what to know what effects will a little bigger comp cam kit (computer friendly) vortech iron heads with matched intake manifold from sdpc. Hooker headers with y pipe , afpr, with ported plenum and bigger runners. what effect will these have on my stock 305 block motor tpi i dont want to upsize at the moment

 

It costs you $350 for the custom ERPOM. You are spending all that money and trying to make it work with the stock chip. Even if it does work, it won't be maximized for that application. With all that and you still want to limit your choices by going computer friendly?

 

so then if i add this chip it works fine your saying. im asking if it will work and on a 305 block. if you throw heads on a car youll get a difference

 

It should give some good increases provided the cam is matched to the rest of the system. 1.6 ratio RR wouldn't hurt either.
