Based on Bill Harrelson's recommendation, I obtained and had installed 
an airbox from an RV4. I have downdraft carbeurator. I believe that the 
airbox with full oval filter, smoothed out the airflow. Sometime in the 
next month I will put out real numbers. Right now I know that the 1,2 & 
3 cylinders are all 70 deg. lean of peak while the number 4 is just 
reaching peak. I think that this is just fine for the carbed engine.

On the down side, the intake had to be extended down by about 2 extra 
inches.
