Ok, where do we start? My first question is you planning to drive this on the road? If so, the answers will be more difficult as you will never get a smooth or comfortable ride. However, several problems can be solved on the front suspension with some slight modifications. First go and get a stiffer and larger spring from a full-size Chevy truck. Most likely you will have to get shocks that are longer and that is easy enough once you find the full travel of the shock needed.
Actually with the newfound horsepower, you will need to find a latter bar set up so that the body will bite to the rear axle and the tires will hook up. Another not so easy solution will be to put wider and taller tires on the front and rear. I would put at least 15-inch wheels and tires. Also, anything you can do the put more weight in the back to balance the weight load.
If you are racing on the strip then, that will bring a whole bunch of question to the table.
