In 1988 Patrick Dykes was selling NOS GMC 302 shortblocks for $500.00 each. i bought one and still have it.
Any New Old Stock part or collection of parts is . . . New--that is, never used . . . Old--that is, subject to the depredations of time, not least of which are corrosion and dirt . . . Stock--what the factory specified in weight and performance.
At the least, any NOS assembly like this should be torn down, cleaned, checked in all its dimensions, and reassembled as we should assemble any engine we have "rebuilt." Most of us would, i think, want to replace many parts with an eye to performance and durability.
Bought right, it's a great opportunity.
God's Peace to you.
