Hi, my name is Steve. I bought a nice 1968 Chevy Nova last summer, with a stock 250ci engine hooked to a powerglide. I love the car, but would like to have some more fun with it.
I don't want to get into a cam change or a complete engine rebuild, but I would like to get some more power out of the old 250 6.
I turned the top of the air filter upside down, to get some more air flowing, and was I was impressed with the extra horsepower I felt.
I was thinking of adding a bigger carb, and maybe a different muffler, to get some more punch out of the 250.
What would be a good carb to run on the stock intake, maybe a 500cfm 4 barrel? Also what would be a good muffler, to add some sound and power, but still remain quiet at low rpm?
Also would changing gear ratios to say a 4.11 with 32 inch tires give me some more acceleration?
Please give me some advice on hopping up the 6 so I can give a hard time to the stangs in my town....cheers Steve
