and I still adjust it to this day based on large weather changes. Thanks for watching!
@@2carpros I actually wouldn't mind watching the unedited version especially if I was learning how, but yes for entertainment purposes and to get the main idea, the edited versions are great.
Hey man, how did you know that 35 was spot for timing? Is there a manual that lists timing settings? Thanks in advance.
I'm sure there is but I just know from building engines you don't see any performance increase past 35 degrees. Thanks for watching!
i know the 454 had 250hp stock With this build with your cam, rockers, intake, and carb. what do you think your makign as far as power?
We are going to dyno the Camaro at some point. So we can guess from that. Thanks for watching!
My 454 doesn’t have any timing marks. How can I properly do the timing? It has a cam but I don’t know the specs of the cam and I think I need timing adjustments because my 454 stutters /bogs when I floor it and can only ease into the gas pedal to bring it up to speed. Thanks!
It has to have timing marks. Clean the damper off and take a closer look. They maybe super faint. That's why I colored ours in white. Thanks for watching Marco!
@@2carpros thank you. I cleaned it up and found it was the metal tab with pointer but need to see if the balancer has marks now. But I’ll have to find tdc and see if the distributor rotor is pointing at the number 1 spark plug? Then make the mark at 0 and do the timing form there? The 454 has a cam with I don’t know the specs. Do you usually retard or advance when there’s a cam? Or just have to drive it and see where the power band is? Thanks !
Also what part of CA are you in?? I am hoping to pick up a 68 camaro soon! It would be cool to meet up!
I plan on doing a cars and coffee meet up in So Cal. I will post about it on the community tab. Cheers!
@@2carpros Awesome, I am up in Bakersfield if you're ever up here!
You forgot to mention when you overturn the oil filter it break the o-ring
How to adjust the timing with the regular timing gun.
Set the timing light to desired timing and advance or retard the distributor until the flash is at 0 while the engine is at 3k rpm or so. That's the easiest if you ask me. Thanks for watching!
@@2carpros thanks I will buy a harbor freight gun basic one, because my it’s too old and didn’t have any knob to adjust nothing. It’s fixed.
@@2carpros what about the vacuum on or off?
Never put an modern LS into a muscle car. Old school for these monsters is the way to go.
I definitely see why people LS swap the older cars but man do I have a soft spot for these old brutes. Thanks for watching!
What would be the max horsepower that you can get out of a 5.7 350
I mean I have seen 350's making 500-550 horsepower. Really depends how much money you want to put into it and how high your want the compression. Also how big of camshaft and lifter ratio you run. It is usually easier to just build a big block if you want big power. Or a LS we just did a whole 5.3L LS build where we made 500hp NA. Those videos are here on the channel as well. Thanks for watching!
How much hp is it making or do you think it’s making ?
I would estimate right at 550 or so. Thanks for watching!
How much hp u making?
Am I the only one that thought of back to the future when he was screaming?
I love that movie! My first car was actually a DeLorean DMC-12. Thanks for watching!
I'm building a 90' SS 454 now and there's so many options. Any idea what kind of horsepower you ended up with?
Very cool! I have seen a very similar build to this one on the dyno make about 550. Thanks for watching!
A word of advice: when explaining things while engine is running, embrace voice over.
I like the engine sounds. Next time I'll do subtitles though. Thanks for watching!
