Oiling system I am currently building a Warhawk LS7X 9.8" tall deck nitrous motor to go into my 2002 Trans-Am. The motor will be a solid roller and drag race only. It will be a 4.125 bore X 4.250 stroke to make it a 454. I plan on spraying 500 to 700 between 2 stages of direct port. I will only be spinning the motor to 8,000 RPM's max due to the longer stroke. I will be going with a Jesel belt drive. My question is, should I go with a dry sump oil system or will the conventional oiling style system be ok for my application? Thank you.

Oh yeah, I am not worried about the cost. I am not going to ruin my 30,000 dollar motor by being cheap. I just don't really know the purpose of the dry sump oiling system. If it will be the safe route to go with my motor, I am all in and will get one. I see a Aviaid 4 stage system for sale in the for sale section on here. I am looking for the reasoning of getting the dry sump system over a conventional oil pump system.
Drag race only, I would just get a good oil pan to control oil slosh and an accusump. Dry sumps are good for road race where high g loads push oil away from the pickup. Nothing wrong with one in a drag car, but an unneeded expense in my opinion.
The accusump will retain oil pressure if something happens and the oil pressure drops for whatever reason.

Besides reducing windage loss a dry sump guarantees a constant oil supply to the pump that is non aerated and the added volume allows the oil time to cool. Since it is belt driven at approximately 50-70% crank speed the pump is able to fill more completely than the factory crank mounted pump turning at full RPM,s. The scavenge side creates crankcase vacuum which is always good and the pressure is adjustable with a screw which is nice with aluminum rods and loose bearings if you plan to spray that much. If you are spending that much on the engine I wouldn't stop at the oiling system.
As mentioned an accusump would work in a Drag application, but wouldn't have the other benefits. Spraying that much with wide ring gaps you will need some kind of vacuum pump anyhow.

Regardless, with the Jesel belt drive, I don't think you have much of a choice. Unless the design has changed, the original passage from the pump to the main galley will get machined off, so if you do a wet sump, it wont be with a traditional pump and it will be about as custom and costly as a dry sump.

KCS is right about the JESEL belt drive requiring an external pump. I blew right past that reading your original post
