I've been a hoarder of BBC stuff for a good while, which brings me to the question in the title. There's a 70/71 402 chevelle/monte carlo suffix partial short block that's been here forever would make a nice builder, steel crank, and dimple rods. Nobody wants it because it's an 854 casting 402 block not some coveted 396 casting, nobody wants the crank because it's turned .020 even though it's all very useable. Should I just throw it on the scrap pile or content to hoard it? Also on the pile is a set of 69 427 corvette exhaust manifolds. Keep or scrap? And a 71/72 402 287 casting Camaro intake manifold. Keep or scrap?
