#1 I have what I believe is a 1958 Chevrolet 235 Engine that I am contemplating an overhaul on. I see that it has hydraulic lifters? does this mean that this is a passenger car engine? I was under the impression that 1958 truck 235's had solid lifters?
#2 Can a 1955 Chevrolet 235 head be used on a 1958 engine block? I know that chevrolet changed the oil passages in the block to the head (valve train)in 1958.
Best Regards
Will

It is either a passenger car engine or a truck engine that has been retro-fitted with hydraulic lifters.
All 235 truck engines used solid/mechanical lifters.
Yes, any 18-bolt 235 head will work with your block. A 1956 and later head produces higher compression.
The oil-feed plumbing to the rocker arms changed over the years. Someone else will have to comment about what is needed for plumbing an earlier head to the later rocker arm assembly.
