I have recently purchased a Ford Motorsport E303 cam for my 94 F-150 302. I need to convert my truck from Speed Density to Mass Air. I am not very familiar with doing something like this so if anyone has any info please let me know. I placed a order with Summit Racing for the Mass Air conversion kit. But they put me on back order till Jan 15 01. And I dont feel like waiting that long. Also I need to convert my engine from Windsor firing order to 302 firing order. I have heard all I need to do is switch around my spark plug wires. Would like to know for sure before I do. So if anyone has any information please let me know. It will be appreciated.

Your truck should have a roller cam. You should also be able to use one of the Mustang roller cams for your engine.

Yes the E303 is a Mustang cam. The only thing is the mustangs have a different firing order and Mass Air. I need information on changing the firing order and converting to Mass Air. Thanks for the input though.

 

When you get your kit, it will (more than likely) have all of the instructions you will need for converting your system over plus the notes for swapping your plug wires.

Don't go putting that cam in just yet, if you do without the mass air you will throw your computer into big bad fits! My advice is wait until you get your kit and then jump off into it with both feet.

Why are you in such a hurry to do this conversion? Is there something wrong with the way your truck runs now?
My advice would be to order the kit; even if it will take til January-That's only 2 months! If you must do it now, then find the kit somewhere else, but, don't attempt this without the kit, or at least some detailed, tried, and true instructions.

[font size="1" color="#FF0000"]LAST EDITED ON 27-Nov-00 AT 01:42 AM (EST)[/font][p]I'm thinking of putting that same Mass air conversion kit on mine. Mainly because I'm planning to do upgrades to mine.....

Future upgrades:

New cam: Crane Compu-cam
K&N FIPK (in place of the K&N panel filter now in place.)
GT-40 Upper & Lower Intakes & throttle body
Complete MSD ignition (already have the MSD TFI Coil
Posi gear swap (from 3.08 to 3.55)
:-):-):-):-)

;-)(would love to add a supercharger too!) but Money doesn't grow on trees! ;-)

I used a crane cam on my 5.0 but I did install the ford motorsport mass air kit myself. It came with very good instructions and wasnt a problem at all. make sure you have the tools on hand that you will need before you start and it shouldnt take more than 3 or 4 hours. dont forget the long t-40 for the center plenum bolt. you will need to remove it to install the new wiring harness.everything was numbered and plugged right in. btw if you use your truck for any kind of towing you might want to think about a milder cam. I have installed 2 of them for other people and they kept coming back saying it realy sucks while plowing snow or pulling the mountain with a load of wood. I warned them. that cam was intended for mid to high rpm power and will probably reduce low rpm power.

 

Thanks for the info everyone. I called Ford Motorsport tech up the other day and felt kind of stupid afterward. I asked the tech how to install a Mass air kit. Since my truck has the Windsor firing order. And the kits listed are for the 302 firing order. He replied by asking me if I have a meter at the end of my air cleaner box cover with four wires coming out. I said yes. Then her told me the $650 dollar answer. "Sir the 94-96 F-series 5.0 5.8 engines are equiped with mass air from the factory." But I will feel like a ##### if it saves me $650. I returned the E303 cam for a B303. The E has more lift but the B has more duration. And duration = HP. The only thing I still dont understand is degreeing the cam 4 degrees over. So any help will be used. Thank you everyone.

 

Be carefull. Since you have MAF you also have sequential fuel injection. The injector firing order has to match the cam and distributor firing orders. The firing order for the engine should be embossed on the top of the intake manifold near the distributor. If it reads 1-2-7-2-6-5-4-8 (which matches the 351w and 5.0 HO) then you're OK. If it reads 1-5-4-2-6-3-7-8 (standard 302 order) then you have a problem; you will have to rewire the fuel injector harness to match. You CANNOT get by merely altering the firing order at the distributor. This is an integral part of the mass air conversion, so hopefully the factory made the change the same way SVO did, but that's not a guarantee. Check before you start.

You may not like the "B" cam. It requires a lot of mods to work well and makes very little bottom end torque. It works fine in a built street/strip Mustang, but your truck weigh 1000# more. You may find your truck has less usable street performance, not more.
Even the "E" cam, which IS a Crane 2040, might have too little bottom end for a heavy vehicle.

If your firing order is right, I strongly advise you to look at the Crane 2030 cam. I have one in my C/P autocross Mustang. It makes huge amounts of torque throughout its entire range with a virtually flat torque curve from 3000-5000 and a HP peak at about 5300. It is a much more streetable performance cam than the others and muchmore suited to a heavy vehicle.

Specs on the 2030:
Intake .533 lift / 270* (216* @ .050)
Exhaust .544 lift / 278* (220* @ .050)

 

I am considering at some point to put a Crane retro fit roller cam in my truck. I have been considering the Intake:212@50-.520" Exhaust:220@50-.542" model. What do you guys think of this choice? I do pull a 10,000 lb gooseneck on occasion. I currently have a Edelbrock Performer cam Int:204@50-448, Exh:214@50-472.
What kind of performance or towing gain (or loss) could I expect with this switch?

The firing order for my truck is the Windsor (302HO). So I do not have a problem their. From what I have read and talked to people I should have that much trouble with installing the B cam. The lift is around 480, So I will be able to keep the stock springs. The engine will be rebuilt as soon as the truck is paid off. So I dont want to dig to far into the engine. I am also installing a 3200 stall torque converter and 4:10 rear gears. If anybody has experience in degreeing a cam, That is the info I need. Thanks for the input!

 

I have changed many cams but never degreed one, tho I know I should. Just about any aftermarket company sells degree wheels and I am sure they come with instructions on how to do it. Occasionally there are write-ups in magazines on the procedure. All I can say for sure is retarding the cam gives more top end and advancing gives more low end, just the opposite of what you would think.
The E-303 has a touch more duration and lift than my Performer cam, which has pretty decent low end, of course I am running a few more cubes too.

I know this is old as hell but I can't for the life of me understand how an entire forum be so full of horrible advice and zero knowledge. Were we all this dumb 22 years ago? Who puts an E csm or especially a B cam designed for a 2800lb car in a 8:1 compression 4000lb truck 302 with stock E7 heads with STOCK SPRINGS a 3200 stall in a E40d with 4.10s I bet that turd ran a 26 second 1/4 at 63mph and made 240hp (30hp more than stock) around 4800rpm at full valve float. Yes switching plug wires is all one had to do to accommodate that horrible combo holy crap its hard to believe people refer back to these forums for anything other than to give a stink face and say damn were we that dumb? Apparently yes, yes we were.

 

Great first post.

There are reasons why some posts should be left alone to rot.
