my car is a chick magnet/ lug bolt questions

[rattlesnake]

i love my 84 380 SE. it is a simply gorgeous car and the ladies like it a whole lot too. i have fixed my problems with my smog pump thanks to the help of you guys(and ladies) on this forum. i have another question though is there any way to stretch more performance out of the car?? like i have heard the 380 is a really nice engine and i love it some have even said it is better than the 500 is that the case?? but i really love to modify little things here and there to make my car as beautiful as possible. also i have a set of rims that were discontinued and the lug bolts were also discontinued and i can no longer get them is there anywhere that i can possibly get them right now i am using the short ones they work but they just do not look as good as the long ones that you can see.. thanks, george
