Title: Finally confirmed 'matching' number engine block :)
Post by: click on March 19, 2018, 03:17:07 PM

 Last night I received some great pics from the guy that bought our 69 RS a few years ago. He is putting in an LS1, so he pulled the original engine out. This engine is Oct 68 build in Los Angeles and did NOT have a partial VIN on the pad behind the alternator. When I owned it, I tried looking by the oil filter with mirrors and bright lights and I thought I saw numbers in the rough cast area but it was not 'proof' positive the engine was original to my car. Well my buyer Greg got some yellow chalk out and now we know this is the original engine block to an LM1  350 . The VIN is L505849  and now here are the pics of the rough cast area by the filter.  Kurt S can add this info. and pics to his records now.

Interesting, makes you wonder at what VIN did they begin this practice?

I have a pic of one less than 1000 VINs later, and it is a bit different.  I will let Kurt comment, since I am not sure.

Haven't we ascertained previously that LA was inconsistent on the location of the VIN derivative on the engine blocks (from deck pad to starter rough surface) throughout the year...  ?

Jim - could you just post one more pic, of the whole partial VIN but not so zoomed in? Makes it easier to compare.

I was under the assumption that it started on the pad similar to 68, and then at one point, went back and forth between pad, and rough cast by the filter?

Can you post a pic of the engine pad?

 I will have to contact the buyer of my car to see if he can snap a pic of the whole pad in one screen shot.

 Yes just last night he sent me a few but while the numbers were fully in one pic, the clarity was not as great as I hoped. He is going to try a different color chalk and mess with it again. :)

 Just so I keep all the numbers in one posting, here is the pad behind the alternator :

Yes resolution isn’t the greatest. Images can be up to 200 KB.
