400 Engine Serial Number Location
Hello all!
Can anyone tell me the location of the engine serial number (the stamped in # not the cast in #) on a 1971 400 motor. Is it at the back of the motor??
Thanks,
Allan

351C, 351M, or 400 Ford Engine - What is the difference? - FordMuscle
This has a lot of info on the 400. I just learned that the factory retarded the timing for gas mileage. I am purchasing a aftermarket chain and possibly a mild cam. Hope that the piece will help you.
I just noticed that this was started a couple days ago Oh Well someone can use the info besides it is still early and I am buzzed with caffeine

Unlike the GM camp Ford only put partial serial numbers on a few engines, Boss 302 and Boss 429 come to mind.
Most of the engines only had the standard casting numbers on the engine components.
Ford did put a little aluminum tag on engines with some info on it, it was usually bolted on with the coil bracket, a lot of times when the coil was replaced that little tag disappeared.

http://grantorinosport.com/BubbaF250/ has a lot of info on the 400.
Ford never put a retarded cam timing 400 in a pickup. What you just learned is wrong. See attachment.

Somewhere around 67or 68 maybe a little later Ford started stamping a partial VIN # on the back of the block just below the cylinder head on the drivers side, they also stamped it on the top of the transmissions. It's not really a serial number but you can determine if the engine and transmission are original vehicle they are in.

Partial serial numbers would be on the coil bracket tag
Ford has always used a coil bracket tag
I can tell you, the correct coil tag for a Boss 302 will cost you about a thousand bucks if original
