I may part with one of these longblocks. Preferably the stocker build.

Research shows X block is 3-speed...XW or W added in front of the number sounds like what was explained to me as the factory using 3-speed leftover blocks in four speed cars. Now...the plot thickens. PHS on this car lists it as an M-20 car...but lists the engine code as 76x. Four barrel cars were 78x according to PHS, that is. That said...either would work for me...and also prefer the stock build. How much? And some details if you could. Much obliged!
