Ok this is what I have : 4 bolt block, camel hump heads,870 street avenger carb, 142 weiand blower and everything I need to have it put on.

Now I was wondering what kind of pistons, rods, crank, cam, ect I should run in it. I want to spray 100 shot of nitrous (nx kit). Where do i start? This will be droped in a 77 camaro with a turbo 400 tranny with manual valve body, 3500 stall, and a 10 bolt 8.5 rearend what gears should i run on the rearend?. This car will be driven in town fri and sat nights only and will be taken to the track every now and then. No highway driving or daily driven.
