I'm planning on totally rebuilding the cobra. vortech s-trim charger, new paint job, suspension will be revamped, and i'm going to add t56 6speed manuel trans. But my question is this, the car has 82,000 miles on it and i'm thinking of taken the car to have the engine rebuilt to handle 500=rwhp without a problem. Does anybody here feel that this is necessary or a waste of money, I'm looking at spending 7,000 alone on the engine if I decide to go through with it. Includes pulling the block apart. the heads will be ported stage 1 just to clean out debri from fluids and build up, p & p intake and a new cam profile to go with it as well as having the compression changed to handle the charger better down the line. The work is garuanteed for 2 years. I'm told the car will still smog legal with this setup, and can still be a daily driver though it really will be my weekend car. And similar set ups have seen up to 600rwhp and mid 11's with good amount of practice. Any response will be most helpful. This is looking to be a 1 year project for me.
