351 head casting numbers
I have a 1969 Bronco with a 351 that has the following head casting numbers/letters: 4B20; X; WCP; and the numbers 1-9-7-6-3 in a circle with a raised dot above them. It also has a double timing chain.
Can anyone interpret these numbers and why a double timing chain/ Thank you.
