Haven't been here for awhile. Yet another new project in the works now.
I picked up a 500" KB Mopar aluminum block with original B1 heads. I'll have to rework some things from the previous use as a roundy-round motor. Originally was set up as with a dry sump oiling system and still has the oil pan. No pump, mount, drive system etc.
Converting this to a drag racing setup for a 70 Duster. Looks like I could go external wet or dry sump. I get the advantages of less oil in the motor with a dry sump, but is the benefit worth the potential $4k investment? Being an aftermarket block, I don't see any provisions for internal oiling which is fine. Shooting for 10.0 up here on the hill.

As a bracket racer no benefit. As a corner turner it was useful to control oil slosh in the turns. A proper baffled pan and an external pickup and your all set.

Looking at how the pan is configured, everything is on the right side so I would have to probably add some fittings anyway. Not sure if having the kickout on the right side would make much difference if there was 2 outlets on the back.
What all is involved in designing a system that works? Looks to be confusing as to how many stages etc.

IMO for a bracket car it is NOT worth the expense in a Mopar block design. If you are looking every last little HP then its worth looking at. Otherwise the extra expense is better used elsewhere.

I don't think it would make enough of a HP difference for my goal. I figure if I ever want to change it later, I can add some boost to it.
Motor came from Ohio. Some dirt track car I guess.

A wet sump is close if the pan is deep enough that the crank is well above any oil level including high G and high negative G. Really de-aerating oil requires a tall vertical tank, air comes out of suspension as it passes through. By comparison, a wet sump may only be a few inches deep and returned oil may reach the pickup in seconds, unless the pan is very baffled to form a labyrinth.

I think the main reason for running a dry sump for people like us is they look sexy. To me a lot of the fun of working on these cars is the beautiful parts we have to work with.

I only wish I could afford a dry sump pan for my Hemi, because if I could afford the dry sump, I could afford to finish my car...
