I never have seen the inside of a 2v oil pan, but I believe you.
Oiling is something we keep coming back to because I have not found a satisfactory solution for us yet.
The more complex solutions pretty much go hand in hand with a blower setup, and that includes oil seperator devices.
For a simple NA car, a simple solution seems best, Maybe Grog is onto something with a simple physical scraper inside the timing cover to sweep off the chains.
The existing oil pan is fine, and the drainback extension kit will help I think. If I come up with anything, I will share it.
I think we pretty much covered the gear ratio and setup subjects. OIling can be revisited.
As we prepare the car for the mission, we will seek help from you along the way.
