new truck
Hey everybody, i bought a new truck to me today. Its an 84 f-250 2x4 diesel 4spd. i originally bought the truck to take the bed side off. i got the truck for 340.00 of of ebay. When i got the truck home today i started looking and it has a new rear end, trans, and i think the motor is fairly new is there anyway i can figure out if the motor has been changed. I am going to throw some batteries in it and see if i can't get it running the guy i bought it from didn't know much about it other than it was a truck.

Ensure the batteries are 850 CCA or better....... starter burnouts for less.
Check the serial/block casting numbers........
6.9L Old Style Block
Block Casting Number:
On left side of block (beneath oil cooler) 1805440C1
Note: Some 440 blocks are truly new style and must be visually inspected by raised donut around the block heater, frost plug (right rear). Old style below serial number 173828.
Visual Identification: *No counter bored area for block heater
*No defined area on side of block for dip stick
*Thickness of cast iron around block heater 3/8" (.375")
Head Bolts: *7/16, 12 point socket is used to torque head bolts
*Block tapped with 7/16-14 for head bolts
6.9L New Style Block
Block Casting Number: 1807996C1 Note: Some new style blocks have casting
number 440. Above serial number 173828.
Visual Identification: *Has counterbored area for block heater
*Very defined relief area cast in side of block for dip stick tube.
*Thickness of cast iron around block heater 15/32" (.470")
*Latest style (not all new style 6.9) has ribs around head bolts, rear two on left side go from head gasket surface to pan rail - same as 7.3
Head Bolts: *Same as old style 6.9
Also check the serial number of the block....... just behind the timing gear/oil filler cover drivers side (USA) on top of block flat spot.
According to the update I have the updated casting was implemented starting with block number 173828 (which translates to roughly halfway through the '85 model year).
