The best way to make horsepower in any engine is to make it breathe. Intake, heads and exhaust are where you need to concentrate. First you need to decide honestly where you want the horsepower to happen. Do you want good streetable horses or do you want a 8 thousand rpm screamer. Any intake manufacturer can supply you with a quality manifold. A four bbl carb in the 600-650 CFM range should be plenty for a street driven 351. Headers and a good exhaust in the 2.5" diameter range are a good place to start. As far as cams go, the sky is the limit but once you decide where you want the power the cam manufacturers can help you decide what you need. If money allows it go for some better flowing heads. There are several on the market in a wide array of prices. Get a good ignition also. MSD makes a good system that will add anywhere from 10 to 20 horses (they say). I can say from personal experience the MSD's make a big difference. As for torque convertors? Anywhere from 2000 to 2800 rpm is a good range for street driven cars. A good place to start is go to Summit's web page and order their catalog. They have a tech department that can help you with ANY questions you have about equipment and it's application. Not trying to advertise for them but they've been extremely helpful to me on the last two projects.
