machine shop cant align bore block

[Falcon67]

That's just - sad.  Sounds like your next machine shop stop will make for a better day.

Thanks for the kind thought's Chriss.
I just finished putting the block on the engine stand and found out what they did.
It didn't look like they touched the caps or anything else except they tried to remove the block drain plugs.
It looks like they drilled though them and then used vice gripes to try to remove them.
I was saving that job for when I was ready to prep and clean the block, so now I have to drill out their mistake and it looks like I will have to tap for a bigger plug.
The funny thing is this is a highly regarded race shop here in Okla.
I used them in the 80's to do all the work on my outlaw late model and sprint cars and when the father was alive we all ways got quality work from them.
I guess this is what happens when the son takes over the shop.

WTF  Hope you find a shop where the use their head
for more than hang a hat on

Wow Greg hopefully your next stop will be competent and trustworthy and get the job done. Just let me know if the caps are the issue.

Good ideal but I prefer C4 or my M-14.

You old guys are grumpy and have hemorrhoids.  At 53 I am starting to feel your pain. At least the grumpy "Get Off My Lawn Millenials!" attitude.

They didn't get that right either?  Dang, that's basic stuff - I have to do that with every block I start with LOL, not lol.

After checking the mains yesterday I don't think there is any thing wrong with them.
I was just going with the shop told me on the phone.
There is all most no parting difference in them. I will get my bore gauge out and check them later today.
Oh well I guess I need the practice working on these engines.
I don't know why they were removing the drain plugs unless they were using them to take measurements off them for the align bore.
I am not a machinist just a shade tree  mechanic but if I was a little younger I would enroll in a school and try to learn the basic's at least.

Drain plugs have nothing to do with align bore. I am assuming they were going to clean the block too? Is standard practice to remove all plugs etc... when cleaning a block. Heat the plug with a torch until Cherry red and it will come out. If that scares you can drill it out almost to the threads then use a tap to clear out the rest. If it was drilled off center get it close then use a DreMel to grind out the rest.

As far as the main housing bore goes there is a line bore and a line hone which are two different procedures. Usually a block is just line honed to true up all the housing bores and bring them to size. An align bore is done when you have to take more than a few thousands off. Usually only need do that when fitting new caps.

Keep in mind not everyone can do everything. A lot of shops can do a line hone, but don't have the equipment to do align bore.

If the head is still on it you can weld a nut on it and remove it with a socket.

Hi
For those interested I will post pictures of the fine work our Oklahoma premier race engine shop produces.
They were not suppose to clean the block because I haven't prepped it yet.
 I still have to grind off the casting slag and clean up the inside of the block.
I would have heated these and pulled them when I finished the block because I knew they were rusted in like all of them.. Now it looks like I will have to spend a few hours to fix this.

Here is the other side.

Here is how i do it drill a hole in a flat bar and countersunk
and weld it to the bolt/plug/whatever. let i cool for a couple of minutes
and unscrew it

[gregaba]

Heo
Thanks for the ideal.
If my methode doesn't work I will give your's a shot.

Drill it out almost to size and run a tap thru it. Holes look pretty centered.

[gregaba]

That was my plan.
Getting ready to go out and start on it.
I though I would drill it out real close and then try one of my left handed drill bits on it.
