A 1953 15 bolt head will not bolt to a 1954 18 bolt block
"0030392F54Y - engine serial number (pressed into the block)"
F = Flint MI engine plant
54 = 1954
Y = car 235 with RPO 313 (Powerglide 2-speed automatic transmission)
This engine would have had hydraulic lifters (no truck engines came with hydraulic lifters).
"don't have the block number with me
3701887-gm7 head"
3701887 = 1953 truck low-pressure 235 head
b2-887-066-570 ??? where did you find that code?
Find a post the head/block casting codes, and date casting codes.With the date casting codes, we can better date the engine.
How many bolts/nuts/screw are used to attach the valve cover to the block?
