i pulled some numbers off my th400 today, just wondering what its out of.
Heres the numbers i found, there were a few others, its out of the car so i can get the other numbers later if there needed
8624486
CA-69-70217 426
190042073

It is out of a 69 fullsize chevy. In the stamped vin, the first 0 is probably a D or a U. For Doraville, GA or Lordstown, OH. Can you check that code in the vin?
Looks like the engine was a 350.
