360 build need info on parts

wow lots of great info, my goal is a powerful street, weekend driver but not so much power i start breaking stuff. 280 to 300 horse @ flywheel i reckon. but doing it on a budget of about 1000 bucks or less. i dont think its to unreasonable to ask that from the 360 considering the 273 thats in the car now was dynoed @ 270 when the previous owner built it using used parts and swap meet stuff. luckily i should be able to carry over the 273 holley strip dominator intake and the 750 vac. holley carb, along with the headers and electronic ignition. this is my first mopar build and really excited to do it. thanks guys
