Recently picked up an 86 M1009 blazer that has a small block in it. What engine is in this thing? Attached are pictures of the numbers on the front pad and behind the drivers side head. Front pad is VM2328O0 and rear is 14016379

You'll want to sign up on SteelSoldiers.com, if you're not already. There are a lot of CUCV owners there (myself included). If it's a stock engine, it will be the 6.2L diesel.

If thats the original engine in that truck, its a 6.2 Detroit diesel (Not to be confused with the 5.7 Oldsmobile diesel). If its has been swapped with a gas engine or a different diesel, someone here can probably tell you what it is, if we get a picture of the whole engine bay.

Most likely a 5.7L (350) gas.
