Lol fun fact, I said oh my gosh a split second before you when that piece dropped lol. Great minds think alike 😂. And thank you for the information BTW! I'm researching this for a stockish/mild built 400. Not a fan of the 1.72" intake valves stock, planning on different heads.
I just found your channel and I’m glad I did. Your shop is awesome and very well equipped, and the most important thing in the shop is the dog. You have exactly what I am in the process of building, a fully equipped shop. I want to be able to handle anything that comes through the door, that is my goal. Now add the puppy into it and it doesn’t get any better than that. Great video and give that little guy a belly rub from me!! Eddie wheels 😬🧑🏻🦽👍 From NJ.
I am suspicious that isn't the first time that level has been in the floor! lol Glad your shop supervisor is feeling better! Old Baily feeling rough after a head over heels trip down the stairs the other day. Poor old feller.
Well, it is the first time it exploded like that lol. I am very aware of old puppies and stairs as I have had many old furry friends and always damn stairs everywhere. They try so hard and it doesn't always work out for them. I hope he feels better soon. I watched my last old puppy take a big spill down a long flight once not too many years ago. I still feel bad about it to this day. He seemed to shake it off as if he meant it lol. But I know.
It's kinda fun lol. I have spent quite a few years on far more updated seat and guide machines with floating heads and live pilots instead of floating tables/fixtures that it took some time to readjust to this oldie. I learned the art of valve jobs on a very similar machine as mine, but was spoiled with modern Serdi machines. This machine does have a very nice geared head on it though. About the most stout pillar drill I have worked with.
So Ive ran them here in Extremely HOT Texas with and without drilling them with zero issues? The new dart 400 block also dont have them and its Siamese cylinder's too? Thats on iron heads. Looks like the aluminum heads would work better anyway at getting rid of the heat?
I've wondered why the top row is necessary. The bottom makes sense since the bores are siamesed and air can definitely get trapped under there as the water jacket is filled. But wouldn't the top side fill normally to the top of the block deck just like any other sbc without issue?
Great to see Sully back in the water, sad to see him riding in the canoe instead of swimming along side. Do those holes in the heads communicate with matching holes into the water jacket of the block?
yup, they line up with the holes in the block. Only 400's have them and most the cheap aftermarket heads require them to be drilled out for use on them. Lots of comments across RUclips on similar content of guys saying they never drilled 'em and had no issues but why take a chance. All the big power making and stock car engine builders I personally know would never suggest running without them. I trust and value their experience so I follow suit.
Beautiful dog! Hey how are you anchoring the head down at an angle like that? I am trying to figure out some new clamping methods for my S&G machine. could you show the bottom piece?
My dog loves water but he won't go near a hose, sprinkler or any form of manhandled water source lol. We got him a kiddie pool but it's like pulling teeth to get him in it. Pretty sure he dislikes the bottom of it. He uses it as a water dish though, so not a complete loss lol.
Thank you. It is good shape and works well but I sure do miss the Serdi Millennium the last engine shop I worked at had. One day I will upgrade but for now this will do as I have other machines I still need.
@@whiplashmachine I almost bought a serdi last year but ended up getting a berco ASV-A. It is just like a sunnen vgs20 except the head table on the berco will lock with air pressure so you the cylinder head won't move. I still run the tapered pilots instead of the live pilots like the serdi.
Good to keep your dog away from metal chips and shavings. A friend of mine lost a dog because it ate a bunch of stell filings. The cutting oil they used had animal fat in it and the dog couldn't resist. Poor thing.
Hey mate, I am banging around some ideas about building a destroked 400 drag engine.. Just wondering if I could email your regarding some specs? Cheers from Aussieland 👽 👍
Used to be involved in super late model circle track racing. Destroked 400's were our desired build to stay in 355ci rule. We would use 3.25" stroke cranks and with a 4.155" bore, get 353ci. 18 Brodix heads, mechanical roller cam/lifters, 13:1 compresion, dry sump oiling,,,, Beautiful small blocks. Around 8500rpm's and over 600hp with little carbs. Rarely build anything like that where I live these days, different scene altogether. Whiplashmachine@gmail.com
Hey Mate ! I raced a sprint car with the World of Outlaws in the 70s and 80s with a 400 cast iron block bored .030" over with a 3.625" destroked LA billet stroker crank with 6" rods and 13.5 compression with total seal rings. We ran 100% methanol which was about 140 octane. It was a 393 and made gobs of power and torque. I've still got it and will find a donor vehicle some day. Good luck with your build ! Cheers !!
With a redline like that you must need rocker girdles and an expensive valvetrain, how long between rebuilds too? I've decided for mine I will go with a 434 stroked dart 400 block and cam with a 7200 peak so as not to need a crazy expensive valvetrain and to minimise on parts that are getting harder to find and more expensive.
@@shoominati23 I had Brodix 10 heads with crower stainless rockers. 1.6 ratio on intake and 1.5 on exhaust with the magneto rev limiter set at 9,500 and locked advance . I sure miss those days !! I've still got the short block, roller cam and rockers and rev kit with Earl Gaerty single throat fuel injection. I'll find a donor car one day for it.
I've had a few 400's in my 69 Nova, and NEVER had steam holes in any of my heads. L.A. to Nashville on Power Tour 1999 with iron Bowtie heads-no problem. My current engine I built 16 years ago-AFR 210's with no holes. Street driven thousands of miles, hundreds and hundreds of dragstrip passes-with and without a 200 shot of nitrous. No issues ever.
Hey man good advice I got a 74 400 small block 511 block and I was going to get some aluminum heads for it but everybody else I've seen has drilled holes in them I thought the steam had to come out of the block
@@awfulcoffelsonecargarage8215 Working in my third automotive machine shop, just happen to own this one. Previous automotive machine shops we ALWAYS drilled them. First shop specialized in Short track/bracket racing and other high performance engines. Very common engine was for Super Late Model class which are typically 400's destroked to 353ci. We drilled them all regardless of what word on the street was as the boss man said he been there done that and saw more problems with the non drilled heads. Only reasons I can come up with not to drill them is either too lazy or not equiped.
reallt don't need to drill upper steam holes as any bubbles/steam will flow out the to[ coolant holes. the lower holes are a must as the steam is trapped by the siamese cylinders.
It's been nearly two weeks, how is your recovery progressing? I purchased some E-Tec 200 heads some years back for a Chevy 400, and Edelbrock recommends only drilling the steam holes in the exhaust side.
@@ronnelson7828 Still struggling with Davids mean words 🤣 Two reasons for not drilling them. First is some heads do not have any part of the cavity under those locations to drill into. Second, is that to drill on the angle required to break through into the cavity, you need some precision with the location and the drilling. After 20 years of machining engine parts, I have seen hundreds and hudreds of fails from "home assemblers/builders". So it is best they not even try. I have had to weld heads up because someone tried to drill them steam holes and went right through into the spring side of the head. First engine shop I worked in specialized in stock car engines, mainly for super late model class. We drilled every single one. I will continue that program until some one can come up with an actual reason not to other than "we never did that and had no problems". Which is what I hear the most.

