Hi All
Jim Sewell just raised and interesting point on
http://www.mapleleafup.org/forums/sh...d=1#post111294 "The 216 engine that was used in the chev blitz was made in Canada from 1937 to 1945 and this can be identified by having a single hole from the water-pump to the block and having dome top pistons .
This same engine was produced in the USA from 1937 until 1940/41"
It illustrates the use of master catalog as well as the cross over books such as Hollanders Interchange Manuals (these I believe are now available on CD).
Jim's point about changes in piston design is illustrated in the scans of the parts book page attached. The first two are from the Canadian Chev Master Parts book and the third is from a US Master Parts book note that the US one list the prices in 1967.
