I have come across a block that is filled to about two inches from the deck with block filler. It is an old fill so it is the concrete looking fill instead of the more modern epoxy.
The block is.....and this hurts...a 1966 426 Hemi. Otherwise it is in great shape. No damage, standard bore and was running when it was pulled out. Lived life as a drag car only.
So, Hammer drill and masonry bits, muriatic acid or ??? Any hints, tricks, or old timers solutions appreciated.

Some thoughts: 1. It's a '66 Hemi block and would look nice sitting in a street car, probably go nice too. I imagine that's why the question. 2. Before you do anything else, Magnaflux or dye penetrant check the block bottom end for cracks. 3. If you have 2" of space at the top it'll probably work on the street if you pay attention.
R. This , add an oil cooler and you should be ok for the street as long as you aren't idling in a line waiting to get into someplace for an hour . Question though apollo , have you checked the deck height ?? Many of those drag hemis had the decks cut ... to the tune of .100 or more.
running up my post count some more .

Here is the Mid-Day Update and answers to some questions. The reason for trying to extract it was correctly answered. The block looks to be in great shape. It has a standard bore and I can get into a Hemi for a really, really good price if I can make this happen. **note** the price of a MoPar/Cummings era reproduction bare block is around $4500. I would like to get as much out as possible and drive it with no restrictions. If this were a small block Chevrolet 350, I would have made an 8 hole flower pot for my mothers front yard already. As far as the deck height, that is a question that I did not ask , but will. Very good info and thank you for that "question to ask" that I didn't know to ask. **note** the heads are Aluminum 1974 Mopar heads and in good shape. The engine was running when torn down. Anything other than the magnaflux and pressure check on the heads to ask? On the topic of muriatic acid. I have seen a video were concrete was dropped into a container of the acid and began to dissolve. Why would this filler not react the same way? What are the properties that make this different? I have seen a bucket of filler and it appears to be just a finer powder than that of sakcrete and just add water. Also, I have seen where people have used muriatic to clean parts, so would a concentrated amount damage the block? Is there a time limit on exposure, etc? Again, rookie questions, I have never done that. Is there any masonry bits, or diamond tip bits that would cut into the filler without the effects of the more violent hammer drill action. I guess more of a boring action than chipping? I want to say thank you in advance and that I am writing this with an inquisitive tone only. I am not challenging or questioning the integrity of anything written above, I am asking to clarify what has been written. I write this because the written word carries no inflection of voice and can be taken the wrong way. I try and ask as many questions from as many different angles as possible( Technical, Scientific, etc ) to get the best understanding of how to attack a problem. The General board sometimes gets bent out of shape when you start asking questions about what they write.

If you have intentions of using this block for yourself for a street car i don't feel you would have any major problems doing so, that being said the only thing's that I would do would be add a good oil cooler (as mentioned before) and you may look into a reverse cooling system (indy makes a plate for that) that flow's the cooled water back thru the head's first and that to me would be where the greatest amount of heat will be is in the upper part of the block, if this block is as good of condition as you say I don't personally think I would risk the physical damage of trying to remove it, to me the worse thing would be the added weight on the front of the car.Just my opinion

Thank You and keep it coming with opinions.
Dartman366...I will research the reverse cooling. That makes sense in changing the flow with the coolest part of the liquid coming into the heads....and also mentioned about a heavy duty oil cooler.
Indcontrols...what type of machine did you use for pressure. A regular deck pressure washer or something specialized, About how long of a process did it take you, Also , how much of the filler actually came out?
Zooom....Roger that on the Muri-Hydro acid. I will scratch that from the list.
Rebel....how long of a process to break that filler up if I just let it soak in a barrel of antifreeze? I didn't think that stuff was that caustic. Again, Just being curious.

Maybe E85 fuel. Option 2, Blower, injector hat and methanol

Just a note on the muriatic acid. As it might eat away the hard block slowly it will also eat away at the block material at a faster rate. Also if anyone is thinking of using muriatic acid for rust removal , don't do it in your garage, the fumes will kill you before you can get out, also the fumes will rust every piece of bare metal in the garage. Do it out side with a good breeze blowing away from anything that you might like to keep, also wear rubber gloves and eye protection . I other words, muriatic acid is some bad $hit.
it's ok to butt heads, just don't do it with a butthead

I bid on a filled 66 block at an auction, and dropped out against the other bidder who later told me he was going to send it to a shop in Florida that could 'sonic' clean out the filler. Never heard of that before. I think this would be the only option I would consider if I was set on removing it. I would think there should be a frequency that would deteriorate the filler without damaging cast iron. But with that said, I probably agree with the "install GOOD oil cooler and run it" option, using a good synthetic oil for it's higher temp tolerance.

Rebel....how long of a process to break that filler up if I just let it soak in a barrel of antifreeze? I didn't think that stuff was that caustic. Again, Just being curious. The Moroso was about 4 months old by the time the engine was assembled & running. Antifreeze was added due to the alloy heads & the chorinated tap water was harsh on everything alloy. It was noted that there was a soup in the radiator a few weeks after the run in period, so everything got flushed. Since there wasn't a cooling problem after, it never got looked at again & the engine got used. Because it had an overflow bottle & a suck back radiator cap the overflow bottle was the reference & it never looked bad. The fresh soup had jammed the rad cap up so the flow was blocked both directions. Months pass & there's the odd high temp noted on the guage but it cooled down. Eventually it turned to a horror story, the engine running like a steam train, the engine got pulled. this mud like soup was everywhere. after the big strip & clean we found the Block fill was all gone????? this was the soup & the cooling system was only filled with water & antifreeze. I think the electrolosis of the antifreeze reacted with the block fill & just ate at it till it was all gone. i dont know if soaking it would do it. i think it would need circulation.

Thank you for the replies!!
Evil Spirit..That was very interesting so I checked into the sonic cleaning. I haven't as of yet found anyone who has a tank large enough for a engine block. Although it looks great for cleaning small parts every nook and cranny from grease , rust etc..
Rebel....Thank you for the update on the antifreeze information. I am going to try it and see. It may take the combination of antifreeze, heat and circulation. I have a few ideas.
Lock jaw...I am not 100% sure on the magnetic question. I was able to scrape some of the filler off and it didn't seem to have a magnetic quality. But, it was a small amount and I really wasn't looking that specifically. I will re-examine that soon. I can say that this was done many years ago. Late 80's possibly.
Again, Thank you for these excellent ideas and information. This is why I keep coming back to MoParts.
