While it is true that muriatic acid will dissolve die cast pot metal, I have never had a problem with muriatic acid "eating iron". The acid reacts only with the rust and you leave the part in the acid just long enough to remove the rust. The result is clean fresh cast iron. I have soaked several rusty intake manifolds in a large tub to clean out the insides and never had a problem. Just make sure you remove and neutralize all of the acid before painting. Your housing should seal just fine with a new hose and tight clamp. Racers have been using Muriatic acid for years as a porting medium. Coat the passages, let it sit, sand blast, re-coat the passages, let it sit, sand blast. Enlarges the passages and keeps the shape. It's called "cheating fairly" to those who do it. YES, Muriatic acid will eat cast iron and ruin it. As someone who has been porting heads and intake manifolds for the better part of 50 years, I have personal experience with Muriatic acid porting.

Aside from rust, what is the best way to remove thick, heavy paint off of y-block engine parts?

All my parts were really gunky. Especially ones near the bottom of the engine. Probably a quarter inch of road grime and grease. I found a torch and scraper works great on bigger parts. Smaller parts I put in a pan with acetone and use a paint brush and the crap just falls off. Watch out for rubber parts tho. I started off using a Dremel with wire wheel attachment. Was getting too many wire strands flying everywhere. Wire wheel attachment on a drill works good and not so many loose strands.

Hey miker, tried to pm you but it says you have too many messages and I can't send you one. You need to delete some messages it says. Come on down to Sierra Vista some day

get some molasses,cattle feed store is best price mix1qwort to2gall water leave the housing in the solution for minimum 30days also in a warm aria
it looks like that engine has never had any antifreeze or water aditiv to stop cavitation..go to truck repair shop and they can help you with modern additives for deisel engines.
what does the rest of the visible water jacket look like

Engine just came back from the mechanic and it was hot tanked. All is good. Did they even have antifreeze back then?

Maybe a rhetorical question, but yes they did - the antifreeze part lasts a very long time but the other additives, like rust prevention, does not last a long time. That is why it should be changed after 4 or 5 years (Today's type). Used to be three years . B-rad (1/29/2023)
