how much HP do these usually add?
i was just wondering if you could tell me how much HP gain i can expect from these add ons?
Demon 650 carb
Hooker comp headers with 1 5/8 and 3" collector
MSD ignition dist( i know not much but is there any increase)
true dual flowmaster exhaust

Do you already have headers? if not that will make a big difference but just changing to different headers isn't going to make huge gains.
The Demon carb may be a bit more responsive but I can't see a big power gain over the Edlebrock.
You might look at a little bigger carb like a 750,looks like you have enough motor to handle it and then you'll see some gains if it's set up right.
You have an MSD dizzy listed in your specs already so what is the change there?
Whatever it is I don't see any gain unless you are replacing a stock unit and then only modest gains mostly attained through higher rpms available and a little better advance curve.

are there any bolt on's that could give me the 30-50hp gain?

Well that depends on what kind of car you want it to be,as in how streetable VS mostly a hotrod.
I wouldn't say that but as I said above it depends.
You might need to go with a more aggressive racing cam and a different intake and bigger carb or more than one carb but you start pushing boundries if you want it to be a daily driver rather than a hot rod toy.
Look at Camaro69's car with the dual carb tunnelram set up,something like that with the right cam can probably get you there or close but it's not going to be a good daily driver and it'll eat a lot of gas.
All the power will be top end high rpm making street driveability a problem at least in the context of a good daily driver.
Why are you looking for that much power would be my question?
450hp in a street driven car is quite a bit,if you haven't driven a car with that much power before you might want to just give it a whirl lol.
Looking for really big hp in a reliable street friendly package is expensive,you're looking at turbo or supercharging or a big monster big block.
One other option for a quick burst of extra power is a NOS kit,that will be your best bang for the buck getting the numbers you are seeking IMHO and when not in use your car would still be streetable.

yeah i was thinking about getting a supercharger but there like 3000 for a 100-150hp gain..so i was also thinking about NOS..like a 100-125 shot..what would i have to do besides getting a different intake manifold so i dont blow my engine?
