Well Motive advertises 3:90's in their ads and MM&FF did a write up on them awhile back
I run 3:73 and went a best of 11.80 @ 115mph, should go 117mph+ this year and hope for 11.40's or quicker when the rear goes in. I trap 5200rpms on 26" x 11.5" ET STREETS and launch at 5800-6000rpm. Plans to go either 4:30's and 4:56's and turn around 6400 through the trap, which will match my cam. That is something no one has brought up, it really depends on your combo as far as how much gear to run but you will be fine with either the 3:73's, 3:90's or 4:10's NA.
Jeff how is this season going? Will you be up at Maple Grove?
