Its all about style buddy and the joy you get from bulding an engine & the first turn of the key. its not wasting money, I bet my old v8 is still increasing in value while your jappa goes down with ever mile you add.
Nice to see actually what happens, unlike most of the time you hand over the goods to be machined and get it back to spec without seein the processes used. Good video
an average price for a machine shop to refurbish a V8 cylinder block is from $300-$500 US. That will normally include a hot tank wash, boring, decking, honing and plug and cam bearing installation. The average replacement cost for purchasing a new or refurbished block is from $500-$750 US on the low end for a stock replacement. High performance is much higher. You can buy a used block, but then you'd also need to run it through the refurbishing process to begin a rebuilt engine build-up.
The 'Deck' surface of the heads are machined in a similar manner to the Block Deck. It's a different machine that is set up specifically for holding cylinder heads and machining them. Head Decking and all other relative machining processes are all shown in our 'Basic Engine Building' DVD. The Machine Shop section of the DVD is pretty cool, it shows all these machines that most people don't get to see in action behind the closed doors of the shop.
Machine shops don't really "make" engines, but I know for a fact that the guys here at Edding's Engine Rebuilding can do the refurbishing machine work for any and all engines ever created...
@Sonicku yes, if you bore out the cylinder, you absolutely have to replace the pistons. There are no replacement piston rings that can 'take up the slack' of the bore. An average bore increase is at least 0.010" (ten thousandths of an inch). Although it sounds like a small increment, it's a large difference in the diameter of the cylinder bore and will require a new larger piston diameter to allow for proper sealing of the bore with, of course, new piston rings as well.
There are two blocks shown in this clip... first one visible during the 'align hone' is a small-block Ford 351. The ones being decked and bored are Small-block Chevy 350's. There are much larger engine blocks made by both Ford and Chevy. The small-block piston diameters range around 3 inches and the big block engines go up to and beyond 4 inches in diameter for each piston. They probably do look pretty large though if you've only seen 4 cylinder engine blocks in the past...
@NORMAN3016 Boring out the cylinder could be used to slightly increase horsepower, but as seen here, the procedure is being used to refurbish the cylinder block for an engine rebuild. The block is bored and then honed and new, slightly larger pistons are installed into the block. This way the engine block has a new life ahead of it after a complete rebuild with new piston rings and engine bearings.
@Demon1987 The entire procedure listed above is usually offered by a complete machine shop and is often referred to as a "block service" or "block overhaul" package. At many places it will include at least a cleaning, inspection, hone and possibly camshaft bearing installation and plug replacement. Other additional services that can be added to the block are de-burring, align hone, bore and hone (with or without deck plate), deck scim and other types of damage repair or welding if needed.
@Boredout454 yes, you're correct. There are plenty of over sized pistons beyond the 0.060" range. However, the stock replacement ranges are limited to .010 .020 .030 .040 and .060 anything larger needs to come from a custom piston manufacture or custom order from one of the OEMs. We even talked to one of our OEM manufacture sponsors a while back and asked why there is no .050 over stock piston... they said "it's just that way". so much for a complete answer.
There are thousands of machine shops across the country that use tried-and-true machines such as the ones used in these clips. The cost and functionality of modern CNC machines are just not suited to everyday automotive engine block boring. Sure, some of them are capable of doing the work, but their strengths are much more suited to custom machining detailed pieces as opposed to boring dozens of hardened steel cylinder walls in a day. However, this shop does have a CNC machine for other jobs.
These are industry standard machines that produces industry standard "smoothness" for stock engine rebuild applications. There are performance finishes that can be achieved as well, but are not needed without the use of special sealing gaskets intended for higher compression performance applications.
All piston based engines are capable of being bored out as long as the maximum bore diameter has not been reached. After performing a bore on all cylinders in a block, the cylinders are honed to the exact diameter required by the new slightly oversized pistons.
@wyckedtracker This is a quick sample from a DVD that is over 3 1/2 hours long... There is footage of the magnaflux process for crack checking on the full length DVD in the machine shop section.
@BoxWrench ...and a correction as pointed out by @brizopolahko... Not ALL aluminum blocks have steel sleeve inserts acting as cylinders. In some exotics, performance engines and other specialty engine designs, cylinder walls can be made of various alloys that require special casting/forging, tooling and finishing procedures. However, the vast majority of aluminum blocks in stock engine designs do stick with steel cylinder sleeves for ease of machining and cost efficiency.
If you listen and watch closely, the dialog says "the machine needs to be set in the approximate centerline..." this is just to get the boring spindle in the ballpark of the first cylinder. The next line states that " this particular machine with then center itself in the bore..." You can even watch the spindle shift to the left as the machine does a perfect self alignment to the true centerline of the bore. It looks like an older machine, but it's a fully automated and highly accurate one.
@DevinWhiteman easiest thing to do if you want to experiment with building a V8 engine from scratch is to first get ahold of one. You could probably find a junk engine (get a full long-block with the heads included) pretty easily and then get it home and put it on an engine stand. After that you pull it apart and start the visual inspection. If you want to follow along from the disassembly, to the machining required to the pre-assembly and then final assembly and sealing... you can get our DVD
@buckracer thanks alot for the info. like others im so tite on chash its not even funny but ill scoop up some info to figure out how much i should start saveing up... im defenetly planing on keeping my old truck for a very long time and i would be so happy knowing the engine is as perfect as it can be.
Actually, boring with a torque plate is completely unnecessary when performing a stock engine rebuild. The clip shown here is from our 'Basic Engine Building' DVD. It shows the complete processes needed for a proper stock re-build. The use of a torque plate and the closer tolerances it achieves are only needed when boring a high performance block application. No adverse effects occur when boring a stock spec block without a torque plate... ask any reputable engine shop that does high volume
you should hone with a torque plate especially modern thin wall cast engines and high performance ones . Even on a bone stock 350 chevy honing with a torque plate will make the engine last much longer. many shops dealing with high performance and modern thin wall blocks will use a torque plate and (Hot hone) means pump hot water through the block while honing it.
@viper666666 That would likely be a call for the machine shop to make. It would probably depend on the age and accuracy of the the boring machine itself. The one pictured in this video is an older "trustworthy" machine that does, V8's all day... other machines may be more accurate for aluminum blocks, or you could be right about a torque plate being needed regardless for an aluminum bore. Not a whole lot of stock aluminum blocks out there though. Most imports have steel cylinder sleeves
