• Got the Contributing Memberships stuff finally worked out and made up a thread as a sort of "How-To" to help people figure out how to participate. So if you need help figuring it out, here's the thread you need to take a look at -> http://www.corvetteflorida.com/forums/showthread.php?t=3581 Thank you, everyone! Rich Z.

C5 427 forged motor?

Man, I'm now hooked on this thread. It's like a freakin' train wreck. Good luck and I hope everyone rectifies the situation properly for you. I can't even imagine how livid you must be right now.

Yeah.... But this is nothing compared to how I will feel if this isn't resolved quickly and satisfactorily. And yeah, this entire experience is tainted for me now. I've got a gut feeling that these are all bad omens trying to tell me something.

Well, I'm going to run out to the shop today, but my heart isn't in this any longer... Maybe some good news for a change would help, but I'm not holding my breath on that one.
 
Getting anxiety from car issues is the worst. At least its not your daily. That is the thing that sucks most about mine.
 
Finally making some progress. Apparently the measurements taken by LME proved conclusively that the heads were machined incorrectly at World Products. So those defective heads are being shipping back to World Products to be replaced by new ones.

Now all I have to be concerned about (at this moment) is the fact that shipping anything this time of year is not the best time to be doing that sort of thing.

All things considered (holidays in particular), I'm not expecting to see that engine back at XtremeMotorsports until well after the first of the year.

At least World Products manned up to the problem and didn't try to slough it off as a "well within acceptable tolerances" dodge. Chris and I discussed our alternatives today before I got this news, figuring on what our next step would be in the worst case. But fortunately we won't have to go there, it appears.
 
A little G:):)D NEWS in this tunnel of darkness.
Maybe this time it'll all slide together like it's supposed to.
I've got my fingers crossed Rich.................
Andy :wavey:
 
Man! This has got to be like the male version of giving birth for you Rich. Breath, breath, don't push.:D

Maybe with increasing age I'm getting more mellow. A few years back I would have popped at least three blood vessels in my brain. Of course, had World Products flubbed the right way to handle this, that may have happened after all.

But the fat lady hasn't sung yet, folks.....

Heck, just had this thought.... I certainly do hope that the warranty period on all this stuff starts when it is installed and the car hits the road, and not when the parts were received. :nonod:
 
Carbon fiber driveshaft....Hope I posted the right pics..

Thats wierd, there was a good pic showing my car with some stuff on it and now its gone?

Interesting location for my car too.
 
Darn, I missed that part of the install. Not sure if that is when I was sick or when the garage was being put up.... :nonod:
 
Inside every older person is a younger person wondering WTF happened?

Yeah... I quit believing years ago that the old codger in the mirror looking back at me is REALLY me..... :nonod:

Well, I got word that those heads have landed at World Products and they are running them through quality control to see what went wrong. Hopefully that won't take long and those new heads will be on the way to LME pretty shortly.

The sooner the better......... I'm going to forget how to drive a stick shift.... :nonod:
 
OK, I'm beginning to lose my cool now. I'll post some emails here between Billy Mitchell Jr. of World Products and myself today so either you all can see what I am getting pissed about, or else just tell me I'm being unreasonable....

Sounds like you will be paying for a "bubba fix" on the heads instead of paying for new "correct" heads in the first place. Hell, these people are in the "HEAD" business as a profession, and "should" know that this would happen if the heads were milled. I can understand that there might be a little misalignment, but that's where the gasket comes into play. Your problem was a little more serious than just "slight misalignment". My thought would be that since you paid for new heads, get new heads........not some new heads that have been boogered up. The fix that they are proposing may work well and last the life of the heads with no problems, but I'm not familiar with head geometry, aluminum metal specifications, pro engine building or any of the other stuff that goes into a part like this, so I really can't intelligently comment on whether it will do it's job correctly until you decide to replace the heads. My gut, on the other hand, is telling me that you might be better off finding another vendor for the heads. This doesn't sound like it will be a good solution. There will ALWAYS be a nagging doubt in the back of your mind like "OK, when am I gonna have trouble with this setup", or "how many times am I gonna be able to take it to the redline before I hear a funny noise", or "how far from home will I be when the "fix of a lifetime" BREAKS"! If it DOES break, I'm pretty sure that you won't be able to stop by your local Chevy dealer to get it repaired! It will most likely have to go back to Chris to be repaired. Wanna take a guess on the cost to flatbed the C5Z from ,oh.....lets say Orlando (or farther).....to Blountstown? Even if it doesn't break, the thoughts will always be there because, in YOUR mind, the job was not done correctly. In the end, I guess that you're the only one that can YEA or NAY the fix, and you're the only one that will have to live with it. I'm not going to take one side or the other, but I might ask some other people in the head building business if they thought that this fix was acceptable and get some professional opinions. I'm sure that some of the tuners on this site would be happy to provide you with the names of some other reputable head builders that you could take your questions to. I'm sorry for all the trouble that you've had to go thru with this project, and man do I hope that it turns out OK when it's done.
Andy.
