Panic and Don1450, thanks for the replies, does anyone know if the later 239 will bolt in?
'52 Hollander interchange shows 3 different numbers and three different date ranges (heads vs. blocks):
Years.......Displacement.......Hollander Head#...Years Block #
1935-36.......208........................255.........35-36......10
1937-40.......222.7......................332.........37-48.....194
1941-51.......239.2......................363.........49-51.....211
Heads apparently all interchange (Hollander Note on 255: Fit #332 by drilling hole for heat indicator; Note on 363: bolt holes line up with 332 and gaskets fit).
So if your head is good you could use it on a later block. I don't know the differences between the three blocks - Hollander provides no interchange notes - so if the motor mounting arrangement changed you may need more from the donor car then just the block. But if the owner has gone v-thingie they won't need the frame mounts anyway . . .
