I just put my stock oil pan on my 440 Source stroker motor. I used putty to get the pickup at about 1/4" above the pan bottom. No problems. The issue is that the edge of the pickup is right against the oil drain hole. It may make draining the oil a bit slower, but probably ok. It just seems odd. It is the replacement "stock" pick up from 440 Source and does not seem much different from the old stock one. I cannot compare perfectly, because the old one got twisted. Anyone have a similar problem?
