you sound alot like me. changing your mind about what you want ( combination wise)
first off it sounds like you want a somewhat street car but dont really need it for daily purposes so you can go a little bit crazy. Do you want boost, all motor, or both me and bugmans favorite all motor with a "little" bit of spray. Nitrous is very safe if done right but alot of people dont know what the **** they are doing so they do all sorts of weird **** with timing and fuel. this might help you out for as having a fun street car then turn the bottles on to blow down the drag strip or what ever pulls up at a stop light. If you do nitrous get the Digital 6 box from MSD it retards the timing when the nitrous setup is on automatically so you dont have to fiddle with the timing when the bottle is off or on.
if you want inches like most guys do.. just do a cleaned up 351. a .030 351 with a better bottom end wont cost you an arm and a leg but will be damn stout and can get a little more torque. in all honesty theres some bad ass little 306's rollin around so its not always about how many inches.its about the combination! i cant stress that enough.
the biggest thing is.. do you REALLYY have 10-20k to spend? because it wont get you any brownie points with us throwing dollar signs around. trust me some of us can throw more money at our cars than we know what to do with. but that doesnt mean anything. also, this comes from my road racing background. Id recommend you building a car that you can build off of later to go faster. get a good foundation with a cage and suspension, brakes, etc. so that as you personally get faster so can your car.
sorry its soo damn long.
