Northstar Engines and System Technical Discussion Discussion, Will I suck her dry if.... in Cadillac Engine Discussion; I have modified my oil pan to start half way back. I took out the flywheel/Rear part of the oilpan ...
You should be okay for drainback. The extra volume of oil in the pan is not for drainback protection it's for cornering capability. As long as the pan was modified so that the oil drainback slots are open on the sides I would expect the system to work fine. Hard to say positively without some pictures and/or testing but generally speaking what you describe shouldn't cause the oil pump to suck air. You will lose some horsepower due to the restrictive windage situation with the shorter portion of the pan but it wont be a lot. Make sure the oil level stays the same when you refill it the first time as overfilling the lesser volume pan to the point that the oil level hits the crank will cause severe aeration of the oil, etcetera.

Re: Will I suck her dry if....
i had to cut the oil level dipstick for it to read two slashes lower than the full mark. Which actually works out cause then Ill just lever the motor and fill the oil and then ill be within reason of the stock "full" mark. I cut 1.25 inches of the splash shield and the sump tube back.. thats the clearance i needed for the rack. ill post pics tomorrow... worked 14 hours today im off to bed.. Hope this makes sense
