Help needed with sb 318

Pull the pan and find out where the oil pump foot is. If its almost sitting on the bottom (1/4 inch) just fill it with 5 qts, find a long dipstick and trim to register full at 5 qts. I doubt your going to starve that beast running 2500 RPM all day. I bought an 86 D250 360 LA 4bbl and it had a huge alternator, a little like that one but I think the mount was different.
