Where are the block numbers located for a 67 ford inline 6. I don't know the size engine other than it is an inline 6. This engine was put in an 83 f150, I don't know how to id the engine as far as cubic inch. thanks

 

It is either a 240 or a 300 as they had both in 67.

 

Look at the crank pulley. If it has three grooves, it's a 300. Two groves, it's a 240.

 

The vehicle belongs to my son, he called me after I posted. He found this id number on the block-- OSTE-6015-AA. The closest thing I could find, was a D5TE-6015-AA, which I believe refers to a 300 ci.

I did pass along the information from the replies. thanks
