    Ok I am pretty sure I know the issue ... here's the rundown ... I got a new motor bput 450hp ...a fresh rear end... nv3500 5 speed and a 208c t case ... axle gears are 3.08s and running 33s ... the trans has lest then 5k on it also... what I want to know is y i get so much bucking? the only thing I having touch is the t case ... figuring that's seen better days ... I also got way to high a gears .. going 3.73s eventually ... it's just it'll buck in gear at lower revs ... thoughts?
