i cant tell how to find out its a eci 3000
look on top of the valve caver and it will have SOHC/or/DOHC. that will tell u if its either check it out.
how can i tell sohc or dohc
The sohc will have silver valve covers. The dohc will be black. If you still cant tell look up a picture on google images
If you look under the hood at the engine it will either say SOHC or DOHC which is Single and Double respectivly.
SOHC
"SOHC" Means Single Over head Cam and DOHC means Dual (2) Over Head Cam. Example: on lately Ford Mustangs , It comes with 4.6L SOHC and DOHC Engines, which basically it will tell you whether there is/are 1 or 2 camshafts over each cylinder head.
Sohc
SOHC--Single OverHead Cam DOHC -- Dual OverHead Cam
Not necessarily better just a different technology. Search Google with the term,"DOHC versus SOHC".Not necessarily better just a different technology. Search Google with the term,"DOHC versus SOHC".
all 96 gt mustangs had the 4.6 sohc. only the cobra had the 4.6 dohc.
i believe the mounting is the same however the DOHC will have a better power output than the SOHC
the 1991 3000gt are dohc. it comes stock with 222hp. they also made sohc but that wasn't until later generations of the 3000gt's. The 1991 dodge stealths came in sohc, compared to the 91 3000gt's dohc. either way, with minor adjustments, it will fit from sohc to dohc.
