I didn't want to hijack Andy's billet pan thread, but the discussion moved to pumping losses and the effect of main web windows on power. So lets talk wet sump pans: is bigger better in order vis-a-vie pumping losses? I have a Dakota, so there is no center link or k=member in the way, and I'm modifying a circle track pan (dropping the sump 3"). This thing will be huge but since it started as a circle track piece, it is boiler plate heavy.
It may be ugly, but it sure is slow.

Cab, I have a full kick out and am looking at mounting options for a scraper. The best way seems to be welding tabs to the tube that let me put bolts in on that side. I have a pan evacuation system, but no vacuum pump. I cut this pan apart to rework the baffles from left turn to straight as well as lower the sump. I'm using trap doors to hold oil around the pickup.

Yes, I'm pretty sure most everyone will agree that bigger is better on a wet sump pan. The only trick is making sure that you have an actual sump for the oil to collect in at the bottom of the big pan.
I'm not sure if kickouts work on Mopar big block engines since the skirt is 3 inches deep. There are people who window the block to get a kickout and maybe that works for them. It certainly takes a bunch of time and money to do it.
For a wet sump dyno pan I usually run the sump about 12 inches deep like the one in this picture. With a deep pan like that my front tires would be in the air setting still.
it's ok to butt heads, just don't do it with a butthead

A pan with the deepest sump the chassis will allow will control the oil the best. The area around the pump or pump pickup needs to be relatively small, trap door divider close. and top plates to get the cover even closer to the pump/pickup will keep oil from sloshing up as much at the launch and at the shutdown.

When done, mine won't be far from the picture Andy posted, but it's a small block. Don't have final dimensions yet, but it won't be 12 inches deep, more like 9". It will have plenty of volume, since the sump is 15 inches square.
It may be ugly, but it sure is slow.

After reading these postings I got thinking that it seems mopars are the only ones I have seen these real deep pans . I know back in the sixties there were some on chevy's but now that the cars are lower most run a dragster type pan or kick out type. Being that chevy cranks hang out of the bottom of the block to start with 3-4" , the 6" theory would mean that the oil level would start at 9-10" from the pan rail , then add on the rest of the pan for capacity. I know in a perfect world it would be better but most of us don't.
