Aluminum slant (not mine) for sale. Wish I had the money

Post is gone, but I recall seeing it before. At least he has the head off so you can inspect the block surface. Many became corroded beyond re-use. The aluminum slant needs a special head gasket. I think it is now available special order (Corteco?). A hot rod magazine article compared them and found the aluminum slant no faster in drag tests, which they attributed to the block not being as stiff as the cast-iron ones.
