1976 Olds Omega help!
 

Hi All,

I have a 1976 Olds Omega with a 350. however the engine that is in there does not appear to be the correct year. I was wondering if anyone could offer help on what the engine would have been in originally:
Engine # 55752 -3A

Also looking for the specs of the engine...

AND
are the intakes on the 350s all the same?

Thanks
