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?
