My fear is 10 mpg. I have 3.42 gears and a 5 spd.
I am trading one of the 600 600s for a good 500. So I can play. My research reading indicates the 500 would have more velocity. Velocity = throttle response. Edelbrock says tuning down a larger carb does not make a smaller carb.
With one remaining 600 cfm (unsure if friend wants 1405 or 1406) and a 500 cfm. I would have the option of trying the 2bbl. The 500 and one of the 600.
I I am furloughed next week. I have never swapped intakes yet... wish me luck.
