The tunnel ram intakes are not hard to tune carbs on
Buy the other carb like you have and the linkage needed to run them one to one and set the idle mixture and idle speed with the motor warm up and go drive it You'll love it once you drive it, there is no magic to tuning carbs, one, two or three
Actually the tunnel ram carbs mounted in line are way easier to tune than with them mounted sideways like most Holley D.P carbs have to be mounted on the tunnel ram intakes
As far as all those advocating small carbs on a tunnel ram intake are not some one who has taken the time to tune the bigger carbs for a tunnel ram, if you want tire smoking power put the bigger ones on now
Having two carbs let the motor breath easier and makes the fuel distribution better, especially at WOT
