I would blow it first, then you can always stroke it later
Doing a stroker kit obviously involves a total rebuild of the motor, since its apart, gotta do this..Etc.. If the motor is tired, this is pretty good way to go, your car does not sound too tired though.
If your motor is real tight, stick to a blower, or NOS if you are mostly into better 1/4 times. I would prefer power avail all the time, the bottle does not last very long.
