[DeTomaso] Finally, the IR manifold is on the engine.

Jack,

There is a photo of his jig, near the photos of the manifold.   
Basically he used the principle of any line not cut perpendicular to a  
tube creates an oval, instead of a circle.  He sandwiches the throttle  
plate between two halves of a cylinder that has been cut at the  
desired angle.  Ingenious really, then just machine to the external  
surface of the cylinder.

You not only get the oval shape you need, but you get the proper angle  
on the edge to match the inner bore of the throttle body.
