.......... And there was one poster there that said he did not like the spread of the A833OD. Jamies Hemi OD offering is way better than the stocker OD. I have one installed behind my 451 and before the Dana 3.73. Pulls 7000/55MPH in 1st about 3 seconds from takeoff. You don't even feel the drop to 2nd as I am still above the cam lower limit. With the big motor you don't feel it.
