    Another chapter in your book. I was taught to deburr a block by using files. Yes files. With a file your chamfers are smaller and work just as well. You are less lightly to screw something up and you can file to the outside of the block keeping less shavings from inside the block. My son was taught using files. Look at the work, Decide what you are doing, Go slow.

      I've half decked a Hercules 6 cylinder with a file.
      It was way out in nowhere land and would pop a head gasket every 2-3yrs.
      I pulled the head and the deck had all kinds of gouges from a crappy deck job.
      Anyways ,2-3hrs of filing off the high spots , new gasket , havent heard from them in 7-8yrs now 😁
      And for some bodywork lately ,it's been real handy.
      I took some welds down to surface on an aluminum fender and polished it and it's mint.
      You can feel when the imperfection is gone because the file glides across and removes almost nothing.
      Good stuff

    Most of my own builds are small and big block Chevys. Your comment on cracking in the main webs is exactly why I, unlike many others, avoid factory 4 bolt main blocks. Most, if not all stock Chevy 4 bolt main engines have the outer bolt holes drilled straight into the web parallel to the inner holes and crankshaft. If I'm building an engine for a daily driver or a mild cruiser that won't see the high side of 6000 rpm, I'm fine with 2 bolt mains. If I'm building a race engine that will see high rpm, aftermarket main caps with splayed outer bolt holes and the extra machine work required are the only way to go for me. I also chamfer or radius EVERYTHING! I'm not giving cracks any chance to start!

    It’s amazing how much flashing is in a production engine. I cleaned up a pair of heads for a truck I owned years ago. Flashing down inside the valve bowl area. Talk about restriction. After cleaning all that up with a die grinder, port matching to the Edelbrock headers I bought, new set of rings, wow! What a difference it made on my daily driver. Time well spent!
    Oh, and by the way, I always chase out the bolt holes, in the blind holes, I use a bottom tap.

  • @mpetersen6

    There's another factor in coolant passages. Dead zones as far as coolant flow goes. For an example on AMXJ's UA-cam channel he has a series of interviews with an individual who was involved in cylinder head porting on the 4.0. One thing th heyfid was install thermocouples all through the engine. One of the things they found was dead coolant flow towards the rear of the block between cylinder cores. A fix for this is to install exterior coolant lines to shoot coolant right into those areas. This could be done on any engine that has hot spots caused by uneven coolant flow. Aldo the farther the heat source is from where the coolant is introduced to the block or head the hotter the coolant is by the time it gets to the rear of the block or head.
    Overheating kills more engines than anything else. This is one reason the Lemons for example requires only wayer as coolant. Second is probably bearing failures due to lack of oil pressure and flow.
    As for blocks splitting under high power loads, detonation etc. One thing the manufactures could have done is to have a web cast into the blocks between the cylinder banks. The webs could have been cast almost as high as the finidhed ends of the blocks. The cost per block would have been negligible. But weight was probably also a factor. In many ways the US auto industry penny pinched itself to death. Look at a lot of the imports. Even on four cylinder engines they employed deep skirted blocks.

    A twist drill with the tip ground flat works great for cleaning the crud out of bolt holes. Turn it by hand with a file handle or a pin vise to avoid damaging the threads. An old drill chuck makes a decent pin vise if you have one kicking around. You can even use locking pliers in a pinch

    You mentioned the oil drain back holes. VERY important. Even for a stock engine. The one I rebuilt for a 71 Ford showed sings of lack of lubrication everywhere.

    Block prep offers a Zen-like experience. Every minute you put into blueprinting the block pays back in satisfaction of effort. I always remove as much slag as possible, especially in valley vent holes.

    I've mentioned the fire survivor 454 RV engine that I have on here. I've finally gotten into it but I'm in no hurry. But I've decided the direction that I'm going with it. Machine shop first. It went through a bad fire so it gets a hot bath. Then 30 over. Then the deck gets lowered. I'll take care of those stress points myself once I get it home. I'm selling the heads and going with square port aluminum heads and a roller kit. Adjustable timing gear with quick access cover. That's as far as I'm gonna plan for now.
    It may be a big block but it was in an RV. Which means it has a high deck.
    A torque monster basically. I'm looking for HP. I'm talking about it in here because Tony's channel has me wanting to tackle a project. Hell I might even video the process. With my trucking job it'll probably take me until well into the summer to finish it.
    Wish me luck.

Two, the 366 and 427 were the only tall deck blocks in trucks (i believe the 572 crate engine uses a tall deck). If you can fit your finger between the side wings or ports of the water pump and the bottom of the cylinder head, you have a tall deck block (typically seen in commercial box trucks). If the water pump outlet is flush with the deck surface/bottom of the water pump, you have a standard deck height block.

