Re: 302 z28 motor carb question?
With a slightly modded 302, 12.0 pistons -140 cam, and some port work on stock 186 heads and 4.88's back in the 70's I ran a 750 dbl pump and loved it for the street. I recently ran a 4777 650 dbl pump on a stock spec built 70 LT1 in my Z and loved it. Only problem you really need to worry about is the price of gasoline. In the 70's gas was cheap, today it's a lot more and you will use it up fast with dbl pumpers.
