    If I may ask; What is the compression numbers? Suprise the seller with that as oil can be added to UP the numbers. Run on a boat if possable to be sure it shifts then drain a little in a glass jar, just enough to coat the glass. Let it run down the jar & look for pieces of “glitter” metal in the sun light.
    Wish you well!! P.S. Ask why he is selling. Does the block still have a lead seal? Tank?
