Ok I know there's a bunch of go parts for the windsor like alluminum heads trick flow, edlebrock, ford motorsport ect, but I wasn't aware of any design change in the factory iron, could it be the Ford triton motor head? I'm not too knowlegable about the later factory iron of the 90's to date.
OMC used Fords a lot.
When Volvo and OMC went into the joint venture, they used the 5.0 and 5.8.
When Volvo bought out OMC Ford engines ended. That was in 96, so no "To Date" engines.
There was also carbed and EFI engines. EFI started in either 92 or 93 at OMC, Volvo came into the picture in 94.
