Once you start pushing the 300+ hp streetable? will become a issue for many. Esp. with a AT tranny as you no dout will end up needing more stall speed and Much better rear gears This to will hurt the daily driver As the motor will then be reving much higher. A example is when I was useing mine as a daily driver.The cam that was in it ran from 3800-7200 with a 4speed and stock 3:08 gears The cam wasn't to happy at 40mph in 4th had to down shift to 3rd to keep the cam happy and Not make the car Lope/Hop along with the cam. i may thought it was cool to Hear the tires Bark with each Lope of the cam But the Motor wasn't very happy.
So you may make a Street Car a Racer But you will not make a RACE car a streeter. So really think about what you want. You may have a Mild build of both. But you will never Really Get The best of Both worlds when it comes to the Maximum Power with a naturally aspirated motor. The cams Itself won't let you nore will compression running Race fuel.
