the lincoln block is Teksid just like the 96-98 cobra blocks. i believe it had a cast crank, never taken one apart. the block is a 6 bolt mail just like the cobras. the heads are the same and they have IMRC like the cobras. the difference is in the intake cams, around .010" less lift. also the intake manifold is different, and not something you would want in a mustang.
