Where could you find that factory turbo charged motor and/or cyclone b/c they are pretty much non-existent. Theoretically Could you swap vortec heads from a 94 onto the turbo charged 4.3(92-93)?

they made the typhoon in 94 also. i think the heads r a lil diff but i'm not sure. u could swap the engines. if u look in the performance forum on here there is a guy that put a turbo from a sy/ty on his 98.
