How fast can I go with built shortblock and some Nitrous. Im kind of in a budget due to a new house purchase. Im thinking of buying a built shortblock, bumping the KB to 18-20#s and maybe run a shot of juice 100-150, plus everything else on my sig. I race on an 1/8th track across the border and my competion is mustangs. Im searching for low low 7s. Is it possible with this set up? Ive ran a 7.67 so far with my current set up.
