Most blocks have a 5.0 or 5.7 cast into them near the casting number. If numbers fail your investigative work you will need to pull a head and measure the bore.

Sure you wrote it down correctly?
Dont tell me you misread the last number as a 2 instead of a 7. And if you did you should be slapped for reading the head casting number
14102187...87-91...305..........1.84"/1.5" valves
