I just got done sealing up my 383 for my superbee. I took all the frost plugs out to replace them with brass units. Well I noticed there was some crud in the water passages. What is the best way to clean out the passages to try and make the best cooling for the car.

No the engine is sitting on the stand still but its all together. I just noticed some garbage in there (almost a clay like substance and some rust chunks) I just want to clean it out.

This car and motor sat from 1987-2003 with the same coolant in my garage. I started it a couple times a year but never changed the coolant that I can remember. About 5 years after I started driving it again the core plugs rusted out. I jerked the 340 out one Sat morning along with the tranny to replace all the core plugs. I used a pressure washer and got the inside of the block clean. There was a ton of junk in there. Sun morning I put it all back in the car and was driving it that afternoon. Felt real good about that. Couple months later the motor won't turn over one morning. Found water in #5 cly, blew it out and the car started and ran fine. After a couple more times of this I knew I had a serious problem. This picture was taken after I had pressure washed the motor clean inside and out. Then took the oil pan off to clean the inside of it out.   Jerked it out again a couple months later and ultimately found a crack in #5 cly. Shoot! Then took another block I had and stuffed new pistons in it and put on Eddie heads I had for like 4 years. Never got around to using them until now. the block I had was still standard bore, Had to wait for pistons like a couple weeks or more because I wanted standard bore. I guess they don't sell many.  The new bullet, I built it at my race shop and brought it home, still running it today. Good luck with yours.

Yep all the pans are on and sealed up. I just was wondering if I should use any cleaners or anything to knock the grime loose?

Garden hose and a long screwdriver or coat hanger wire. Once it's all sealed up and installed a gallon of vinegar in the cooling system cleans the rest up as a cheap cleaner/flush.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

When people tear down an engine for a rebuild why not just have the block cooked. It doesn't cost very much have done and then it is done right. The new solvent used don't even eat up cam bearings like the old stuff did. 
I have always pounded out the cam bearings and had the block "hot tanked" with heated caustic cleaner. Still have access to one. This is the block for the above motor with Eddie heads.
Will a hi pressure parts washer get em this clean? Is that what there using nowadays?

Do you think the cylinder wall crack could have been caused by the pressure washing? Or was it just age and corrosion...  Maybe the hot-tank or garden hose would be safer?

I would of but my engine is not rebuilt. It was rebuilt about 20 year ago and ran awesome when it was taken out. My friend and I inspected it and everything looked great inside so we regasketed it and upgraded it a little. I wanted to install brass plus so they don't rot out and noticed all the crap in there.
Heck yea, now is the time to clean it out of course and a garden hose will be fine along with a small diameter brush.
My cylinder in my block cracked from neglect during all those years of storage.imo And I'm sure I speed-ed it up by cleaning it up when replacing the core plugs.
If your block is to the point where a pressure washer can hurt it, it's junk anyway or will be soon like mine. lol

About 20 yrs ago Doug Dutra the /6 guru used a percentage (not sure how much) of muriatic acid/water iirc & let it sit overnight & it got the insides as clean as the block several posts back. I do think the scale buildup even a smooth baked on coating of it inhibits heat transfer a fair amt

Here in Md I cant find a machine shop with the old hot tank cooker thanks to the envierment people
Thank you envierment(enviroment) people! Now I can find rivers and streams to fish in when they were non-existant in Ohio before 1970 and clean water to drink..
Ron, Don't be too disheartened because when the EPA is dismanteled we'll be going back to cleaner living.. 
but back to the subject... why not seal it up mix up your own solution to let it cook for an hour? Drain cleaner and water? Pepsi please?

I wasn't knocking them but I guess it sounded that way. I understand why they do what they do. I guess I just hate that my blocks dont get cleaned as good as they used too. Ron
