Will this work in a 1991 OMC King Cobra 454 HO?
No. The thermostat for your engine is 3853983.

Dimensions of this thermostat? Height below and above the flange?
Sierra does not have that information. We can only match up thermostat by application and OEM number. If you can call us at the number at the top of the page with your engine model number we can take a look.
