Hey everyone,

I have a couple questions that I am hoping all you Ford guru's can help me with. I recently bought a 70 XL from the original owner who claims that the engine has never been replace but I was questioned by someone who said they looked at it years ago and came to the conclusion that for whatever reason it was not original to the car. I have yet to hear back why he says this as of yet.

I checked the engine tage which reads..(at least I think it reads)

429 70 6
9-M K813

According to the internet the 429 is correct, the 70 is the model year (correct), the 6 is I dont know, the 9-M is where I get confused. 9 means it was built is 1969 and the M is for the month (confused on that too). The K813 is I believe correct as well.

Was it common practice to put 69 motors in 70 models? Am I missing something here? These numbers look to be right (even with my bad eyesight)?

Any help would be appreciated.

Cheers!

The 1970 vehicles went on sale in September of 69, so there is a very good chance it has parts made in 1969, even if it was assembled in 1970. 9-M would be December 69, well into MY1970 production. The VIN number and Warranty Tag info should give you production date info for your car.
