I'll be getting the stroker block hot tanked and de-greased, then I'll look into scrubbing the block down with various wire brushes. I know I could do a much better job but leaning over and the engine 'hanging' made it a bit of a struggle. This was solvent, stiff bristle brush, about 3 different stainless wire brushes and some brake clean.
Also got the transmission mounted, and dropped pan to change the filter and replace the pan with the modified one for the transmission temp sensor and reinstalled the cooler lines. Next step is to mount and route everything for the rear mounted washer fluid reservoir.
