Matt, You are right. You need to convince your dad to get the right cam.The blower cam is a must.The Weiand 144s work very well on the street.You will also need to use a carb that is blower frendly. the boost signal in the blower carb is much differant than a regular carb.
We have sold several of the Weiand 144s in the past and know the pit falls that come with them. Your on the right track if you can convince him. If you need help please feel free to get ahold of us.
We can save you alot of headache and some cash to boot.
