I will be building a 350 chevy small block, it will probobly be a shortblock from napa or pepboys. I was wondering what will I have to put in this to have it crank 320- 350 horsepower at the flywheel ? I was thinking about edlebrock preformer package ( heads,cam,intake and carb ). I know that i want about a 9:1 compression ratio. Is this a good idea or a lost cause. what about preformer rpm package.
