Hey guys we have concluded a couple things in regards to your oiling system. For the pans to be deepened the oil pick up would have to be as well, as we dont see this as a problem, we think that the pan would be very close to the ground on some of your cars which could lead to a damaged pan and there for it would not work. So we have designed a device that will help with the oiling system in a different way.
First is a oil modifier. This is a device that will bolt to the bottom end of the motor and helps with oil sticking to the crankshaft under high RPM. Under high rpm the oil sticks to the crank shaft and then you loose oil for the pump to pick up, this can run the pump dry and destroy the motor.
Edit*
We are also looking into modified pans for the additional bungs. We will probably buy new pans, make the modifications and then ship. Ill check into some vendors such as Greg for some pricing on pans.
Let me know what you think of these devices and we would need someone to test them out.
We will be offering items produced by Crank-Scrapers. With the help of Kevin we are able to sell these to you guys for a 10% discount off his website pricing. We may even be able to do better with a group buy. Look here for more infor in regards to what we will be offering.
