When you go to a blown setup, you won't need the Nitro. I have a very VERY mild blown deal, only 370" @ 10-1 compression and with -10% underdrive went 4.89 the first time I stepped on it. That was shifting at only 6,200 and lifting well before the stripe. I'm only telling you this, hoping to encourage you to spend your money on a supercharger instead of fuel. With a little overdrive and on a better track I think I should see some 4.40's or better. SOoooo, start looking for a decent 6-71 and you'll really get a kick out of it. Have fun, be safe.
