As for why I want the big first gear: With it I can nearly match the performance of my stock first gear with my stock 3:43 rear end.
With my planed 2:14 to 2:42 rear end it would be a stuck pig with anything less deep.
BUT with the 8L90's tall first 3 gears I can expect even slightly better take off than my stock gearing.
And with all 8 gears reach a much lower RPM range in over drive, around 1000 RPMs at around 80 MPH.
I can have my cake and eat it too, This engine and transmission looks to be even a hotter hot rod off the line and all the way to cruising speed that my old drive train, and be much more able to match RPMs to what ever speed or mountain I may encounter on the road.
So please look at this chart, note the power ranges and the cruising ranges...
And then looks at the chart for my stock setup:
