55 F100 engine ID

[tommyleea]

Running into conflicting info on available engines. In the Identify your ford article, it states that a V in the VIN for 55 is a 239 engine, and a V in the VIN of a 56 is a 272. In the Ford Y Block book, it leads you to believe that the 239 ended in 54, and the 272 took its place in 55. Here are some numbers and info on my engine.

Intake..ECG9425H (272)

Timing Cover...DIF EBV6059 (239)

Exhaust Manifold...DIF ECE6430 B

Block by distributor...ECO..which is not listed..picture included..

Rear sump oil pan..

Have not found any numbers on the heads yet..

Can you help me figure it out? Thanks
