Bought an engine that was pulled out of a Jeep. Owner said it's a 250 but I can't verify the numbers.
The number above the starter is CON2. The number at the dipstick is B271, and the far right serial number is 473483 with a large GM cast below that and the number 10 cast below the GM.
I can't find these numbers anywhere.
Any help would be appreciated.


If the dash ain't steel, it ain't real!
