Well as far as I could determine this looked like a pretty good block; but who know. No visiable bolt hole problems, repairs, etc. Deck look good, no indication of water corrosion due to a bad head basket. Appears to be standard with a ridge on the top of the cylinders. Appeas to have original caps with no spum bearings. Assembly date clearly visable, so doe snot appear to have had any deck work. Guy was 65 years old with a ton a parts. He talked me into buying a crank and some double dimple rods.
Now, lots of dirt in all the bolt holes and dust caked on the grease in the cylinder walls.
Appears to have been clean after removal, who know when;but my guess would be 30+ yrs, painted with black paint and cylinder walls and main caps loaded up with grease. Was it common to paint these blocks and then grease them years back? Wondering the best way to clean this up for a better inspection.
Mitch is right- take it to a shop and have them do it right...or, spend a day with the carb cleaner and a pressure washer! Ugh- I'm too old to do that crap anymore. The shops have heavy duty washing machines for this kind of work!
That's who I was think of. But now I am just thinking of what I should do to inspect on my own and re-lube and store. I am thinking of just cleaning the main bearing surfaces the cylinder walls, the cam bearing surfaces and re- lubing them. Don't think it's cracked; but who know. When I decided something, then I would have it cleaned, baked, and maged just to make sure.
Can't think of why anyone would go through the work of cleaning, greasing the mains, cylinder walls, and cam bearing surfaces and then paint the whole block, if the block was cracked.
