I believe we are talking about an 18th Series model 1350 180 Limo. So... yes, it should be a 356. I think the early 356's had the filter in-line between the pump and lifter gallery (no by-pass plumbing). The oil filter canister had a relief spring at the top of the tube to allow oil to by-pass the filter if it became dirty and the pressure built up (this is why it was fed from the bottom and not the side). The early engines did not have a return port into the oil pan for by-pass plumbing. It sounds to me like tolandis is trying to provide some by-pass filtering while still maintaining full pressure to the lifters without the benefit of the later by-pass plumbing enhancements. He doesn't want to drill the block to provide the return which I can understand. It has been suggested that the return could be drilled into the base of the oil-fill tube thereby providing the later by-pass strategy with only a hole in the easily replaceable fill tube. That's the route I'd go. I wouldn't worry about too much oil going to the gallery (only too little).
