Mike, your asking for trouble!! Big time. Machine measured that block in 5 minutes, and tell how much it needs to be bore. Doubt very much you could hone .010 and still use sane pistons, the can also hot tank that block, or would ever procedure to use to clean. I would never attempt sand blasting a block. Do yourself a big favor and take to a machine shop. The problem is you can read all you want, but sometimes that can get you in big trouble especially if you are inexperienced. Two minutes with a dial bore gage, which will also measure for cylinder wall taper.

Yes you can assemble it yourself that would be a big savings. I can tell you from experience your asking for trouble big time the way your going about this. I’m sincerely trying to help you.

Like I said, I am talking out loud, this weekend I will measure, so I at least learn how to build a motor, I promise I will make the correct decisions and follow your protocol.

What I’m saying is you will learn more by taking it a machine shop, and having him check the bore with a dial bore gage. In front of you, dial bore gage is the most accurate way to check it. Unless you have one, your wasting your time in what ever method you plan on using it to Measure the block cylinders. The ridge is not an issue, it will definitely need boring. Once you follow that procedure you will learn a ton.

So yeah take the block and at least one piston. I will bet money that you will never be able to just hone that block and just re-ring. By the looks of what you have that’s exactly what someone has already done.

[Gach]

What I’m saying is regardless of what the cylinder bores are, I’d be measuring those pistons also to make sure they haven’t collapsed. But if the cylinder bores are bad, you won’t need to, because then you’ll know you need new pistons. In other words what ever method you planned on using to Measure cylinders means nothing. If in your mind you think you can get away with just honing with out making sure those piston skirts haven’t collapse from excessive wear. See what I mean its like opening a whole can of warms.

I probably have about $50,000 in tools (If I were to insure them) from buying them and finding them and fixing them all my life. I bought a Mac toolbox many years ago from a mechanic that when his father died, he needed the money, full of all the automotive tools, that his father used to make a living. So, I will get an idea of what the Machinist is doing, and I will be able to compare his results to mine.

Call it practice, this way I get hands on feeling. After all, what is the reason of me studying, if I don't use my measuring equipment for the first time. Most of these guys have other jobs going and I will not be allowed to watch him anyway. I will drop off the Parts and speak to him on the phone. Once he tells me what the condition my parts are in, then I will see how deep I need to reach into the pocket.

So, I won't pull freeze plugs or oil plugs from the Block, and I won't sand blast it or pressure clean either. I will bump the sharp edges and remove the excess cast flashing, in the areas that need it. Then during the week, I will take the job to a qualified Machinist, that I shop for this weekend, while Lou preps the Block.

By my measuring things first, what the results are, you will know before it even goes to the machine shop, now you will know what to expect to hear from the machinist, see the method behind my reasoning. All it cost me is my time and measuring won't hurt anything, remember the old adage, measure twice cut once. In addition, you are speculating that this Block needs Boring and that is a Challange for me, because it looks too good in reality, and I am the only one that can say that.

Back in post 159 shows me how to measure for the Piston collapse.

50,000 worth of tools…Mike do you have a dial bore gage?

I have the "T" looking spring loaded device that inserts down into the cyl., if that is what you mean, plus many different size calipers etc...to measure that length.

Not to mention, I have already, in several places, attached a page depicting the measured Piston cyl. diameter in three places per cylinder, when the engine was in the vehicle, have you seen that? I can repost that, so you have an idea. right now.

[Gach]

T looking thing is called snap gage. Thats a rough idea. A dial bore is some thing you move up and down the cylinder thats the best way I can describe it Machinist use when boring or hone a block. Most stock pistons ( just as example) lets say they require .005 thousandths piston to wall clearance.

So the question is what did you come up with for piston to wall clearance. Then you have to take into account what its going to need to clear up and get ride of that ridge. Which more then likely cause the broken rings. And yes if you call machine shop and say I want to bring in my block and have you check the bores for me, and see if I can just re-ring it, with the emphasis that you don’t wanna leave the block you just want to check it. Done it what quite a few times.
