I tried to post this spread sheet I made yesterday but the posting process scrambled it. So here it is as a jpeg (I tried 4 times to make the size correct but couldn't get to go.. help!).

The figures are for the last and biggest version of each engine type and the years are “car only”; nearly all continued much longer in trucks and industrial power plants. Also, the book (see earlier post) lists block length, but the early engines included the bell housing at the back and had an extended nose due to the chain drive generator, so they measure really long.
Check the cylinder spacing on the “Big Six”…lots of metal there!
