roo is on a distinguished road

Express; 3.55 rear x 1.50 3rd gear ratio = 5.35. At 5800rpm 107mph with 33" tall tires not accounting for converter slip.
R/T; 4.10 rear x 1.50 3rd gear = 6.15. 5800rpm would give you 90mph with 32" tal tires again not allowing for converter slip.
You'd have to rev to 6800 to reach 106mph with the 4.10's in 3rd gear.
