Just FYI.. Kind of posting this so I can access it later.. and to build on it.. Next I'll add the rear end ratios.. and tire sizes.. (someday.) If I've messed up some the calculations.. someone let me know..

NV4500---241 (2.72)--- 205 (1.96)

• 1st --- 5.61 --- 15.25 --- 10.99
• 2nd --- 3.04 --- 8.26 --- 5.958

Lots of gears close together on the 205 case.. nice split on the 241 case between gears..

 

Heres what I have with r&p ratios...

Does advanced adapters make a kit to put cast-iron death 205 behind our NV4500's if they do I have a spare 205 laying in the garage !!!!
