10 days to 5 weeks before the car.

thanks...the date code on my motor is 9A20.....which I believe translates to jan 20 1969. my marti report shows a build date of march 27 1969. this puts the motor at 9-10 weeks before the car. could that be?

it would be highly unusual but possible . . there may be a partial vin number on it somewhere.

thanks for the info...i looked on the back of the motor but really can't make anything out....too close to the firewall. I have to get my hands on one of those cameras with the flexible neck.......

Might depend on what the motor is. 6 cyl, 302, special, etc.
