i was gonna say i think mine are 3.73's but i didnt want to provide misleading information & your rpm's at the given speeds sound familiar to me & my experiences.

id be lying if i said i hadn't (on more than one occasion) buried my 85mph speedo - but its not something i TRY to do....although the frequency of touching 80/85 seems to increase w/ time, experience and comfort.

at 1100 rpm my MBE4000 (aka DD13) is almost bogging (when in 11 or 12 gear). Im not sure that the move to a 3.50 would be worth it to me, especially since the interstates that i run on are all 70 if not 75 mph.....but the 3.00 would seem perfect (assuming i kept it at 70 all the time)....i wonder what it would be like w/ the 3.00 in backroading to/from highway.
