Ford's C6 hd pinion set

Has anyone here used the Ford HD 6-Pinion wide ratio gear set kit. Ford racing lists it and says
"This kit adapts gear train componennts from the new 4r100 trans to all c6 trans. The 6 pinion planet assemblies provide 2.72:1 low and 1.54:1 intermediate ratios as the discontinued m-7398-c gear set, while increasing torque capacity by 43%. Kit includes the hd #5, #7, #8, and #9 needle bearing components. Provides drag racers with more acceleration and tow vehicles or motor homes with more pulling power without changing axle ratios. Note: No machining is required on m-7398-f kits!"
What differences have you noticed if any one has used this. What are the stock ratios in my 79 c6?
79 f150 4x4
408,Crane 941
Scorpion roller rockers
Performer intake and carb.
hmm, 434 stroker?

I haven't used the kit. I have looked into it though. Stock C6 ratios are 2.46, 1.46, 1.00.
Thanks, SoCal.
