Thanks for the response towards my question. What I am really after is how to tell by the numbers on the block will match the cars VIN or Trim tag. I have a 90% complete original 1969 Chevelle SS 396 325 HP with air L code Kansas City car paint code 71, with all of the original parchment interior minus the original engine that I just purchased and has been sitting since 1984. I was told of the whereabouts of the original engine to this car and spoke with the individual who has it. I am going to do a concours restoration on this car and would like to know how to verify that this engine is the one the car was born with. The numbers that were given to me from the machined landing on the block are T1025J0 and 19J145089. Any help would be much appreciated. Rich
