Small block combo suggestions

BTW, you mention six pack. Are all the carbs the right ones in the right positions?
Sir I've had them for about 20 yrs and have been fanatical about keeping them in position. Especially when setting mixture on rear carb. What a pain. Thinking of changing base plate in rear to one of the proform wt angled mix screws. Also may swap jet plate.
They are correct for small block app. Will tell you they are sensitive to the weather. With the cold starting down here they will be a touch lean but because it's seldom cool for long I have learned to just leave them alone.
On my prior combo which was just a 360 truck motor wt the six pack heads,exhaust and intake it would run 14.00 at a 102 mph. In the quarter I know it's not quick but it was built as a cruiser. Also it returned 18 mpg This new combo has some potential I feel but have to put in the time to tune. That's why I appreciate all of your help. Thanks
