1981 Ford LTD - This is the way I'd have liked to run the throttle body. Didn't work out that way. Too close to the distributor and not enough hood clearan… 1981 Ford LTD - Would have looked nicer like this but it fits best facing the passenger side. Oh well. 1981 Ford LTD - One block of 1" x 6" 6061 aluminum. Raw material. There's an adapter in there somewhere. 1981 Ford LTD - There's a lot of layout work getting to this point but it all comes down to this. Lines on aluminum. This is the throttle body elbow side.… 1981 Ford LTD - Laying out the intake flange side of things. This is an idealized version of the ports. The intake will need minor work to match. I'm keepi… 1981 Ford LTD - Starting to cut out the ports. Cut out a pair of circles with a hole saw to get a bunch of material out at once.

They are blind tapped so there's no chance o… 1981 Ford LTD - A little work with sanding rolls really cleaned up the ports. Not too shabby. I also ran the router down the center divider to clean and st… 1981 Ford LTD - Studs installed. The upper plenum fits it perfectly. I need to cut a gasket for it because Ford used an o-ring and I changed the port just… 1981 Ford LTD - Plenum bolted to adapter. Just a little step here and there. Won't hurt anything. 1981 Ford LTD - The way it'll look on the car. Not too shabby for a guy in a garage with a drill press and die grinder.
