Stamp Pad Disaster

Re: Stamp Pad Disaster

I was working with a shop that is well known for street rods... a completely different craft. He sent it to the machine shop he has worked with for years. There is merrit to what you suggest but as upset as I was I believe the problem was that they were in "street rod" mode and I did not do enough to protect the motor. I'm not defending them but I have to say that other than screwing up the pad, the work has been top drawer in all respects. I have checked all tolerences myself and found them to be right on. I would guess that the person who decked it did was not the owner and probably not experienced with a restoration motor. Thanks for you thoughts on this.

Re: Stamp Pad Disaster

Once again my small investment in the membership for NCRS has paid off in spades. It's great to get so many informed opinions. I'm taking the glass half full appraoch, as many of you suggested, just happy there is enough left to ID the motor as original. It will just be part of the story of the car (and a learning experience). I have posted a couple of more positive pictures. The first is of the "bolt sorting table" after the bolts came back from cadmium plating. The second is of the front brakes going back on. Thanks everyone!

Re: Stamp Pad Disaster

Jeff,
I feel your pain. I had to have my 67 L-79 rebuilt and
upon a recommendation of a well respected mechanic friend, I had the engine rebuilt by a great rebuilder but not familiar with the importance of the stamp pad. I instructed the rebuilder about that importance and he assured me that he wouldn't deck the block. Well, when I went to pick up the engine I discovered that he tumbled the block for cleaning purposes and I lost my broach marks. The pad looks pretty though!!

Re: Stamp Pad Disaster

Sorry about that. I bet it runs great though! Did the car Top Flight after this happened? 38 point deduction?

Re: Stamp Pad Disaster

The engine rebuild was after the Chapter meet judging, so it was a non-issue.

Re: Stamp Pad Disaster

I had a similar case with a correct passenger engine for a '59 which the builder decided to deck (while I did ask not to do this). This didn't only cost me points for an incorrect number sufix (D instead of DQ) but I also lost points for missing teh broach marks.

Without the broach marks the numbers aren't to be judged in the first place, correct or incorrect. If I'm correct it costed a total of 88 points (50 + 38). BTW it didn't stop me from scoring a Top Flight with the car afterall...

Rob.

Re: Stamp Pad Disaster

Leave it alone it will be OK, like mentioned above, the only thing you will do is make it worse. Find out the deck clearance and finish the rebuild to achieve max compression with the head gasket selection. Make it run strong!!

By the book it's probably the correct way to rebuild a engine anyway.

Your lucky, if I put all those bolts in my family room to sort my wife would then

Incorrect Rob. The three pad features are judged independently of each other.

Rob,

That would be incorrect. The casting number & case configuration are judged first (350 points). If correct then the casting date (175 points) is judged. If correct then the assembly stamping (25 points) and VIN derivative (25 points). The last item judged are the broach marks for a total of 38 points.

Jeff
There should not be any paint on/in the pad.
Smear a little oil on it, take the 38 and move on to more important things.
Like Ops at 25 points perline item.
Nice work on the frame.
I happy to that someone else employs the proper use of a family room for which it was intended.
