The MAF sits correctly but I will check the voltage readings. Thanks for the help

 

Thanks to all for the help. I finally traced the problem to a broken ground wire in the MAF circuitry. Now repaired, it runs terrific.

 

Unreal! Good luck with it!

and Happy Thanksgiving!

 

Krewat: I appreciated your help. Although my vehicles aren't listed, I no longer drive an F-150, but use Ford injected V8s -with AOD in a 1930 Buick, 1948 KB-1 IHC and a 1984 volvo wagon. Main transport is an Avalon and a Miata. Have a great day

 

terry -- any pics of these - i am looking at putting a 5.4 in an 82 f350.

right now, i have a nice running truck that gets 5 mpg...,. i am afraid to have a truck that doesn't run when i'm done. any advice? what did you do?

 

If it doesn't run, it will be great on gas

Seriously, It's good to see more of these transplants. These are good engines (even though they are large and tight in many older engine compartments). I wonder how a Lightning 5.4L would run in my 77 F150??? It gets much better mileage than yours does right now 6MPG

 

you must have a 400 in that too......

I'm trying to figure out the sensors and computers i need. Are there diagrams for these things?

 

Actually, it's a 460 with a CompCams 268H cam, Headers, Flowmasters, Performer intake, 750 Edelbrock carb with a C6 and 3.50 gears.
