reasearch on hemi blocks

[69 500]

 trying to do research on the Julian calander date on hemi blocks, but need your help. if you have the following information and are willing to help  all the info will posted as it becomes available .
the info I am asking for is as follows.
1. model and year of your car.
2. spd of vechicle.
3. picture, of casting date on block, vin stamping on block, and the Julian calendar date and engine serial #.
    the purpose of this research is to help identify when cars where actually built. cars such as the charger 500's had a quite a few SPD's of 907, some with Julian dates in August and others in October , but share the same SPD . pictures will actually be needed to verify all information. so if we can collect enough data we will be able get closer to the actual date the car came off the assembly line. any help will be appreciated. email info to littledetroitrestorations@hotmail.com. thank you mike