I helped my shop teacher do something similiar, we clamped sand paper really tight to a table and put oil on there and then drug it across the sandpaper.
...actually a quick clarification. All Aluminum blocks have steel cylinder sleeves. Aluminum is too soft of a metal. When the boring job is performed on an aluminum block, the steel sleeves are bored out out, or the block is split, and the sleeves are removed and replaced with smaller diameter if it's desired to return the sleeves to stock diameter.
@LittleMan00707 you can call any machine shop and ask them the pricing for a block rebuild for your specific engine type. You would be better off to have the block honed, and pistons cleaned and inspected if you're going to re-ring and install new bearings.
@LittleMan00707 We're not a machine shop, we produce engine building videos and re-sell transmission rebuilding DVDs and other automotive videos. We used Edding's Engine Rebuilding in San Fernando California. If you live in So-Cal, you can contact them for a quote.
@1PARADOXXX If you count the cylinders visible in this video, you'll see mostly V8's shown here. If you see 4 cylinders on one side of a V8, there's gonna be a matching 4 on the other side to make a V8...
@brizopolahko yes, you are correct... should have said "most" engines instead of "all" to include the rare exceptions. correction listed along-side original post below...
@Demon1987 not only to you, but to everyone- this is not hard. if you are into cars, you probably know someone who has used a machinist. ask them who their machinist was and call them up for details on their services. or if you have no friends, go to the local drag strip and find a car thats running low times and is something close to your engine. walk up and ask them who their machinist is. GOOD machinists will do ANY perfect procedures, decking, honing, cleaning. or try the yellow pages.
@pavel4 Call a machine shop to get an actual quote, sometimes the do package deals if you're going to to a complete block overhaul with cleaning, boring, honing and bearing installation all in one. For just a bore of a V8 block the average is about $75-$125 US. You'd still have to get the hone done however, and that's another average of $100. If you do a package deal, you'll get a better deal. Of course, V6 or line 4 engines are going to be less expensive than an 8 cylinder block.
If you cut the bore that means you wont be able to use the original factory pistons right? because the bore is now bigger? or is their like speacial piston rings that would be able to close the Gap? or would one need new bigger pistons?
@BoxWrench so to do this i should take my hole block then? would they only do the block or heads too? or would it depend on the shop? is it worth it or too expensive?
This video has an Align Hone machine, a Deck Surfacing Machine and a Block Boring Machine, each of which could cost up to $100,000 US dollars or more new from a manufacturer. There are used ones available but it doesn't make sense to purchase any of them unless it's your line of business and you can earn back your investment...or you're incredibly wealthy
do you know if there are any shops like this in seattle washington i have a chevy 350 engine and i want the block and pistons to be done correctly everything else im doing on my own(a learning experience if you're asking)
Just call a local machine shop and see what they charge. Ask if they have package deals for a complete block job including; jet wash, decking, honing and cam bearing install (cylinder boring if you need it).
There aren't 'protected secrets' in our DVD titled "Basic Engine Building". That's the point of the video, getting a correct base foundation of knowledge out to people that would otherwise sit on the fence about attempting a rebuild. Fact is, if you have a machine shop or provide performance engine building services, we're helping you greatly by getting more people involved who would otherwise just junk their old classic and drive a Honda. Why limit your own customer base and market?
core shift is when during the casting process the cores shift slightly out of place, usually easiest to see by the cam bearing having more "meat" on one side...i.e. "shifted"
i want to start a project building a V8 from scratch, I really dont have any mechanic experience or any thing. Is it possible for the average guy to try to do this in their garage, and if so does anybody know any good guides, and where to start on a project like this for a beginner?
Yup, that machine is a bit creepy to be around, but it's been doing a fine job at skimming decks for over 40 years. Why retire such a classic and functional machine, it does one job, very well. It was a bit creepy shooting the scene though, notice the zoom work from the camera...I didn't want to be too close to the flying blades of fury : )
I've asked a number of technicians over the years about why they skip the .050" increment in stock piston sizes... The only answer I ever get is that "it's just always been that way". I'm hoping for a better answer myself one of these days...
@dtiydr negative. there's no play in the honing stone, it has even pressure all the way around the hole, even if there was a little bit of play in the up and down movement, which i sincerely doubt, the pressure of the honing stone/circular movement would grind it into a perfect circle. there is just too little play, engineered that way because the goal is to get a perfect circle, not to take peoples money and say job well done :P
Please respond to this video with your 'way more awesome' video about machine shop procedures. We expect it to have multiple narrators, background music, a graphical title card intro and be part of a larger multi-hour instructional DVD with computer animations and expert instructions that you also sell direct to the public internationally. Otherwise, your comment about our videos being crap might be a bit off the mark...
Are you serious? Where am I going to buy a huge machine like this on ebay? Just shipping alone would kill me. I think I'll stick to using a drill bit steel brush and some steel wool, and let the axle and cylinders wear everything into the right shape.
Why did your post have to be a year old? I have a Ford F-150 302 V8 with blowback. I don't have the time, tools or money to fix it. If you're still around I think it'd be a good project.
The guy in this video is an experienced machinist and would probably tell you it's safe to wear a bracelet... Some purists would say you can't have long hair or any type of jewelry at all when performing any type of work. Others bend the rules... I suppose if you own the company or your boss doesn't mind, anything goes...
I had my 302 chevy 1969 z-28 done for $125 That included magnaflux. honing the cylinders, cutting the crank 60ths (crank and block) installing the cam bearings, and hot tank everything. And I paid for it all working for McDonalds. Shit but modern times suck.
I use flat-tappet solid lifter cams, and do not have lobe wear problems. There's an old trick in engine block prep that the old machinists use that prevents lobe wear from a flat-tappet cams' lifters. Next time you have a block prepped sit down and talk to the machinist about your concerns, if he knows the trick he'll set it up in the machining process, if he dosen't know tell him to find out.
Quebexicano. The reason people will spend the money for it is because QUALITY matters. Lambo or not, if im going to do an engine, its going to be perfict, not half assed. Just for my ford 302, I put easy 8 grand into it. It took me years for that money but it going to be a fantastic engine because of it. To be honest with you, 128,000 isnt much at all. I wish I had a rig with that many miles.
Its all about style buddy and the joy you get from bulding an engine & the first turn of the key. its not wasting money, I bet my old v8 is still increasing in value while your jappa goes down with ever mile you add.
thats is the most beautifuless rebore machine my eyes have ever seen in my whole life!

