Army of Six
Well-known member
So i bought an old 67 Econoline so me and my family (6 of us total) can all pile in and head to the beach whenever we want. It had a bone stock 240 cu 1bbl with a manual choke and a C4 automatic. I got so tired of trying to start that 240 on a cold (by southern California standards ) with the manual choke. I rebuilt the carb but could never quite get it dialed in. on top of that it was a bitch for my girlfriend to start (hot or cold)
anyways, i have messed with fuel injection with my old GTO so i knew what i was getting into.
this post is just how i went about it, maybe it will help someone down the road.
Here is what i started with...
and here is what i ended up with....
basically with the help from you guys here on this forum i found out that the 1987 fuel injected manifold will fit the 67 240. that seemed like the easiest way/cheapest way of doing it as opposed to getting a single plane aluminum 4 bbl intake and having bungs drilled and welded in and having a custom fuel rail fabbed up. i scored this 87 4.9L lower intake on ebay for under 20 bucks shipped!
because of the small engine compartment in my 67 econoline i had to shorten the intake runners. the masking tape you see is what i had to take out to make it fit. all the runners lined up pretty good. just minimal porting with a dremel tool to clean them up..but the funky dog leg in the number 1 runner needed alot more time with the dremel to get it right.
here is a pick of the newly cut and welded up 10 dollar e bay manifold during mock up...
i didnt think that i could get the matching upper intake to fit under my little engine compartment hood so my plan was to fab up my own upper intake plenum out of mild steel. i bought a 3/8th inch think cold rolled steel and had my friend bore out the 6 intake runner holes. i then cut up some mandrel bends to form the top and sides and then welded in the sides with 16 ga sheet metal. then i fabbed up and welded the throttle body base and neck to the upper plenum. i took my time welding but it still warped the flange so i had to have it milled to flatten it out.
here is a pic during fabrication...
here is another pic from the back side....
as for the throttle body i bought on for a 3.9L dodge or something. i wanted to make a nice cold air intake so cut up some 3.5 inch and 3 inch mandrels. the air cleaner sits pretty much behind my drivers side front tire. ( i still have to make a shield to protect it from water/debris) here is a pic of that (the electric fan is for my oil cooler)
i will post more (with pics) of the fuel system, ECU and wiring tomorrow.
