318 MAX fuel economy builds?

nope, pen and paper. it only lasted until the high center rib wore down even with the rest of the tread. and with Wifey driving it it never repeated it either.
but it was 22 MPG both ways that trip thru 4 tanks of gas.

Well that gives me something to shoot for! Maybe your later OBD2 computer does a better job of controlling the fuel and timing than my 1994 OBD1 computer does. I know it controls the transmission between gears 1, 2, and 3 whereas mine is old school hydraulic control in the first 3 gears, but that won't have any impact on highway drives.

Just to be clear, I didn't build the car for fuel economy. It's just a game I like to sometimes play to see what I can squeeze out of the car since I'm already recording distance driven and fuel used. It has also been fun to see how my fuel economy has changed since I put in the EFI engine, made some modifications to it, then put in the OD transmission, got it dialed right in, etc.

Next mod is to swap out the 3.23 for something more aggressive. I think the shortest gear available for my 741 case is 3.73, so maybe that's the ticket. It should make a big difference on the fuel economy in the wrong direction.
