IF it had an original throttle body, it is a 94. You can check that by the casting code
on the back of the block that is just to the driver's side of the distributor. Last digit
will be a 3 or 4 on the 4 digit code (first digit is a letter indicating month, second and
third are day, and last is year digit)

The best numbers I can come up with are: large numbers, 57LGSGI and small numbers next to dist. 280 and a little lower L106 but these numbers are very hard to make out so I am not sure if that is correct.
These numbers are in addition to the casting number 14093638.
