One unique requirement of this engine is that it needs to be a front sump for the 240sx configuration. Finding a front sump oil pan that is decent is hard to find. It was only offered in the mid 60s Nova IIs and a lot of guys do a rear sump conversion. I found this moderately priced 7 qt pan online. I did some preliminary measurement last night and it looks like I will need to box about 2 inches in and about 1 inch up on the front of the pan to clear the front sway bar. After it is done there should be atleast 6- 6.5 qt capacity. The rear looks like it will be OK for fitment, but who knows until you get it in there!
