What size shot are you running on your stock bottom end?
13k miles fresh rebuilt longblock
10k miles rebuilt tranny
75 wet shot ZEX system got about 13 bottles through it so far and ran a best time of 13.1@108mph on street tires.
You will need another fuel pump or switch your out to a 255, and you might need bigger injectors. Not positive on the injectors but it probabley wouldnt be a bad idea at that point.
