There has been a lot of chatter on MLU about rust removal, preparing and working on very rusty assemblies. For example there is a long thread on reverse electrolysis, which brought out many very good conversation points. Then there is a second, and I find more intriguing, discussion of prolonged immersion of large parts in raw molasses. Someone had a before and after photo of a Stuart final drive. Red and scary at first, then steel and clean after. That convinced me.
In your situation, if the engine block has been removed from the frame, I'd favour the molasses bath. You 've already scheduled work on it later in the future. So you have time on your side. Molasses by all reports has none of the 'potential' metallurgical effects that reverse electrolysis does.
Over to you while you do your research. And keep us posted.
