My ole 5.0 is getting tired. I was wondering if anyone has ever taken a Mustang 5.0 HO and made the swap. If so what is involved. I have already talked to Jegs and Hyperteck and obtained the part number for the Power Module needed for the computer but how 'bout the other things? Is this a direct bolt in? Will my headers from my 302 fit the HO? Would I need to install a higher pressure fuel pump? Etc....????

If not does anyone know where to find out this info?

Thanks

Tim

 

A lot of what you have to do depends on the model year difference. I have an 87 F150xlt with an 89 Lincoln HO motor, it was pretty straight forward, very few changes required. (My nephew did the swap, I bought the truck from him after). The electronics are basically the same. If you went with a newer 302 HO, you'd have lots of changing to do.

 

It's a direct bolt in with the truck oilpan and pickup, and truck intake. You don't need the chip, FPR, or fuel pump, and the truck computer and wiring harness will drive it fine. The only other thing of note is that the HO firing order is different than the truck, but all you need to do is keep the HO plug wires routed as they come.

 

You are right Paul. I talked with Ford Performance today and they told me the exact same thing.

And since I have talked with them, I think I have decided to kill the conversion idea and rebuild mine. I am going to install aluminum, higher compression heads; a mass-air conversion kit, and cam. Jim from Ford Performance hooked me up with a guy that can grind me a roller cam to my specs per my application (for those that didnt know, as I, this block of mine is the same as the HO and will accept a roller or flat-tappet cam). And with these mods I should be pushing 390hp.

Thanks Guys

 

Where are you going to get your Mass Air Conversion kit? What all mods are you going to be running to get 390hp?

 

Check this link out...it will carry you to the Ford Racing page for the Mass-Air Conversion:

http://www.fordracingparts.com/parts...tKeyField=1179

The guy at Ford Racing Performance told me today with the mass-air, with the roller cam profile I chose (part #M-6250-Z303), the higher compression "Z304" heads(which with the flat tops will bring it up to 10:1) and with the headers he estimated the hp to be around 390hp w/360 ft/lbs of torque. If I had went with the 9:1 compression it would ran at 360 hp w/330 ft/lbs of torque

 

WOW that cam has a HUGE lope. Thats going to be hard as a daily driver dont you think. Thats messed up when I called FRPP they told me they didnt make those. You going to do anything with the pistons. With that cam you will have piston to valve clearance issues.

 

As you probably know the lift on a roller maybe larger than a flat but you achieve the same results as with a smaller flat cam. The Valve lift is .552" intake and exhaust. Duration at .050" is 228 degrees intake and exhaust. I know that it does sound radical but it is classified as a mid-range torque cam. Plus I am running a 5 speed so the drivability shouldn’t be affected that much. I know I ran a hyd. flat "Comp Cam" with a .502 lift and 292 duration in my Windsor w/ a 3500 stall (in a my Ranger "bracket car") and I am expecting this cam to be milder. As you can see the duration is alot smaller. Although this will be my first "roller" I have ever ran, I dont forsee any problems. I just told the dude I wanted to build me a motor around 400 hp to be a daily driver and then he made the recommendations. He told me that stock flat-tops is the recommendation for this combo. In any other of the engines I have built I know what kind of cam I need for a specific need, whether it be solid or hyd. But this roller stuff is new territority for me so I am trusting the guys judgement. If you or anyone thinks he is wrong let me know, I am all ears, I am in uncharted waters with this roller stuff...LOL

 

You'll need an intake other than the stock truck intake then, it won't play nice with those parts. I'm thinking something with significantly shorter runners... Holley Systemax or the like.

 

I did think about that Paul but I forgot to mention it to the dude...and he didnt mention it when I asked if I would need anything else. I wonder if he forgot? Thanks for bringing that up...I will have to ask him.

 

I am sure that Cam will work since he is a builder he would know. To me though for a daily driver that is a HUGE cam. Look up the Ford Racing Z303 cam on the net. Its the BIGGEST cam that Ford makes called the Camzilla. Most people use the E303 cam on a daily driver truck. Either way when its done I would LOVE to hear that thing. Your truck will move to the lope of the cam lol.

 

well you are right...I looked it up and after comparing the two, he might have said "E" rather than "Z". I probably misunderstood him. I didnt know that they came in a E, F, B, and X. And after looking at their profiles I think I like the "E" or "F" better. I will have to call the man back and ask him exactly which one he recommended and how would it effect HP if I went say with the "F303".

Thanks for bringing that to my attention

I drove a 84 Mustang with the E303 Cam Saturday and it was nice. Take off was alittle different for me I have never driven a 5spd with a Cam. Are you ordering the parts for your motor yourself or you having the guy order them directly from Ford? If you are ordering the parts yourself and decided to go with the E303 Cam let me know. I have a new E303 Camshaft kit
Kit Includes:
Ford Racing camshaft
Ford Racing hydraulic-roller lifters
Mr. Gasket cam change gasket kit
Permatex engine assembly lube
Has everything for the install.

 

i got questions, 1st what trans? if your not running a e4od, go the the junk yard and pull the harness pcm and needed sensors of a 89+ 5.0 mustang , or 91-93 tbird-cougar with a 5.0. they are aod cars and are mass air and 5.0 ho . this will be a minimal effort & cost for making this truck run right. the ford racing stuff is great but i always found the price on their mass air kit to be a little much for what you get. the cams you cant go wrong, i persoanlly think the e303 is too little cam for such a heavy truck . fuel pumps. depends how far you want to go , i personally would do 190 lph or higher . these should supply enough fuel as long as you stay normally aspriated. dont forget injectors too. i would minimal of 24lb .

 

I think I am going to go order my parts from a FRP Dealer here in Atlanta and I think I am going to go with the F303 but I appreciate that offer. I am not ready to order anyway. I still have to get my truck out of the body shop, I took it in this morning to have it painted, then I am going to tackle the motor.
