904 to 727 upgrade.
Agreed but it's just that most of us have been down the 727 road
and do not view going to a 727 from a 904 as an upgrade. It is the other way. Is the 727 stronger, yes, does it have more clutch surface, yes, but it is also heavier and does not come with a 2.74 low gear which really improves low end torque on the street and strip. This gear set can be found relatively cheap. Not so with the 727. The right version of the 904(999) is plenty strong enough for most small blocks. The low gear will allow a lower numerically rear gear ratio for better mileage while still having great acceleration from the stop light.
