I am planning on putting a remanufactured 351 in my 1995 f-150. It will be a 94097 351w longblock. Its gonna have MAF but i am gonna try and use my old fuel injectors from my 302 and other fuel system parts. If I buy the Ford racing MAF conversion, will it work just the same as it is suppose to?? Im not to sure how this conversion hooks up to the exsisting harness? I heard the engine wireing harness in my truck now will also work with the 351w. I would think there should not be a problem with hooking this conversion kit and having MAF. I know of alot comapies that make new wire harness's like fordfuelinjection. But then i would have to buy that along with new computer and MAF sensor and air filter tubes. I think the ford MAF is easier. Well any ideas??
I have orange top injectors now wich are 19lb. I posted before woindering what the stock injector size for 351w was and i got back that they use 19lb also same as 302.
302 & 351w use 19's for sure. the question is why are you going to mass air to begin with. its only necessary if you plan on modding the motor to a point that the stock speed density wont like. but installing a reman 5.8 wont need maf for sure. i say stick with the efi setup you have for now and mod if need be until the system wont run well then swap. personally you can build yourself a mass air harness cheaper with the info from fordfuelinjection.com. even the ford kit requires a computer change just like the FFinjection site does.
i thought that also, but i know SD doesnt take changine engine parts out that great. I am goin to be putting on a new set of Heads from edelbrock and a new upper and lower intake also from edelbrock. I wasnt sure if the SD would take well to those changes. And the Ford racing kit does come with a new computer i belive, at least it shows one in the picture. Also the engine will have roller cam, i guess as you just told me though my 302 now has roller cam also. I have heard alot of good things by switching to MAF even on engines that arent heavily modified.

Reason: Engine is roller cam
are you running a 5 speed manual tranny or auto? if its an auto the mass air swap is more spendy because the tranny must have a stand alone ecu. if its a 5speed manual then the ford kit will work just fine.
the gains are a slight increase in mpg and the ability to use a wider range of cams

It's ok if it's a non-EOD. The C6 is an automatic but is not shifted electronically by the ECU like an E4OD.
They do say the throttle response is better with the MAF. And they say it can get like 2mpg better, about 15%. At these gas prices, that alone could pay off the mod in like 10k-20k miles if you don't get ripped off in your conversion parts.
no need to worry, I got a 5 speed manual in it. I want the MAF just cause once im out of the Army I want to make that truck into a pulling truck. I want to put a better cam and a supercharger. I figure knock out the MAF conversion while im droppin the new engine in. Well as always i get great info from yall thanks alot
I did the FMS mass air conversion and its simple...you just plug in an adapter in-between your computer and engine harness, and the adapter has your new injector wires (numbered) and your mass air wires. i did notice better throttle response...and maybe a few horses
Just some thoughts for all of you out there playing with the SD to MAF swap. I did that on a 90 Ford F-150 (SD to MAF I mean)....Used the Ford kit. Then started modding...huge injectors, heads, Vortech, you name it....wasn't happy with the performance or the driveability...SO! I tried the TwEECer..of course all the while ordering MAFs matched to injectors, etc....did it all right...still hated the driveability....not reliable tunes, wasted dyno runs on and on! Finally found the CHEAPER solution that is VERY nice and easy. I went back to SD but I went a stand alone that PLUGS RIGHT IN....sold the MAF parts to pay for it completely!!! I bought SDSEFI...don't need a laptop (built in programmer). It is VERY simply and RELIABLE!!! Doesn't have the power of, say Accel DFI but wow it is a simple, easy to learn, powerful FULL Programmable system. I bought a straight plug in from wmsracing.com but I am sure there are other sources.
Having owned SDSEFI now for a year, it is a million times less cumbersome than a laptop computer in a two seat pickup truck! The system has shortcut buttons built into it and comes with a base map tailored (down to the cam) to your motor. The company that designs the EEC-IV kit (wms) is AWESOME to deal with...great guys and very knowledgeable. I am not going to lie and tell you that you don't have to be intelligent and understand fuel injection to tune it but having personal experience with Accel DFI, Holley Commander, and TwEECer...this is the way to go for a reliable, SIMPLE system that is truly programmable. The others are more powerful but have negatives too. It all depends on what you are looking for. As for price, buy one good MAF (Pro-M), TwEECer, a laptop, boost retard controls and you just spent more. I am running boost so I made out great.
