MAF Kit
Has anyone bought the Ford motor sport conversion kit? I was reading In PAW cataloge about it and the description says it works for 302 and 351w engines its like 600 dollars and comes with everything. Is this the kit everyone is talking about? Does anyone have a PN# that is the correct one for a 351w so i can crossreferance maybe?

the kits are the same for both motors. go threw summitracing. or u can get on ebay and buy a nice maf meter and a9p computer 87-93 for the year. make sure the meter is calibrated for your injectors unless u plan on upgrading them to. and then buy the maf harness either off ebay if u can find 1 in decent shape, out of a junkyard or a new one from summit or fordfuelinjection.com

You likely won't find a MAF harness on ebay. I suppose fordfuelinjection.com could build the harness for you, but you will not find one that is plug and play in any junkyard, much less from summit. If you buy a computer, expect to re-wire your engine compartment to match the pinout of the new computer. The kit is plug and play, and is the easiest way to do the swap, although it is a little more expensive. Going the junkyard route requires a lot of work to get everything set up properly, and finding a correctly calibrated MAF meter is hit or miss on ebay, even if it says it is calibrated for the correct injectors. Unless you are really good with wiring and want to tackle the challenge, the kit might be what you want to get. The same kit works for both 302 and 351 although the 351 needs to have a couple of injector wires swapped for the different firing order.

ok sounds good, I dont mind paying the 5 or 600 dollars for the whole thing honestly. I just want to get it converted right and if i can call summit and say " I want a MAF kit for a 92 f-150 351w" they should be able to hook me up right?

maybe, maybe not. Find out what transmission your truck has - I'm thinking it is an E4OD. If so, the ford motorsports kit will not work - it is for non-electronic automatics, so it will not control your transmission. Pro-M makes a kit, but it is even more expensive than the Ford kit. I should have thought about that earlier. If you have a C6 it would work fine, but I don't think they still had C6's in '92.

yep its got the e40d but im thinking of replacing it with something else I just like the first gear in the e4od so Im not sure what to go with or just keep it and not do the conversion. I wouldnt do the conversion if i knew how to maximize the speed density motor.

why are you wanting mass air? what are you goals with this motor. there is alot that can be done and still keep the stock system happy. if you swapped in a manual ZF 5speed tranny you may be able to use the mass air kits available. otherwise Pro-M's kits is 1500.00. thats a lot of coin man.
give us some info on what you want and lets go from there

Well i wanted to Get Performer heads and induction, headers and exhaust and a TB. but Im rebuilding the block aswell and i figured I could put in a cam that would put me up around 350 horse with those mods or at least close. Everything ive been reading says I need to go with MAF kit, I dont really want to If i can get over 300 hp with just modding the motor and rebuilding it. I was going to get it rebuilt with 9:1 pistons, I dont know if thats stock or if stock is 8.5:1 but i just figured It would bump it up to help in the power department. This is alot more of a PITA then building an FE cause i have to stay smog legal too.

ive heard of people getting away with the SD system then theres that run rich or lean..so i think its hit or miss. either way if u go with maf it'll support future upgrades that might be more extrem...like say a turbo : ) if u wanted to go to the step above maf and ur gonna do some wiring anyway u can wire it for sefi which is more efficient

MAF would be SEFI anyway; there is no 'step up.' With the tuning required to run a turbo, it's probably better off to not convert to MAF initially.
I don't know if 350 horse would be attained through those mods alone, but you would have a good amount more than stock, that's for sure. I think all of those things you listed would be within the realm of speed density, certainly nothing that a custom burned chip couldn't handle.

cool I guess If use a mild cam like the comp cam or something maybe even the performer I would be ok. Its still gonna be a truck so I can live with what i get from those mods as long as i dont need to switch to MAF. Im putting 3/4 ton springs and some tow equipment just to do light towing but I wanted the motor to get a little beef too, and my tranny makes my truck feel sluggish (178K on e4od). lol.
