1994 F-150 4.9 E40D SD to MAF
First let me introduce myself. I live in Fort Worth Texas and bought my truck used in 1995. About 3-4 years after I bought my truck I started having all the tranny problems and being young I just flushed the fluid regularly to prolong the inevitable rebuild. So now fast forward after years of torgue converter shudder I decided last year with my son starting college I would fix up the old Ford. I rebuilt the Tranny with all the upgrades and WOW what a difference. I have started doing the body work getting her ready for a fresh skin and now am working my way into the motor.
OK so I have ben doing a ton of reading to the point my eyes are hurting from looking at computer screens. I would preferr a conversion kit to convert from Speed Density to Mass Air Flow. I have seen kits for 302, 351, and 460's but no kits for the 4.9. If a kit is non existent is there a detailed write up that any of you know of for this conversion?
My reasons for swapping and correct me if I am wrong are slight improvements in fuel economy and I am also looking at a cold air intake with Cat back performance exhaust. I just bought a 24' fifth wheel trailer and want the best I can get from my big six.

The only MAF 4.9s are the 96 and 97 trucks. They are also OBD-II which would require a pretty extensive rework to implement on your 94. On an engine with no internal modifications there is virtually nothing to be gained by switching to MAF. Don't count on much besides increased noise from the CAI. Limit the exhaust upgrade to 2-1/2" if you are looking for a tow pig.

Now back on topic to Ranger, Ive been reading you can get 1-4 more mpg, better throttle response throuhout, and more low end torque by making the change. I wish there was more reliable information out there. I knew the 96s had OBDII and was wanting to stay away from that mess. Anyways any advice other than buying a new truck is welcomed. I can do alot to this old truck for what I am saving.

All that MAF gives you is more flexibility for internal engine mods which you are not contemplating and a somewhat cleaner exhaust.
What rear axle ratio do you have? At 4200 lbs you could be pushing or exceeding the limit
