Engine cleaning after terdown, before final assembly?

Hello,

I tried to search for an answer but did not find a solid one.
I am in the process of assembling my 327 small block. I had the cylinders honed, back from the machine shop, but it was sitting in my garage for couple of months. the outside is rusted, and inside all the casting, also in the waterjacket. the cylinders were coated with oil, so those not rusty.
What should i use to clean inside and out to prep for assemble, and paint outside?


Thanks

If you can't get to the rust with a grinder or sander try this Fast Etch from Eastwood. Look around on their website for some more products.

Cleanliest is utmost importance in any build.

After my motor is back from the machine shop, after mill or bore work but before cam bearing are installed and with all cam oil galleys plugs out and tapped for screw in plugs, I was my motor with solvent to remove the remaining oil . Once that is done I wash the motor entirely with SuperClean , the purple stuff or something like that. I clean out all oil passages with a rifle cleaning tool.
I hot water clean manually , paying close attention to the new bored holes , water jackets and passages.
Once satisfied you can eat off this motor, I spray cly bores with light oil, WD40 will work.
I use lint free rags to wipe down and blow out everything.

I install my cam bearings and I now am sure there is no metal shavings in the oil galley behind the cam bearings.

Some guys go to the extreame of painting the lifter valley area with hi temp GE Glyotal paint to speed oil in valley area back into the oil pan.

Everything that goes into the motor , is inspected , included the oil pump.

Hope this helps

I actually bought the engine brush set from Summit, I already cleaned through all the oil passages, and all, it just rusty, especially the water jacket, light surface rust everywhere. I want to get a rid of that and use a cleaning agent what prevent from future rusting.
Or I worry too much? The engine oil and filter will take care of that in time?
