This is unbelievable ---- my local machine shop knew that I was restoring a numbers matching 1968 Camaro R/S with the original 327 motor, but when he decked the block, he "erased" the numbers and stamped his invoice number in its place! I am obviously unhappy!!! Might any of you have any suggestions as to how to fix this fiasco? Thanks, John

A restamp is going to call it out as a fake a lot faster than no stamp even when it is the born with block for the car...[/QUOTE
Before you edited that post today, the quote tag (still missing the ] at the end to fix it) was all the post had.
I hear about this more than I like to. Just had a guy email me to say that his local machine shop decked his original 302 engine deck and numbers without a second thought. There were a couple of cases where customers had sued the machine shop for negligence and won! Decking a block is not part of any std procedure for engine rebuilds........
I suspect this is partly why we stay busy with engine rebuilds and restorations.

But it is a necessary and common practice for many reasons. Blocks may need to be resurfaced to restore flatness or to improve the surface finish, or milled to change the deck height or to square the deck. Another very common practice is to zero deck a block. Any way you look at it, decking takes place in machine shops all across the country and most times numbers are not important because the block is not going back in the car it started life in!
I've talked with many machinists in many different shops about the subject because it comes up here a lot and the typical answer is the milling machine does not have a setting that allows for it to automatically not mill part of the surface. It requires taking special measures to stop the machine before it hits the pad so the customer needs to communicate and stress to the shop the desire to save the pad area...
Dennis...
And if machine shop operators have not figured this out yet, it is time they did. One court case per shop might be required though.
I agree with Jerry. It is NOT part of the standard rebuild procedure. It is a way for the machine shop to make more money though. Most blocks do NOT need to be decked for a standard rebuild.
BUT it can be done. Blocks can be decked without removing the stamped information.

Why are you quoting me out of context? You left out this important part of what I said...
Thus I didn't elude to the machinists not knowing how or it not being possible!
In the real world, numbers matching born with engine cars are few and far between. I bet most production shops (not Jerry M Camaro Guru's type shops) will do 100 blocks for every one that the numbers on the pad are an issue. I also bet 90% of engine shop rebuilds are decked to square the head surface with the cl of the crank as a routine practice! It may not be required but it's done because the builder wants to put out a quality product.
Dennis - sorry if you took my comments the wrong way. No harm meant. I apologize.
But I will stand by what I said. For the engines I have rebuilt or helped others rebuild since the mid 70s (big block, small block, dirt track, drag race, street cars, trucks) NONE of those blocks were decked. Even with 400 small blocks running 14 to 1 compression.

I wasn't questioning if decking a block is necessary or not so you standing by what you said is not at issue. You quoted me out of context and called me out by name as if I said it was not possible to deck a block and save the pad stamp which is not what I said! I accept your apology so let's move on.
I think we can all agree it is a sad thing when a block gets decked and looses it's pad stamp when it is the born with engine for the car it's going in.
