im kind of in a debate right now weather i just want to save up and build my 96 speed density or if i should spring for the MAF conversion? What would the conversion cost, and how hard would the install be?

 

Not alot of people do this im asuming? lol

 

Actually alot of people have done it. It all depends on what your wanting to do with the motor. I am currently building a 351 from a 96 3/4 ton to put in my 94 F150. My goals were modest so SD is going to be OK. I am aiming for 300HP and 400 FTlbs of torque. Anything above that and you are probably looking at a Maf conversion. Now I am not the authority on this just voicing my opinion.

So far mine will have
roller cam
1.7 roller rockers
GT40 heads ported and polished
Flat top pistons
Long Tube headers
Still undecided on the cam

 

What he ^^^ said. You have to ask a "quality" question if you want a quality answer.

 

300 Hp / 400 Ft Lbs . Those sound like excellent numbers for an SD. If my engine ever throws in the towel. I would do a set up like your planning in a heart beat. A great plan IMO. I would like to hear how it works out. Porting heads in any build is one of the most important items for me, and is on the gotta do list, along with headers and a cam selection suited for your needs.
As you said "depends on what your wanting to do with the motor". For me that is a fresh build with more torque, for my 4x4 .

My 92 as you know is SD. What year did Maf start,,,, 95 ??

Best to Ya with your build, '92

 

Porting heads is fun but it's not necessary at this power level if GT40s are substituted for the stock heads. I'm not trying to discourage someone from experimenting with porting though just redirect them to put that effort where it'll pay bigger dividends. GT40s already flow 20% better than E7s which is enough to produce these power levels comfortably, but that much gain is harder to achieve from E7s without a lot of porting experience and access to a flow bench so it's not likely a first timer will get anywhere close. Instead focus on the part of the puzzle that does need attention.. the 5.8 truck intake. One solution here is to use the much better 5.0 truck intake with a set of adapter plates from Price Motorsports, or you can break out the die grinder and open up and straighten the ports in the lower section of the 5.8 intake. And of course you can get the same results with GT40 heads on a 347 stroker.. no adapters necessary.

 

Maf is required when changing too much of the stock motor. Sure you could buy a new management unit, but you could easily adapt to a mustang ECM. All it takes is Money.

 

well i dont plan on building a 300hp motor any time soon just cam, rockers, possible headers thats all ill just stick wwith SD thanks for your input guys

 

I am going to try to answer your question according to what I believe I have learned from alot of research prior to starting this.
Maf came out in the 95 California models and in 96 for the rest of the US. Now this is where I may be wrong. The 96-97 3/4 tons were still SD because they did not have to meet the earlier emission standards since they are considered "work trucks". I have a build thread on this truck I am going to update soon called the Old Green Ford.

For anyone "planning" build and with lots of time by all means look for Maf. I wanted to be finished installed and pulling my 5th wheel by mid summer so time was getting to me. Finding a factory Maf truck will take some time.

 

That would be the OBD2 MAF version, there is also an OBD1 version that appeared as early as 1994 in Cali and everywhere else in '95.

 

Answer the question of what you want to do first. You say cam, rockers, headers...if you go too big you will be forced to convert to MASS Air to tune the computer and get the motor working (that's what I did). You can do these things in an SD motor and as long as you don't go too large is what I am saying. You probably won't see any performance difference if you were to do these changes in an SD system vs a MASS Air system.

 

96 has a roller cam. Just add 1.7RR, gt40 heads, long tube headers and a full exhaust and you'll be at that 300hp mark

 

alrighty Bray09 ill take your advice!

 

My 94 has 1.7 ratio RR, I ported the heads (E7), put better springs on and shorty headers with SD - works great. I do not know the HP gain is but I can pull a trailier with dirts bikes in the bed up some steep hills in mid range 2nd gear where before I had to go into first gear. My truck has a 302/5.0 and the intake is better than most (Conanski is correct). With the 1.7 roller rockers the stock cam moves about half way to a "improved" cam which are normally designed for cars and not trucks. So I would rethink the need to move to a more agressive cam, but as many have said it all depends on what you want.

 

I never knew that. Nice information, thank you.
