...Thats a very loaded question!You need to be very specific about what you want or need the car to do.Is it a "race" car or just your everyday street car?How streetable does it need to be?How reliable?Are you going for the huge blower through the hood look or are you going to keep it under the hood?How much boost?What engine?(I assume it is a 350)Is the engine fresh?Whats the compresion?Pistons?Cam?Are you going to run on pump gas race gas or a mix of both?Do you want 400HP or 900HP?You need to decide what you want the car to do and how you want it to work.

Im guessing you are very new at this. A lot goes along with putting a blower on your car. You need to know all the specs on your engine and you also need to have a good suspension so the horsepower doesnt rip apart your rearend. You definately need to answer blown 70s questions so we can help you out. But for a 350 I think a 5-71 Weind blower would do but they also have smaller ones. You should just check out their website.

Before you answer blown 70s questions you need to know what your budget is.

That is true...Budget is the MOST important thing!

The first thing you need to know is the compression ratio of your current engine. When you add a blower you are basically raising the compression of the engine. If you currently run on 87 octane you can add a few pounds of boost and go to 91 octane. If you currently need 91 octane you will need to mix race gas with the pump gas to take advantage of the blower.

This is the basic of basics in regard to this as there are other factors such as intercooling, changing the cam, adding alcohol injection and pulling out timing that can allow for more pounds of pressure. However the compression is the real starting point and from there you need to address things such as type of piston, fuel delivery, type of blower, and cam.
