1978 Chevrolet Nova Hatchback

I purchased this '78 Nova a couple years ago from a friend for $800. When I got the car it was completely stock from the wheels to the engine. The wheels which I now have on my Nova are a set of 15" American Racing AR-23's...although I'm not entirely sure what they're wrapped in. The trans is the stock TH-350. The engine when I got the car was the original integral head 250cid inline-6, but that worn out engine had to go. I purchased a remanufactured 250cid of an earlier year from Jasper Engines. To this NON-integral head engine I've so far added an Offenhauser 4bbl intake and a Holley 500cfm 2bbl. Although I'm only getting 6mpg at the moment because of the carb, the car is my daily driver with less than 90k original miles.
