Title goes with Frame or Engine?

[jw hash]

the title should go with the chassis. the title says what the body is on that chassis. here i bought a 31 A with a 29 motor in it. years ago in this state if you change the motor you would go to the DMV and they would change the number on the title to match the motor number, I lifted the body and took the car to the DMV and had them change the vin number on the title back to the chassis number. I had installed a diamond block with no number on it.
