worst parts about 305s are the heads and exhaust..........ive seen a 305 make 30 more HP from just from full exhaust...

and my epa gas milage is like 18 city 25hwy

well the good thing about my motor is that the 83 Z28 305 HO motor came with bigger heads than the normal 305 and mine will have some long tube headers with some flowmaster super 40's i have laying around in the garage
