Can I get a /6 in the 7's?

Some great responses! it's appreciated. My intention of building the /6 is just to try something different. I'm 56 and I've drag raced, owning a slew of dedicated race cars, from stock suspension, back halved and full tube cars. Still would like to bracket race some, and run around the street when I want to. I hate to remove a bunch from the car, like seats, etc. My plan was to use the stock crank, shot peen rods, forged pistons, mill and heavily port the head, Clifford intake and Holley carb. Cam will be aggressive. On top of this, I wanted to hit it with a 150 shot. Rear gear at least 4:11, with all Cal Trac gear. What can I realistically expect in the 1/8th with this combo?
