I am rebuilding a '69 351w engine and need some help. I want to make around 425 - 450 HP. What parts would you guys use? Should I do the roller cam conversion or stay with the mech flat tappet? I have power disc brakes and need to maintain a safe vacuum. A rough idle is okay as long as it is drivable. The car will be used on the street as weekend fun. Please include the specs of the cam so that I can do some research on which company to use. Your help is appreciated.
