My first rebuild

You can also use heat on the A arm to expand the hole, just not too hot, rubber burns and you'll smoke yourself out! Ask me how I know

I realize I forgot something in the pictures, the easiest way to get the outer shell out is to simply put your wide blade on the air hammer and crush the shell into center shell (if needed, do it on two sides). But first, get that center bushing loose first. The outside is easy, but if it's knocked loose first, the inside may end up so bad that you'll have to melt the rubber out, remove the outer shell, then cut a slot into the center shell to knock it apart (yeah, I know this one well)...
to get the center to move, put the bolt into the cross shaft where it's about flush with the a-arm, stand the a-arm on its end (and on the bolt), then put your pointy bit in your air hammer and knock on the center sleeve with the pointy bit until it moves. Then do the crush, then get your pointy bit back on, remove the center bolt, then knock the center sleeve out.

The best I could understand was th 4&31 simply meant since the bores are already .30 over bore they had only worn 1 thousands more and after the home should be 2 1000 thousands or less so they don't need bored.
I am all about saving money but thought letting him do those smaller tasks may be best.

The machine shop is gonna want your new pistons and the type of rings your using to finish the block. I used to sit down with them and call summit, Jegs or PAW from their office with everything written down. Sometimes you'll get a chose, like gap less rings over standard moly or head gasket thickness and its always good to yell across the shop to get the right answer!
Not sure how well you know your machinist, but it sounds like he's being a good businessman and lobbying to build you a shortblock, i.e.,hone the bores, fit the rings, polish the crank, and do all the assembly work himself. For me, that's a Saturday in my home garage. For him, maybe $600(?) Good business for him, not so much for you. You can buy a honer at Autozone, Pep boys, etc. for around $20 that will put a pattern on the walls and we can all walk you through how to use it. Fit the rings using a feeler gage and some small half-round or jeweler's files. Polish the crank using emery cloth, etc.
Some here may say I'm nuts for doing things this way; these weren't race motors I was building, but one went 50,000 miles in my '72 C20 truck, and was still strong when I pulled it out and sold it to a friend for $400. It sounds to me like you don't have a piggy bank full of hundreds laying around, and as long as you have a solid block, eight good pistons that fit within tolerances, put a decent-looking pattern on the walls, and can put this thing together with correct ring end gaps it will run forever if you don't abuse it. As I mentioned earlier, if you beat on this kind of rebuild you're asking for trouble, but if you just want a reliable, leak-free runner the there's nothing wrong with doing it this way.
Bottom line here, the GM line assemblers weren't rocket scientists, and you don't need to be either. Lord knows I'm not!
Gotta go....more to come

This is his first engine, and putting one together correctly is hard enough when you've never seen it done (meaning never did it with your own hands on your own motor) first.
But I agree that putting a motor together on a top ramen budget should be required learning for anyone who calls themselves a hotrodder. I've emery clothed bearings, cranks, cams, used a paper bag for a head gasket, even touched up valves with a file and a drill motor - but I'm glad I didn't start there.... my first motor was a disaster because the machine shop messed up - so they fixed it (without much whining either, surprisingly)....
Confused!
Hey I was looking under my car tonight to see what the kind of shape the floor pans are actually in...Ugh! They look and feel like fiberglass or plastic...

Is that right? I saw a couple of threads and others looked like steel... What say you?

I must admit that all these years have taught me a little about what I could and couldn't get away with (Paper Bag head gaskets???WTF????), and Fatcat, if you're not comfortable with my admonitions by all means RUN THE OTHER WAY AS FAST AS YOU CAN!!!
If, on the other hand, you are reasonably confident that you can do this, I am quite confident that we can communicate to you the necessary steps to walk you through this thing successfully...I say be brave, grasshopper...

Hey Birdsmith! I may be too confident!
I really have learned a ton from you guys and I am going to call the machinest tomorrow and see if he started cleaning etc. I told him to today so if he has I am going to just have him stop at a point and pick it up. I only gave him $150 budget to start with to clean the block, hone and polish. The good thing is at least I know his work from the shop I work at.Hey did you see the fiberglass floorboard issue I have going on too???
Man this has me stressed out!
