He's talking about Al Gorleone.

Look at this.

x2 on the POR 15.  If you can't see it, that's the best way to stop rust permanently.

Reminds me of the people I talked to over the years when I wanted to buy a car that had sitting somewhere.  I'd ask if the car was for sale.  They would say no. I would ask what are you going to do with it.  Well, I'm going to restore it or fix it up.  I would say.  I've done that a number of times.  By the time you get around to it, it will be worthless.  I have been proven right in every circumstance. I needed a parts car for my 50 Buick and this guy said he was going to restore it with his son.  Watched it rot into the ground literally.  Tried to buy a Porsche 914 and watched as it rotted into the ground.  Dreams...........

Have you looked at the AIM?

That first one is bad but that CL one for 20K will disappear into thin air before anyone pays that much.  Insane.

Like I said, the guy who did the job could have done all the above wrong, I just don't know for sure. All I did know at the time is I didn't remember seeing any cracked bosses when I took them off to be done, but all is well with them now.

surprised to believe a dull tap caused that much heat to cause cracking or the cause was tapping too fast, but I've been surprised before.
Now, I do not know anyone who rebuilds those mouse motors with that weak link still intact, i.e. pressed in studs. You stated a balance issue but not sure how bad that was and how you found out or the crank was not machined properly, are you referring to the past engine build where you ran it for 4 years or recently they machined it incorrectly. What was wrong with the crank? Now I'm not picking as you sound just like me some years past. 

The machine shop I normally use is one of the best, but he was closed for a few weeks and I couldn't get the heads to him in time, so I went with the guy who put the engine back together after checking it out 4 or 5 years ago.  I have since heard that he's had many issues with doing bad jobs.

I stayed with the pressed in studs, originally, because I never planned to take it over 6k.  When the throttle stuck and I had to push in the clutch, I watched in horror as the tach went to 8500.

The engine always seemed to shake and not feel very smooth and I suspected it hadn't been balanced. The only way I found out about the balance issue was because when I found the head to be cracked I knew it would be a while before I would be able to get them back on.  Since it was approaching winter I decided to tear the engine down and check out if everything was ok because of the rep with the guy that did it.  The good machinist is the one that found all the problems.  He said it was the worst out of balance he had ever seen.  Of course with hindsight, if I had just gone to him in the beginning, all I would have had to do was put the screw in studs in the head.  He said he uses a new tap on every job and said if it gets too hot while tapping, it can crack the bosses. 

He showed me the crank and it had rub marks on the sides of the counter weights and the rod journals were rough around the inside edges.  He said it was welded (badly) and the machining process was sloppy and gouged the inside of the journals which is why my bearings were grooved.  It also was wearing unevenly.  So the combination of the bad machine work and the out of balance really made the engine shake at idle and above 5k.

Everything is good to go now, but I'm having a hard time getting all the parts needed from one place like Summit.

My best guess is the guy's son did the work and either ran the tap too fast or used a dull one and the heat build up cracked it.  I pulled them out but didn't notice the cracks at that time. 

Thanks for the recommendations and I'll see if I can get this sorted out and order some parts today.

Well, Summit has their kit for $88.  Not sure if that's good or not.  Rings, gaskets and bearings.
27  Camaro Research Group Discussion / Restoration / Re: 68 Z engine parts on: March 13, 2014, 10:14:12 PM
What is in a re-ring kit?  All I need is the rings and bearings.  I already have a complete gasket set.

I tried to tap the holes myself with a guide specifically made for the threaded studs that look stock.  I couldn't keep it straight so I quit and had a machine shop do it and then noticed that a couple of bosses were cracked.  I couldn't prove that the machine shop did it as I didn't pay that much attention to them when I took them in.  Had to get the heads welded and everything is good on them now.  That's what made my mind up to do the tear down as by the time I got the heads fixed driving season was over.  

In regards to your suggestion of the Clevite 77's.  Are they that much better than the Sealed Power?  I appreciate your input.  It's just that that's what I had in it and came recommended from the shop that probably cracked my heads.  May say volumes about them.  Also, checking Summit they only ones that seem to be iron are Mahle.  Thoughts?
29  Camaro Research Group Discussion / Restoration / 68 Z engine parts on: March 13, 2014, 08:19:41 PM
OK here's my situation:  I have a CE 302 that was rebuilt that came with my car when I purchased it.  I took it to a machine shop to disassemble and check to make sure it was good to go.  I got it back and ran it it for about 4 years.  The only thing I didn't do was check the balance.  Big problem.  Then about a year and a a half ago I pulled some rocker arm studs out when my throttle got stuck to the floor and I had to push the clutch in to get stopped.  So I decided to tear it down and get it balanced as it was winter and I wouldn't be driving anyway.  That was November 2012.  Long story short, I just got my parts back and had to use my spare crank as the one that was in it wasn't properly machined.  So now I need to get new bearings and rings.  So:

What kind and style, brand are you people using or could suggest?  I have gone on Summit but there seem to not be a lot of choices.  My original bearings were Federal Mogul which seem to have been replaced by Sealed Power.  I'm not going to race this thing, but I don't want it to fall apart either.  Middle of the road Sealed Power A series rod bearings?  Clevite?

The other question is rings.  I have the TRW 2210A's.  I was told that the rings that were on them are .062 top and bottom and .124 oil rings.  What style-brand do you suggest?  I was also told to use iron ductile rather than moly because of seating issues.

Input on this would be greatly appreciated as I want to drive my car again someday.

That's what I used on my headers.  I had to use a washer or two behind the bracket to get the alternator pulley in line with the others.
