How much slower is a AOD than a T-5

[Mr 5 0]

Mach I:

The converter is the major source of power loss in the stock AOD and a 2800 RPM stall converter makes up for that (stock stall is 1600 RPM). The shift kit compensates for the AOD's lazy shifting and the 4.10's compensate for the AOD's poor gearing.

I don't know about 'pulling hard' on a 3.73-geared T-5 Mustang (with equal engine power of course) but as a T-5 driver, I would be worried if I were racing an AOD equipped Mustang V-8 with the above aftermarket parts.

That said; every Mustang and every driver is different. This is just an opinion on my part, based on observations over time.
I still think it's easier to just buy or convert to the T-5 and be done with it.
