I have a 69 3/4 ton 2 wd. i was told it was a 327 cid/325 hp. I have not pulled the engine yet so i cant read the casting # yet. the #s i do have are on the pass. side behind the alt. engine suffix code is v113ockd partial vin in the same place is 12k545158 i can,t find it at mortec. another site came up with a engine suffix code for a350 cid 1972/1977 years. the oil filler tube is in front of the engine in the center like the early 327 s any help with the suffix and vin #s would be very apreciated thank,s big lou55.
