Some records also show:
block casting 3835911
with head casting 3701887
Truck 1954-55.1
Passenger 1954-55 Mech. cam
but with the 848 or 913 head
The 3701887 head was also used in 1953 passenger & truck with the 3701946 block, mech. cam.
Like Tim said, post the block date casting code, it will give you a better idea.
