i know sand blasting the engine and rearend is a nono cuz of the media getting into places it shouldnt be. but what about taking the paint off with baking soda? then dunk it in a electrolisis tank to get the rust/baking soda outta everything? just a thought that i might try if everyone else thinks it could work. im having a heck of a time figuring out a easy way to do it with the cast pieces without messing up the roughness

I would give a steam cleaner a try or take it to an automotive machine shop and have them dip it.

I've taken many nasty car engines, degreased, then stripped with a chemical stripper.... used a small cup brush on stubborn spots... and with a little elbow grease produced show quality results in no way harming the finish of the cast iron. Usually wash with soap and water followed by spraying off with a cup full of mineral spirits in a paint gun prior to paint.

Just a thought, why would you soda blast as it is applied the same way as sandblasting and get everywhere? If you are not rebuilding then wire brush and sand paper. If you are going to rebuild then by all means dip the block at the machine shop. Just my .02 worth

With soda blasting all you have to do is wash away the soda and dry and not worry about sand damaging the bearings. Even if you don't wash the soda away it's not going to harm anything.

I think I would still be worried about contaminants in the soda. But that's just me.

Truth told, soda blasting is so mild you can blast a car and not worry about damage to chrome, heck even glass. Will not remove any rust or corrosion. Does leave behind a residue that if not properly removed will cause adhesion problems.
