f150 Question

[89sport]

I just want to make sure that my research is correct. My uncle is wanting to give me a 90 F150 with a rebuilt 302 with under 45k miles that was hit badly in the bed. From what I have researched the f150 302 is taller and not as performance friendly as the car 302's? I want to make sure because I'm really looking for a mass air 302 and dont want to have to modify the truck more to get the 302 to fit more than a car 302. I also want the engine to respond well to mod's later down the line and would hate to pass up a 302 if it will work.

Thanks in advance

The intake I believe is taller. If you wanted to make it work you could.

so lets say i take the entire intake manifold setup from a mustang motor it would be the same height as the mustang motor?

Also important is if the f150 oil pan will work or will i need a different one?

The intake is a heck of a lot taller than the mustang and as long as the oil pan is double humped, it should work, maybe.














Trust me, by the time you're done, the only thing you will be using from the f-150 is the block, that's it.

Mine is from an 89 f-150 and everything off it was scraped because none of the parts fit or worked out very well.

There's not much performance upgrades for the f-150 setup because it should be speed density vs. the much better MAF setup, which makes things harder to work with if you wanted to do engine upgrades.

Here's what I would do: Get the motor from your uncle and get a 302 from a non-HO mustang in the 89-93 era. Get the computer, wiring harness, Mass Air Flow sensor, fuel rail, everything from that mustang and transfer it over to the f-150 motor.

Short story:
Mustang= Mass avalability and very upgradable for more power
F-150= Just not the best thing

Again, trust me on this. Lots of money was flushed down the toilet because of parts not working and not interchangable.

Thanks thats what i thought. I am going to pass on it just because it may be harder for me to get rid of all of it as im seeing tons of them on craigslist that seem to not be selling. I will just wait for a 89-93 302 maf from a car to find me

The only parts different are the intake and oilpan. Everything else is basically the same as a Mustang 302, except the cam. Same block, crank, rods, heads. The accessory drive is slightly different, but nothing that would prevent you from using it over a mustang setup. If he's giving it to you, it would be foolish to pass on it.

Don't pass it up. I had to find out the hard way what did and didn't work. Plus I paid $500 for the whole engine and computer and such, plus an extra$1500 for the rebuild kit, machine work, and engine work.

One way or the other, you will be spending some coin on this motor, but if it's rebuilt and gone through already, that's almost 2 grand taken care of.



Plus, what's to say a motor setup from a Mustang or another car won't be a trashed motor and they failed to mention it?? Now you'll be some cash short and a worthless hunk of iron is taking up space in the garage.............

Are all 89-93 302 from the stang, crown, mark, f150 all forged piston w/ rollers?

I really want to have a nice start with a roller forged block just in case i decided to do more upgrades later in time.


I totally haven't ruled out the f150 but its a 2 hour drive to get it and then the time spent taking it out.

No, only the 85 to 92 (or was it 93?) HO 5.0's (in addition to the Mustang HO motor, these were also installed in the same years Lincoln Mark VII LS) had the forged pistons. But forged pistons are not a requirement for a high performance engine. Most of the old 60's HP motors had cast pistons. If you're going to spray the piss out of it or supercharge it, then yea, forged pistons would be neccessary. But otherwise, they're not.

Just slap a Performer intake with a Edelbrock 500 on it. Problem solved.

I plan on putting a supercharger on it late down the line as they make several good ones that can run somewhat low pressure for cast. That and I may put some 32-40lb injectors and run E85 since its high octane and is pretty clean. Had a buddy run E85 in his 400 sbc and we tore it down after a year of cruising along with a run at the strip at least twice a month during summer and that thing was cleaner after than it was before . But I am still unsure about running E85 as I have to wait till i get the motor first.

Can't do a carb, I never go back in technology with cars or trucks. So since i have efi and a manual its going to be a efi v8 with a t5.


I also just found a 89 crown vic that i may take everything out of and swap my buddys old 91 stang top end and do a better cam while I got it apart. But i am still trying to figure out what the difference is between the 91 stang and the 89 vic top end and that atm to make up my mind.

And thanks for all the info guys!

The Vics had different heads and pistons with no valve reliefs (didn't need em with the heads they had) They had a roller cam but it was the smallest of the production roller cams.

I was looking to put on different heads on whatever engine I get. I think my buddy said he had the gt40 heads and a new e303 he would part with for dirt cheap.

Would the harness and computer from the vic work if i find a mustang motor? I think I just found one but unsure of its year. I keep finding 88 stang computers but I don't know if that would work with a maf system.

I believe you're right, my friend's 5.0L HO from a '93 T-bird has hypertech pistons.

You will run into valve clearance issues bolting GT40's and an E cam onto a 302 that's got no valve reliefs in the pistons. Ford Racing sold a wiring kit to convert SD systems to MAF. I can't tell you if a Vic computer will work though. I'm a carb guy.
