I believe the first letter/number is actually a zero, not an "O"...there should be 7 numbers before the plant letter.

So, here's the way your number breaks down.

0363508T56Z

0363508 = unit number starting with 0001001
T = Tanawanda engine plant
56 = year (1956)
Z = Regular 235 6-cylinder with a 3-speed from a passenger car

You have the 362,508th type "Z" from Tanawanda.
