The stock gearing is 2.45/ 1.45/1.00 for the 727 and 904. I bought the low gear set for my 904, but haven't decided if I am going to use it just yet. I woukd like to get my converter issues fixed first. But I only have a stock stroke 360 magnum engine. Looks like a stroker wouldn't need the low gear set because of the extra torque produce by the stroker crank. But like most of this stuff is above my pay grade. Lol
