The big inch engines don't require a lot for street use, a good valve job, pistons to get the compression to a decent level, hei ignition, cam, intake, and headers is about all it takes. Build the engine and pick the components, especially the cam, to make low rpm torque and it will be a pounder!!!

Still the best way to make more power is to make the car lighter. A good guide for weight reduction, every 100 pounds you take off will speed the car up by about .1 second....Takes a lot of $$$$ to buy enough horsepressure to take a few tenths off your et!!!!
