   you really need to upgrade to the 727. 
that 904 ain't up to the weight of the car or any more torque...
i think there are several other things your gonna need to take into concideration besides...

i totally understand that it is not big enough but i only have enough for the engine so i was going to fit engine work out bugs and drive while i save the money to get the 727 and other parts to do so, so my question is
can the 5.7 hemi bolt straight to the 904,
and if it dies while saving for the other auto well so be it ,

the engine will bolt to the transmission - but requires a specific flexplate - this flexplate can be used for a 727 as well

may i ask what sort of specific flexplate ,
no one over here would know that (aus)
thank you so much fo ya help

The flexplate is also available from Mopar performance # p5153753, got mine yesterday. You also need to use a neutral balanced torque converter.
