    Default Oil weight and capacity for 5.7 Litre Magnum 350

    I'd like to go with a synthetic but not sure what weight this motor needs. It has about 600 hours. Any tips for bringing it back to service after sitting for 1.5 years?

    Can I get a regular automotive oil filter or does it need to be a marine (Part Number)? Does anyone know where I can get a manual for this motor online?

    Thanks!
