Re: What Heads, cam, intake etc for 351w
If it is for drag racing it is one thing, but if it is for driving on the street, that is very different. I don't think you're going to want to take an old engine up to 500hp with just top end bolt ons. Any serious build up requires the whole thing to be done, then a stroker kit can easily be part of the equation, giving you the cubes to make elevated power levels. You should get a real seat-of-the-pants boost in performance with good top end bolt ons, just don't be too concerned with hitting a HP number. Rear gears and a torque converter, if it is an auto, should probably also be considered part of the package.
