11 second smallblock...how would you build it?

hey guys, all good suggestions and feedback here! this is what i was after, everyone's opinion on how to do it...as far as my car goes, i wasnt so clear about it since i was just looking for general, but since this has become more specific:

71 Scamp with a 340 currently...weight is probably about factory, no real lightening has been done other than no a/c, no power brakes, no power steering. I realize that chassis is just as if not more important than horsepower since all the power in the world means nothing if it cant get to the ground. Right now ive got /6 leaf springs with a leaf added 4 clamps in front, 1 rear, adjustable snubber, comp 3 ways in the rear, front end all worn out stock /6 t-bars and shocks...was thinking of later this summer changing to the calvert 90/10's depending on cash to see if they will make a difference...This future combo im planning will be going behind an 833 with a v-gate and slickshift synchros

regarding the nitrous, its something id like to do in the future, and id like to limit myself to low 11's just because i know anything faster will be a ticking time bomb for a 23 spline 833 (and no, im not switching to an auto)...in reality, if i can actually get the car to run consistent high 11's on the motor, ill probably be a happy enough guy to not even need the gas anymore. However, id like to build with it in mind for the future, so its a consideration during the buildup

in regards to heads, im so very tempted to pick up a set of Brians RHS heads, but because money is tight, i have to figure out first how much doing the stock heads will be...if its close to the price of the new ones, id definatly spring for those

anyways, please keep all the opinions coming! all the suggestions are eye opening and help out alot!
