My installation was in a rear sump smallblock Had to go rear sump after designing my own k-member and installing a r&p. It was an old Milodon pickup that was designed for a Hemi. I installed it in a smallblock. The pickup had a couple 1/4 inch ridges on the edges to keep it off the bottom of the pan. I used a rather large pickup tube which is the reason it takes a few seconds to gain oil pressure I reduced the tube considerably because the threads in the pickup were huge. Next time I open it up I may go a little smaller on the pickup tube. I wouldn't think the length would be a problem but the diameter could be.
