As quick as they can be, most of the muscle cars I've run into are pretty mismatched. I still haven't lost to one.
1970 Boss 302 (wasn't even competition, he was running like crap)
1969 Coronet 383, tons under the hood, had him hard until it got moving, then I barely had him.
1972 Barracuda 340, heads, cam, intake, headers, gears, drag radials, HD 4spd, everything and the kitchen sink. He pulled me out of the hole, but I took him by 80mph.
1968 Grand Prix (something like that) built, fresh 428. Had him by a few cars, wherever he wanted to run.
Probably some others, but those are just a few.
