I have a 72 2wd blazer with a stock rebuilt 402 that I am wanting to get a little more powere out of. Here is what I am thinking. I bought a edelbrock pro flo, looking to buy a set of 98cc closed chamber heads, going to get a cam, bought a set of headders and 2.5' stainless dual exhaust. I going to get a 2500 stall and I bought a set of 3:73's and locker. How do you think this combo will perform? What kind of horsepower do you think I will achieve?
Thanks
