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.

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.

So, the question is: "what did you come up with for piston to wall clearance? Then you have to take into account what it's going to need to clear up and get rid of that ridge.

Well, since you put it that way, I need to have them turn the Crank and match the Crank and Rod Bearings. They need to magnaflux the block and check the Rods.

Let me send you all the information now and you look at what I have and I will continue to get the rest of my measurements the way that I have learned recently. You will have enough information from what I send you until then, OK, fair enough. Then we will discuss the rest.
