    N2o,is the cheapest way to add power.With a 400 block they are very prone to blown head gaskets,cracks,running hot etc.Put a 150 shot of n2o on it and call it good.

    Invest in a set of aluminum heads like the Brodix Race rite 180's or Dart 180 cc heads I would not go any larger and add a hyd. roller cam and lifters.

    What 2.02's or 2.05's?This refers to the valve size and not the port size.I would not bother with a single carb blower because you will have to spin so fast to get any boost out of it if you are refering to a ( roots style blower).

    While valve size is important the port size will have more of an effect on the engine.

    The LT1 heads have a port volume of 170 cc on the intake side and 62 cc on the exhaust side.

    i'm wondering..what would be the pro's and cons of a centrigual blower through a carb with his set up? yeah.. a set of brodix heads would be a big improvement . but how would the super charger perform?that would definitly put more strain on your budget. also you have to have compression low enough to be able to run pump gas and still build boost?

    With a good intake,carb,heads hyd. roller cam,and enough comp. ratio you should be able to do 500 to 525 h.p.One area we did not talk about was flow numbers.The general idea is to have good flow numbers with a small port volume.
