Re: [AMC-list] Need flexplate application help

[Todd Tomason <jayscore@xxxxxxxxxxxxx>]

In general, the 360 and 401 used the 727, the 304 used the 998, and the 258 
used the 904.  The flexplate is balanced to the engine.  When my son broke a 
piston in the 360 in his 78 Matador, we swapped in a 304 out of a 73 
Javelin.  We had no problem mating the 304 up to the 727.  The 304 flexplate 
already had holes drilled for both the 998 and the 727.  My guess is that 
the unbalanced flexplates were the same for all the engines, and therefore 
had the holes for both transmission sizes.  The appropriate weights were 
then welded on to balance it for each engine size.  AFAIK, the torque 
converter is specific to each transmission.
