I had many single purpose race cars for many years and watched the grass grow up around them. Never again will I have a dedicated race car. My car is a 77 Road Runner , full interior , heater , radio , wipers and even a functional clock on the dash. It runs 10.80s all day with full exhaust and et streets on the back. 422 inch 318 pump gas with a small roller cam Eddie heads 950 Hp Carb 727 trans and 4.30 gears. It will run in traffic all day and gets pretty good mileage. I don't drive it as much a I used to but it will still go to the grocery store every once in a while. " Beer Run "
