Here is a picture of the I6/460 tube.
This one is for 92-96. The one for 87-91 looks a bit different. I think either will work.
Don't waste you money on a throttle body spacer. It will do absolutely nothing for and EFI motor. It really only works on carberators and throttle body injection setups.

from what i understand, unlike the rangers, which have a tubular exhaust manifold stock but a baffle inside the air intake hose that blocks airflow, these trucks have pretty good air intakes stock, it's the exhaust that's holding them back

I'm not sure I understand the question about special valve covers. Your stock valve covers won't work anymore? Whats been modified?
If you talking about EFI valve covers then yes they do sell valve covers for EFI. The valve covers for the older motors won't work out right.

I never found a baffle in the air intake tube. Thats not to say that some trucks don't have it.
What I think is really holding these trucks back especailly the ones with the 302 is the fact that the rearend gears are too high (numerically lower) for the 302's power band. This is also true of the 351. The 4.9 is a different animal though and needs 3.08 to 3.55 since it is a low reving motor. The 302 doesn't make much low end power for a truck. So, if the gear ratio is not very good and it has overdrive transmission it will lug on the highway. The best gear ratio for a 302 with overdrive is probalby at least 3.55 or 3.73. Some of them came with 3.08 and 3.31. Many of these trucks came with lousy gears. Better gears will not only increase the performance of the truck but can also increase fuel economy as well depending on the setup.
Another thing that is holding these truck back is the fact that the cam Ford went with is too mild. Conanski is the one to ask about that stuff.

I was just looking at valve covers from summit and someone told me the ones in there wont fit because of something special on my truck and that the only ones i can use on my particular truck are the Ford Racing ones which are like $80. Id just like to dress up my motor a little without breaking the bank.
I have a Thrush muffler now, i plan on pulling my 2 stock cats and putting one on and putting another muffler on to to abide by my local laws.

the baffle was in the rangers air intake tubes. It was apparently because they were getting "too much air" to slow the truck with the engine. Removed it and got alot more torque out of it. 2.3L with 123k miles so nowhere near actual torque, but you know what i mean. It doesn't engine brake as well without it, but i only downshift to slow down in the snow anyway. My 302 has 3.55s and I honestly think they're a little too tall. Stock tires yeah I get nice launches from footbraking and I can hold overdrive even with 2000 in the bed, but anything bigger tirewise, I'd want 3.73s or 4.10s. 302s are utterly torqueless, the 351W on the other hand has a ton of torque, and the 300 is great with 3.55s or 3.73s, you just gotta realize you aren't gonna be moving fast. If you want proof find an old f350 with the 300 and 4.56s. I was dumbfounded when I heard that but all the guy did was haul mulch and debris in the dump bed with it for his landscaping company, so it works for him because he never sees the highway.

I completely agree about the 32s, even with stocksize tires I have absolutely no low end, but my buddy says his 302 3.55s and 33s is fine but he has a stick so who knows. He runs shorty headers into thrush glass packs through 5" stacks though, So he gets some torque from his exhaust. He also has a throttle body spacer and true ram air through a hood scoop. Also enough addons he welded himself and suspension parts to put his curb weight up to almost 5000. He's swapping over to 10.25 axles with f250 suspension and 4.10s soon though. He'll see then what he was missing.

My stepdad has the smae as me 1989 shortbed 302 EFI but his is a stick, he has F250 suspension, 35"s on the stock alcoa ( sp? ) wheels and just a cat with no muffler i believe in 3" pipe coming out of the passenger side. His truck is a beast on the low end but we have a 351W in the basement he is building to do a swap.

he already has done the suspension swap. He has a 2" lift to put in the front to level it out. That thing will pull and haul some surprising stuff for an F150, he gets a lot of looks from people wondering how he pulls what he does.
