I found an old 327 long block.(FREE) I have searched for as much info as I can find but I still have a few questions on some odd things on this block.

Heres the info I have so far.
Block casting #. 3903352. 65-67 327ci 210-275hp pass car only block. 2 bolt main, SM journal crank and rods, Steel crank.

Heads. 461's with no bolt holes. No biggie.

Now on to the questions:
1. These is a "can" mounted in the lifter valley attached to the rear wall of the valley. What is this? Is this some type of early PCV?

2. There is a "plug" in the rear of the block near/next the oil pressure sending unit. It about 1 1/4 in dia.

3. This block has a "2 step oil pan" It comes down from the front seal and curves back about 7in and dips down about 2in. then back about 5in then down to the sump......It looks like a stock stamped pan.(never seen anything like it)

4. There is a "lever" mounted to the bell housing bolts on the drivers side of the block. The top of the lever looks as if it lines up with the carb but the bottom side looks as if it line up with the trans? early trans kick down for a powerglide?

I'm still searching google but I really dont know the correct name for these parts so its come to asking for help from y'all.