    Have you ever stress relieved a block?
    Like say put it into an engine oven and bring it up to about 850F and then let it slowly cool over 12 to 24 hours?
    [the process is different for an aluminum block and its at lower temperatures]

    • @hunnybunnysheavymetalmusic6542
      @hunnybunnysheavymetalmusic6542 2 роки тому +1

      Side point: heating the block to 850F will pretty much break any rust in the jackets because of the massive difference in their coefficients of expansion.
      The rust will pop off.
      If you wanted to get stupid crazy, once you have gotten all your rust out, you can soak it with ammonia or urea and nitride the block, but one has to be careful because that causes GROWTH which can RE-stress the block all over again.
      But, still...putting 2 to 3 thousandths of an inch of nitrogen into the block will really help reduce RUST and WEAR.

    • @hunnybunnysheavymetalmusic6542
      @hunnybunnysheavymetalmusic6542 2 роки тому +2

      @@bcbloc02 If you do not have an oven designed for this specifically, you have 2 initial choices: 1, cough up the money for a pre-made one, or 2, get out your builder skills and some tools and build one yourself.
      You need to consider this first.
      While there are a lot of ready-made designs out there, both free and purchased plans, I do not know of any of them which incorporate aircrete, but I would most definitely advise using it between whatever your outer structure is, and your inner refractory lining, both for stability, keeping out drafts [oxygen] and insulation [without insulation your cost of operation goes way up, especially if you plan on nitriding, or carburizing any product].
      You CAN 'carbo-nitride' products, but, since most 'cast iron' blocks are, in fact ultra high carbon iron [higher than 'steel'], adding carbon is not what you need at this point, obviously.
      While Nickasil is another option, its complex and time consuming, not to mention deals with a lot of highly toxic chemicals and extreme precision which can mess with some people.
      Let me follow that up with the fact that, with some machinery, nitriding too, can some times involve at least one very toxic chemical [cyanide in one scenario, and ammonia in another one], although if you go the urea route, you don't have that problem.
      The 3 major chemicals used for nitriding [there may be more, I am not sure, although I do eventually plan on experimenting with other nitrogen compounds such as melamine, hydrazine and metal azides] can be obtained, with varying levels of difficulty from various sources, locally and online, depending on where you live, and what laws apply.
      By nature, I would tend to avoid cyanide simply because it can kill kill a person so fast, whereas ammonia is many times safer, despite having its own hazards, and urea, while seemingly easy to use, can, in some situations, lead to a few potential hazards, so one should never be careless when handling these chemicals.
      From there, you are going to have to consider how large you can go, because an engine block, as you know, is no small object.
      You are going to need roughly the volume of a 4 foot cube worth of space for a nitridation oven large enough to hold a decent sized V-8 engine block.
      Inside the insulated, draft-proofed oven, you will need space to put a 'sealed-yet-vented' box that you put the engine block and the nitridation feedstock so that it can be either lowered in via hoist, or rolled in at ground level on wheels.
      If you can not get stainless steel, it would be best, where possible, to nickel plate your box, because otherwise its going to rot away as it is force oxidized on the outside, as well as it will warp and buckle as it grows, soaking up nitrogen from the inside.
      The reason I put 'sealed-yet'vented' is because you need to make certain all of the oxygen is extracted, but at the same time, you need a vent where the excess gas can escape so the box does not warp or rupture.
      The trick is to have a small [very small, actually, 1/8" or 1/6" pipe size with a stainless steel check valve] vent which you can both attach a vacuum pump to initially to extract the oxygen, and then, when it warms up, allows it to not only continue to exhaust any other oxygen you could not get, but release excess gas when the temps get high enough that the box could potentially warp or rupture.
      The thicker the walls on the box, the more resistant it is to deformation, although at the same time the slower it will heat.
      You need to have enough heat, over enough time, for the nitrogen to soak into the metal of your part to the desired/intended depths.
      But never forget, nitriding metal changes the geometry/dimensions of the initial part.
      This means, as the metal 'swells' / 'grows', your initial dimensions are going to be totally thrown off.
      If you are not prepared to deal with changes in material dimensions, it is best you not try this, because it can totally throw off your entire block so that things like valves, camshafts and freeze plugs no longer fit.
      And boring/grinding AFTER you nitride, well...
      It fully defeats your work.
      You will grind off the nitriding.
      Therefore, typically, engineers who plan for parts being nitrided will prepare by over-sizing the clearances of the part, so that when the nitridation is complete, the part ends up in the final intended size/clearances/fitment.