Wouldnt the weight of the honingstone make the holes to be slightly more ground on the bottom then on the top?
nice machines. i wish we had something like that at our shop.....
@LittleMan00707 you can call any machine shop and ask them the pricing for a block rebuild for your specific engine type.

How do you finish the cylinder head after machining to get it smooth (not the bores, but the face that is in contact with the gasket) ?
whats the material most commonly used for the engine blocks? and are they the same material as the pistons?
you only need a torque plate when aproaching 800hp or more. also depending on cylinder wall thickness.
@BoxWrench so to do this i should take my hole block then? would they only do the block or heads too? or would it depend on the shop? is it worth it or too expensive?

That looks pretty precise. So how much will that affect to the age of the engine and the power output?
None will likely last longer. Maybe a slight power gain due to bigger bore
do you need a new machinist? I LOVE that kind of work!

good one!!
They do have a CNC machine as well.

The only answer I ever get is that "it's just always been that way".
I'm hoping for a better answer myself one of these days...
your comment is perfect...
hi mate do yon know who much that machine cost ... thnaks
this was impressive like 20 years ago...
Still is impressive today
how much does an average 0.60 boring cost for a sbc(small block Chevy)
Where is this machine shop?
excellent !!!!!
can you show magnaflux testing
Top bad this full video (DVD) is not available...
@whyximxhott dont diss the 4 bangers, i got a 3 banger lol, it hauls ass.
Isn't that a tape-controlled boring machine?
thank you .

@motabikeboy I was going to make the same comment too! I changed my mind because I thought it might be too boring.
I use flat-tappet solid lifter cams, and do not have lobe wear problems. There's an old trick in engine block prep that the old machinists use that prevents lobe wear from a flat-tappet cams' lifters. Next time you have a block prepped sit down and talk to the machinist about your concerns, if he knows the trick he'll set it up in the machining process, if he dosen't know tell him to find out.
why honnning and boring are in different machines?

The reason people will spend the money for it is because QUALITY matters. Lambo or not, if im going to do an engine, its going to be perfict, not half assed. Just for my ford 302, I put easy 8 grand into it. It took me years for that money but it going to be a fantastic engine because of it.
To be honest with you, 128,000 isnt much at all. I wish I had a rig with that many miles.
@sovereign126 Interesting, thanks for the info!
