A friend just bought a 77 eldorado, boat, (425cu in, carb) and just wondering if anyone knows the fluid capacities for the engine oil, and trans fluid...also weights that is recommended...???? Thanks! Oh, and where the fuel filter is located??

There is a FF in the quad carb inlet fitting. Oil is 6 qts 10/30. Trans is about 5-6 qts pan only, always recheck when done of course.

Thank yoU!!!
