M coded engines

[Kurt G.]

I have a very good friend that is having a hard time getting on the board at work. He is looking for someone who has an old copy of the Restorer, specifically volumn 27, number 4 from the spring of 2001 that has an article about the engines in it. He has one in his 1970 that he is restoring, and would like to get a copy of that Restorer. If anyone has one, or knows where it can be found, please reply back to me with your information and I'll pass it on. He is member 39471.

Thanks in advance.

Re: M coded engines

Kurt, I have my copy. I can scan or fax to you. It's just 2 pages.

I looked for that issue for about a year and a half, and finally found it on Ebay. I had to buy a series of issues (28, spanning appx. 7 years) to get that particular copy. That was OK because there are a lot of good articles in the other issues. If you want an original, keep an eye on the Driveline "for sale" adds as well as Ebay.

Why don't you pick up a copy of the CD with the Restorer articles on disk from the NCRS store? That way you'll have it stored electronically and can print it as often as you like.

Does your friend have an "M" code engine block in his 'vette? If so, please tell us about it.

Thanks.

Re: M coded engines

Ken, Yes, his car has an M coded engine. We're thinking it is M45 and are trying to verify that. I haven't actually looked at the engine too closely, but plan to. I've got photos, but they aren't the best quality. As soon as I have more information, or he can remember his password I'll have him post about the engine/car.

He is looking for an original hard copy of the Restorer that features the engine information, just for his documentation and authentication. He's gotten a lot of information from another member about the engines,but just wants a bit more if he can find it. I've also suggested the CD version of the magazine to him. We'll see.

Anyway, if anyone else out there has an original copy they are willing to part with, let me know.

Re: M coded engines

The numbers following the letter M are a curiosity, but at this time no one is quite sure what they mean -- and last I visited the Saginaw Foundry I didn't get the impression there was much hope of finding any information on the meaning of those numbers. Given the current state of affairs I doubt anything has changed, nor would I expect any joy in the future.


I may be able to provide a "hard" copy after a fashion. I still have (last I checked) the electronic version of that issue, and can print the story. It is not the same as a complete issue though. So you will have to define the term "hard copy" in a little more detail.

If he wants an actual copy of that entire issue, there are several members who deal in old copies of The Restorer. I can PM him if he ever figures out how to rejoin us. Contacting one of the administrators -- through the "contact us" button at the bottom of the front page may be his best move.

Re: M coded engines

Here's the info on "M"-coded blocks from Saginaw from four years ago.

Kurt,

Attached is the first page of the document that John posted. Also attached is a picture of the block casting date from my "M" code LT1 block.

As for the "M" code engine blocks, has anyone been keeping up to date information on this topic? It appears that more owners are reporting "M" code blocks than were referenced in Gene's article, and I was wondering if anyone is tracking this anomaly.

Thanks.

Re: M coded engines

Is anyone tracking the M coded engines? I have a 1972 with an 'M4' coded block (See attached).

Re: M coded engines

I started a list back when I was NTL, and I believe that is substantially what is in Gene's article as of the time the article appeared. If you guys want to send me updates I will be glad to add to it. I believe I have only one case in addition to what is listed in the article. For a long time no one else was declaring they had an M coded block.

Re: M coded engines

I had an "M" code 1969 L46 ... Pretty cool to see others out there. Let's see some more!
