Do you have a dyno sheet? You will want to shift a few hundred RPM past where it makes peak HP. It's a balance of keeping it at the highest average HP. Ideally you wouldn't want to shift until power has fallen off to a lower point than where it will end up in the power band once the shift occurs.
Mine peaks at ~6300rpm but likes to be shifted around 6700rpm...might like more but that's as high as I want to spin it.

I figured with that short of a tire on the back and my 3.73 gear it will be like having a 4.10 gear and probably will go through the lights around 6400?

best run I got last night was a 8.06 (1/8 mile track). converting it to 1/4 mile time its a 12.65. truck was really rich all night. it needs a smaller carb and a 4.10 gear. i went through the lights last night in 2nd gear and only at about 6500 rpm lol.
