Mileage question

Probably a stupid question, but, I have a 1978 K10 with a 1992 350cid, 700r4 trans, np241c, Rochester 4bbl (just rebuilt) just tuned up and oil change. I'm running 33's but not sure of the gearing. my question is, I'm getting about 3-5 mpg city! is this normal??? (it may also have a mild cam)
