Oddly enough we just happen to have some engines in the shop now that represent the start of the auto engine, mid century and modern day. (Model T, Jag XK120, and GM LS7).   All three of these engine share close to a 4.000" stroke (Model T and LS7 are both 4") while the Jag has a slightly longer 4.17" stroke so the c/h is about the same on all. Model T of course is a flat head while the...
