After all the considerations I have decided to stay with the Mopar dual plane. I went ahead and bought a new one. My eight year old mopar seen some months of overheating and the carb. mounting surface is now not flat and filing and stoneing did not help a whole lot. I just can't trust the old one anymore so new one on it's way thanks to Summit. Order before 9:00 pm and ships on the same day and in the same state of Ohio I get to pay state taxes! Thanks for the help guy's. Dave.
