I agree with 340mopar, 1969340dart, and 66dartman. It's not worth it!!!
When I was in high school I ran a 73 camaro with a 66 327 that was balls out with a M21 4 speed. Lotsa street races, lotsa tickets, and one smashed front clip cause some idiot crossed the line in his import. Im 28 now and I get "challenged" at stoplights by guys that think the same thing... "It can be safe it's the idiots that make us look bad"... There is a reason they have sighns posted about street racing all over Seattle/Tukwilla/Kent area. Don't give the cops a reason to follow you or pull you over just because your in a old muscle car, Its bad enough already.
Take it to the track and just laugh at the losers in there fart canned hondas at the stop light when they over rev the motor in the car that mommy and daddy bought them and have the cops follow them instead of you.
