Bob, if the index on the left is a factor of cubic capacity and revs, then the latter can't be correct unless they were tiny engines? How does the statement play with the comparison of Zeniths in Austins, for instance... are there any examples where there are similar conditions at play allowing one to just focus on choke and partially-linked jet size in the two variants? With Sevens, there don't seem to be any direct comparisons available as the cars were getting heavier and engines changing when things moved from vertical to horizontal.
