Hi All, on the moment I am almost ready with restoring a Gr4 with aFontana engine, ( weber intake)
How much oil must into the catch tank from a 351 Fontana dry sump engine ?
And which type of oil is recommanded ?
thanks
Simon

It depends on the reservoir tank capacity, Peterson (dry sump component manufacturers) recommend about 2/3 full as a guideline to start on a fresh engine then let that cycle through the engine and see where the level is. Oil viscosity depends on the engine tolerances, but I use 15-50W racing oil.
Thanks Julian, think I have a 4 gallon tank (15 liter) I will fill it with 10 Liter.
the 15W50 Racing oil, is this a classic oil or synthetic.
was thinking on use a extra sinck oil .

I would expect your oil tank to have two screens. The oil level should be between the two screens when the engine is running at idle speed. You can run with the level just below the upper screen if you want to carry more oil, but stay below the upper screen when running.
On my oiltank there are no screens, also no oillevel clear hose
