The only difference is that the A-H has a 2 bolt distributor fitting whereas the A90 has one. This however is a bit of a simplification because there was a small amount of overlap with early 100 having blocks with only one fixing bolt and very late A90s having two. To make this more complicated if it were BMC Gold seal replacement engines. These could be delivered with either one bolt or two. It is possible to fit a A-H distributor to a single bolt version but the mounting plate has to be from an A90.</div><div><br clear="none"></div><div>All other 2.2 and 2.5 litre blocks have different bores so this can be measured fairly easily.
