I've got a 1995 Sunbird 170SS. It's got the 3.0GS sterndrive. the Engine and outdrive has OMC Cobra written on them but the tag on the valve cover of the engine says 'OMC manufactured by Volvo Penta'. Which is it? did volvo supply OMC with engines and drives for this year? Also, would this make the outdrive an OMC or volvo? Thanks in advance
