340 engine ?

240 km Well I hope you are upgrading your brakes, theres all type of nice kits to pick from. You got $1300 for a set of heads, you should have another $800 for better brakes. Buy the best tires you can get too. Might want to get a spoiler in back and I would throw 100 lbs of weight in the trunk. Do what I did--subwoofers and amps--I can hear my stereo just fine at high speeds, well not at 240km but I think I would still hear it at that speed. Its great, I hear nothing but music if its loud enough and the car shakes at the stop lights :glasses7:
