Making up material list and need to get the engine bed mount located to the firewall first. Using "Corvair Flight Engines, and Corvair/601 Engine Installation Manual" to obtain the correct dimensions. Talked to William Wynne today and confirmed the dimensions before moving the bed to that location in the ViaCad model.
Now that is done just make some quick tube connections and measure the line length. Add 4" to length for comfort and carving. Better to have to much than not enough.

Talked to Roy Szarafinski today also and we both agreed, make the long ones first. He has my engine block and will get me the missing dimension to the prop so I can rotate about it's axis for the final location of this design.
