Default dimensions for the cut
David, et al,

Anyone with the Edelbrock Air-Gap...would you measure the depth of the cut in the plenum...? looks like 3/4" or so...may as well try to duplicate the Edelbrock.

Have masked off the manifold .passages and will be using a large bur and 3/8th's drill to grind the aluminum...I am sure the aluminum is harder than I think.

Seem to have misplaced my Bridgeport Mill...

Pete
