Is there any company out there that sells a stock lower intake manifold for a 1989 Ford F150 302

 

I have never seen any company selling a new truck intake manifold. Go to the junkyard, any '87 to '92 5.0 truck will have the piece you need.

 

No idea.

I mean, surely there is a NOS one somewhere for what would certainly be an exorbitant price. Ford made just too darn many, but they aren't known for failure & I can't believe an aftermarket co would tool up to make them. What might be your objection to using a plentiful & relatively cheap used one?

 

I replaced my rear end with junk yard parts. The front cap is from a 96. I don't have problems with junk yards for some parts. I do have a problem with parts that corrode. I have a leak at the bottom of the thermostat housing on the manifold. The part has over 300,000 miles. I replaced the hose neck a couple of years ago because of corrosion. I've been reading a lot on this and some say the lower manifold of some custom applications basically use the lower manifold of the truck because of it's breathing ability. I thought someone may have tried. The only other application I see is the 3841 Edelbrock application. I tow horses across the country with a custom built 302 that runs a motorhome camshaft and Edlebrock Cat back Exaust. The transmission is custom built by Monster to run with this setup with a little more stall on the converter. The master cylinder and rear wheel cylinder are F350's. My son took the truck down to the frame and replaced all the rubber mounts. He then applied about three coats of Honda Black with a blue pearl on the bottom up to the door handles, the top half has a Viper medium blue with purple pearl. The bench seats were junked for a set of 95 Ford F350 cloth 40-20-40's for the long ride. The truck is what ford built to use for an overhead camper. It has factory helper springs. I run Yokohama tires, XL's in the front and C's on the rear. Edelbrock has assured me the 3841's will come as close to stock as I can find.

 

That Edelbrock truck intake is the one aftermarket intake system(upper and lower) that would replace the stock truck intake system closest with no additional parts. There are lots of other aftermarket intake systems for the 5.0 but they all require other additional parts like a throttlebody, EGR spacer, throttle cable, and intake ducting.

 

Holley systemax lower is a direct replacement for the 302 truck lower. (Research 87-95 mustang Holley systemax lower intake)
Holley actually "stole" the design from ford because it needed little to no improvement.

 

Thanks guys, I checked with Holley, they said it won't work. It has no internal EGR. I googled it trying to find out if anyone has converted it to work with EGR. I didn't locate anyone that had.

 

Trucks don't use internal egr. Pipe comes from passenger manifold up to egr valve that's on the side of the upper intake.
It will work just fine.
Put a location in your preferences so it shows up in the top right corner of your posts.
Do you need to pass emissions.

 

Only on the 5.8 motor, on the 5.0 it's internally ported through the lower intake and then it goes external up to the valve. Your guess is as good as mine as to why it's different on these two motors.. it's a Ford thing. But that brings up a good alternative, the OP could connect the tube to the passenger side manifold/header just like the 5.8, or just leave the tube off and block the EGR valve if an emissions inspection isn't a requirement.

 

Aaah. Yup. Just looked it up. Drill and tap the exhaust manifold for a new egr pipe. Make it like the 5.8 like was suggested.

I still say who cares.
I wouldn't buy a new one anyway. Go to junkyard and get one like was said before. I'll pay the 30 bucks for a used one before I'd spend my money on a new one.

 

Great, thanks for the info, that shouldn't be hard to do.
