how would you guys built it?

very true caferacerx, i know that my dad's 69' charger falls into that second category. It's a very aggressive 440 overbored atleast 30 (maybe more i can't remember right now) with a very rough idle. It scares me, dad steps on it and it pulls very hard all the way to 6 grand. It's a pretty good car on the track considering that all the chassis parts are pretty near stock. but it sits more then it drives just because it's not that driveable. it's got 4:10 gears and revs at 3700 going down the highway at 50 mph. We have to roll it out of the garage and to the end of the driveway because mom gets mad when we start it to close to the house, lets just say it runs a little rich and has 3 inches of loud flowmaster exhaust all the way to the back. I know what you guys mean about drivability so that's why i'm trying to find a happy medium of drivability and haulin' on the track. Thanks for the tips guys!!
