My big Block 396

hey! A couple of months I did some trade work with my friend,Me and my dad made him a scoop and put it on his hood, And he gave me a 396 big block. It had everything a engine would need except for a carb. I pulled off the valve covers and and saw tha there were bracket of some sort that were supporting the push rods. Then I saw that the holes that the oil drips out of were made bigger. I then pulled of the head And then I saw that the piston was a .040 popup. Thats is as far as I have gone as far as taking it apart. What I want to know is should I expect this to be a well performing engine with what I have found so far And How should I go about taking Apart the rest or should I even continue to take it apart

The reason I started to take it apart was because I wanted to see how clean all the parts were because I thought the engine had never had a rebuilt before and thanks for setting me clear on the guide plates

So when I take off the oil pan what am I supposed to be looking for. Hey streets i emailed you by mistake

when you pull the oil pan you will see rods and rod caps, that and mains and main caps. pull the #1 rod cap and the #4 rod cap and see what the bearings look like and let us know.
