Help identifying gm block

[Rebel619]

Good afternoon I just a purchased a  motor that was supposedly out of a 85 g30 van. Pretty sure it's a 350 but can't make out the stamp. Can anyone help me make out the stamp? And possibly the tranny also thank you!

If you want to know more specifics, try and see if you can find the other one or two stampings.  That will indicate engine specs and possibly what type of vehicle it actually came from.

Transmission is 1988.  8LZA is 87-89 1 ton van and 1 ton pickup with 6.2 diesel.

That was quick, thanks newdude. Is that tranny the th400? I can't find anything under 8LZA.

If I'm reading the stuff right, V = Flint plant, 02 = February, 19 = 19th day. 

 

As for the "FLK", that's the suffix code and I just found a PDF for "The Complete Chevrolet V-8 Engine Code Pocket Guide 1955-1991" from a Corvette page and its awesome.   THE BOOK -  LIME_BOOK_2018.pdf

 

FLK = 1985, 350 cubic inch, 160HP, 4 barrel carb, manual transmission truck.  

 

I was also able to find the p/n for it too, 14080371, which only comes up in 1985 G van 1 ton, suffix FLK, 350 VIN digit M, M40 THM400/3L80 and NB2 Cali emissions.  So I find it interesting that the engine book shows manual, but the GM parts catalog shows it would have been an auto transmission. 

 

But more importantly, it seems to support that it came from a 1985 G van, the engine serial "14010207" checks out, as does the "FLK" stamping on the block pad.  

 

 

As for the "CF4137529", I'm getting hung up on that.  "137529" should be the last 6 of the vehicle VIN.

I found that lime book last night and was able to track the flk but did not find as much info as you did. Thanks again newdude!
