Need opinion 904 or 727

im in the process of rebuilding a blown 904 (not exploded i may add) and to be honest, for me the 904 is 'my' best option due to not loosing those few horses through rotating mass of the 727,
BUT
to build a awesome 904 costs more to get to where a 727 starts to need modifications, (does that make sense?) but the 904 will be better behind a small block in my opinion
