<< Working for ford i should be able to answer this... SHO stands for Super High Output and the 93 uses a 3.3L engine i believe...the more current ones went upto 4.0 and 4.6 >>
Working for Ford, you'd know that the engine in the lastest SHO's was a 3.4L V8 (1996+). The 1989 to 1995 models had either a 3.0L or 3.2L V6 depending on the transmission. 3.0 for mtx, 3.2 for atx when they became avaliable.
The 3.0L in the manual trannies had a 3.5" bore, 200lb-ft @ 4800 RPM, 220HP @ 6200RPM. The 3.2L in the auto trannies had a 3.62" bore, 215lb-ft @ 4000 RPM, 220HP @ 6000RPM.
