1994 5.8L Upgrade ???
New to the forum but hoping one of you guys might be able to point me in a direction. I have a 1994 F150 4x4 with the 5.8L and EOD tranny. I've added about all of the bolt on stuff - hypertech chip, shorty headers, flowmaster exhaust, K&N filter, throttlebody spacer, etc. and also upgraded by electrical a bit with a higher voltage coil, plug wires etc. The truck runs decent - but - I would really like to wake it up big time. A few months back I was chasing down new heads, cam, etc and found out that I am at an apparent dead end with this thing because it does not have a mass air system and none are available for it.
Does anyone know of a MAF conversion available for this year truck or any way around this apparent delema? I would like to get this thing pushed to around 400 hp - and still be able to pass inspection!

There are *numerous* MAF upgrade packages, and I recommend using the unit from Ford Racing's catalog - and then have us do a custom tune for it, as not only will you no longer be able to use your Hypertech chip with the MAF conversion, but we make far larger power gains and get much better driveability than they do as we have specialized in the F-150 platform for 14+ years now.
It's not hard to get a 5.8 to 400 HP at the crank, but as you said, you will have to do more work - heads, cam, etc., and mass air is the way to go to get that done and still have a vehicle with excellent driveability.
As to still passing emissions in a true sniff test, that is really a matter of what camshaft you choose, so again, go thru the Ford racing catalog for that - and then come to us for your final tuning, we'll make everything run correctly together and get maximum HP, torque and usable performance out of it.
Nice to see someone else keeping the older F-150's alive, & best of luck with your project!

My appologies for the long delay in getting back on here after leaving the questions. I appreciate the response. I did check with Ford Racing and they do not make a MAF kit for my truck. They have one for everything imagionable but not for a 94' 5.8L with the EOD tranny. I see Summit lists a complete system now with a whole new computer and MAF kit for the 5.8L. Would this work on mine?

Hi Stumper,
We are located out in the western part of the state, out in the mountains - basically in the Millboro/Covington area, to give you a rough idea.
I can't tell you if Summit's setup will work, but with some homework and a bit of digging, you can convert that 5.8 to mass air - worst case, I would say to shoot for a Ford 5.0-based setup as long as it's for a 5.0 with an E4OD tranny - see, that is the key, is you need the conversion for the E4OD transmission specifically, as it is computer-controlled in the 1994 and Ford determines what PCM is used in automatic transmission vehicles based on the exact model of the transmission - E4OD/4R100, 4R70W, etc. Generally speaking, I would go that route before I would ever think of going to a standalone system conversion that does not use a Ford PCM, unless I was building a 750+ HP monster, and even then, we can usually make the Ford PCM from that timeframe handle up to about 750-800 HP as long as the mechanical configuration is correctly selected (heads, cam, etc.).

Do you think the mass air kit from a 5.0L with the EOD tranny would work? Would it have to be the same year? I wish I knew someone who has gone down this road before. Mechanical stuff I can understand but these darn computers boggle my mind!! 
Thanks!
Thanks!