Beautiful dog! Hey how are you anchoring the head down at an angle like that? I am trying to figure out some new clamping methods for my S&G machine. could you show the bottom piece?
I will get some footage of it for you.
Hand drilled my cyl. Heads 3/16 “. Tits - Never a bit of trouble . 1.94 intake valve
Why are the steam holes on the intake side drilled at angle?
Because the casting is not hollow directly under them hole locations. So we drill at at angle to break through the casting and into cooling cavity
I'm glad you asked that. I learnt sumpin'
GM racing said if not operated under 3000 RPMS no need for the steam holes
sbc 400" heads already have the holes
But many aftermarkests dont, hence why this operation is required
My Shepherd and chow like water. My Husky Shepherd mix doesn't. No water source close by so we just fill up a plastic kidde pool.
My dog loves water but he won't go near a hose, sprinkler or any form of manhandled water source lol. We got him a kiddie pool but it's like pulling teeth to get him in it. Pretty sure he dislikes the bottom of it. He uses it as a water dish though, so not a complete loss lol.

FNG here, what is the purpose of the steam hole?
400 blocks have steam holes that go into the heads. These heads didn't come with them though. So had to drill them.

If you don't have a drill press you can do them with a hand drill here....ruclips.net/video/fk4KLjbVDbI/видео.html
You don’t need to drill the steam holes in aluminum heads they cool good enough on there own which I didn’t and I still drive it today with no problem
Good to know. My first day so still learning here😁
